How did the only city in China named after "flower" achieve a hardcore counterattack?

It is the 60th anniversary of Panzhihua's development and construction

I would like to express my infinite blessings and highest respect to you through this article.

Not all Sichuanese

All speak Sichuan dialect

Not all resource-based cities

All are old and frail

At least, Panzhihua is not

(Looking up at the starry sky at Xifo Temple in the western part of Panzhihua is very sci-fi, photographer @野蛇)

▼

Young people are familiar with it

Because it is known as the "Steel Capital of China"

Frequently appeared on geography test papers

Make your presence felt in front of students

Older people love it

Because it is known as the "First Health Care City in Southwest China"

The annual sunshine hours are comparable to Sanya

Flowers bloom and fruits are abundant all year round

(Panzhihua is also nicknamed "Little Sanya in Sichuan" by netizens; the picture below is a Panzhihua tourist check-in map, drawn by @Jingyi/Planet Research Institute)

▼

However, few people have studied

Whether tough or tender

It's not from its "talent"

Over the past 60 years

How many years of obscurity

Witness the difficulties of Panzhihua's rise from desolation

Even if there are more doubts from the outside world

It didn't retreat at all.

(The inscription on the Panzhihua Heroes Monument reads "This monument is dedicated to the people who came from all over the country to the Jinsha River to build this new city since the 1960s, in memory of the heroes who dedicated their youth, wisdom and even their lives to the development and construction of the Panzhihua Industrial Base...", map by @Jingyi/Planetary Research Institute, photographer @Shilei)

So

What exactly is Panzhihua?

It is an iron fortress, a city full of romance, and a national attack.

“ Three desperate reforms ”

Only then did Panzhihua have its physical body reshaped.

The towering monument on Bingcaogang with mountains behind it

It points to the starting point of the story

01

Mineral Deposits Transformation

-Iron Blood Fortress-

1960s

The United States dispatched the Seventh Fleet to intervene in the Vietnam War

Fighting spreads to southern China

Sino-Soviet relations deteriorated, and Sino-Indian military conflicts broke out.

National defense security is seriously threatened

A grand concept called " Doomsday Project " was born

If a war breaks out

Coastal areas are unreliable

The existing steel mills are also within the enemy's bombing range.

What’s the point of fighting without steel?

China's industrial system must be

Migrate to the southwest hinterland with high mountains and far waters

(The "Doomsday Project" refers to the Third Line Construction; the picture below is a schematic diagram of the Third Line Construction, drawn by @Jingyi/Planet Research Institute)

▼

This also means

Able to rely on rich mineral resources

Build a large-scale steel base with independent self-circulation

It is the most important part of the whole plan.

actually

It's not difficult to find such a place

As early as 30 years ago

The "Western China Academy of Sciences" organized a geological survey team

Exploration into the Southwest

After several detailed measurements

It is on the top of Zhujiabao Mountain in the southern part of Hengduan Mountain.

Hundreds of millions of tons of magnetite have been discovered

(Chang Longqing is one of the discoverers of Panzhihua vanadium-titanium magnetite; the picture below is the sculpture of Chang Longqing in Panzhihua, drawn by @Jingyi/Planetary Research Institute, photographer @Li Changhua)

▼

About 200 million years ago

This place happens to be above a huge mantle plume

Strong magma activity erupts

This is how the huge mineral deposit was formed.

But the special thing is

The ore contains iron, vanadium, titanium , etc.

Multi-metallic element complex symbiosis

The smelting process is extremely complicated

(Sketch of geological structure and mineral resources in Panxi area, drawn by @Jingyi/Planet Research Institute)

▼

April 1959

A total of more than 300 boxes of nearly 20 tons of mineral samples

Sent to the Soviet Union for testing, where technology was more advanced

The titanium dioxide content of the generated slag is as high as 30% or more

This can easily lead to the international problem of slag and iron being sticky and indistinguishable

Only a large joint test site in developed countries can solve

Unavailable in China

" Dumb Mine "

Foreign experts not only say no

Also commented very "regrettably"

Why give these treasures to the Chinese?

They can't make iron.

The treasure will sleep forever

(When the titanium dioxide in the slag reaches a certain value, a large amount of gas will be dispersed in the slag in the form of bubbles, causing the volume of the slag to expand. This kind of slag is foam slag; please watch it in horizontal mode , Panzhihua Lanjian Iron Mine, photographer @林东军)

▼

No country is strong

It's innate

You must strive for strength yourself

May 1964

The CPC Central Committee convened a meeting on the Third Front Construction

Ministry of Geology, Ministry of Communications, Ministry of Metallurgy, Ministry of Coal, Ministry of Electric Power, etc.

Hundreds of experts from various departments gathered in Sichuan

12 professional teams were divided into two groups for field investigation

It was finally decided that this piece of land was the best location for a steel plant.

(Related pictures of the construction of the third line in Panzhihua, drawn by @Noya/Planet Research Institute, picture source @Luo Kanglin & Chen Shicun)

▼

It is not only rich in resources, but also has a hidden location.

Surrounded by the turbulent Jinsha River

Supply of inexhaustible industrial water

( Please watch it in horizontal mode . The rare clouds and mist in Panzhihua add a hazy beauty to it. Photographer: @石磊)

▼

In order to achieve the goal as soon as possible

The plan is divided into two major battlefields

First is

"Conquer the smelting of vanadium-titanium magnetite in ordinary blast furnaces"

At that time, the domestic steel industry was first-class

Beijing Iron and Steel Research Institute, Chongqing University and other universities and institutions

A total of 108 technical backbones were selected

It is known as the largest scientific and technological battle in the history of my country's metallurgy

(The hands of a Panzhihua pneumatic drill worker are full of vicissitudes, photographer @谭文军)

▼

Jin Shuliang, President of Northeastern University of Technology

I earnestly advise everyone

The urgent need for national construction is the direction of scientific research

A team of more than 40 teachers and students

Take the initiative to go to libraries and bookstores to collect as much foreign information as possible

Translate and bind the documents quickly around the clock

It became the enlightenment textbook for blast furnace smelting of the experimental group at that time

(Jin Shuliang was the editor-in-chief of Modern Ironmaking, the first monograph on ironmaking in my country; the picture below is a bird's-eye view of the brightly lit Panzhihua city, photographer @雪域修罗)

▼

Since the mine has not yet been mined

They proposed to use Chengde iron concentrate and titanium concentrate for simulation experiments

In exchange for more smelting data

Holes are also drilled in the throat, waist and belly of the blast furnace.

To take out each layer of charge for analysis

Every time a hole is opened

The hot air flow above 1000℃ is mixed with ore splashing

Let out a terrifying howl like a wild beast

Some people put asbestos aprons on their shoulders to act as a barrier.

Some people hold a several-meter-long tube spoon to take samples

Various dangerous situations emerge in an endless stream

Such as work clothes being burned through, blast furnace parts falling, instrument bottles exploding

(Workers working hard at the modern Panzhihua Steel Plant, photographer @李昌华)

▼

Up to thousands of attempts

Successfully separating slag from pig iron

Accumulated valuable process parameters and operating experience

Lays the technical foundation for smelting

They always abide by a principle

That's confidentiality

About their past

It was not known until half a century later

Another battlefield

“Building a Steel Base”

The momentum is extremely huge

March 4, 1965

Mao Zedong read the written report on the preparations for the special zone

Comment: "This is a good one"

Panzhihua Special Zone is named after the Panzhihua trees growing there.

Since its establishment

(Panzhihua Special Economic Zone was originally called "Dukou"; the picture below shows the Panzhihua tree in Panzhihua, photographer @林东军)

▼

The famous steel mill

Anshan Iron and Steel, Benxi Iron and Steel, Shougang, Wuhan Iron and Steel, Chongqing Iron and Steel, etc.

Send tens of thousands of elite soldiers

The 19th Metallurgical Construction Group of the Ministry of Metallurgy from Wuhan

Coordinate survey, design, construction and production

It was the largest metallurgical construction corps in China at that time.

Known as the "field army without uniforms"

(Third-line construction workers at that time, picture source @陈石存, map @李诺雅/Planet Research Institute)

but

As they were jolted for days on the Liberation truck

When you actually arrive at the drop-off location

Everyone was shocked by the scene before them.

Looking up, I see weeds and gullies everywhere.

Can't even find flat land

The so-called special zone

No houses, no roads, no electricity

People can only temporarily tie up

Huts, mat huts and tents

So they jokingly called it

" Three Sheds City "

Go to work every day

Essential straw hat, water bottle, flashlight

A basin of water for washing face in the morning, scrubbing back at noon, and washing feet at night

It also needs to be sent to the construction site to be mixed with mud to make bricks

(The following is from "Nongnongping" by Zhou Qiong)

▼

"There is nothing but difficulties here, and we have nothing but a pair of hands."

certainly

They also have bold imaginations

Although the location of the factory

On a hillside with an area of ​​only 2.5 square kilometers

But through creative large-scale explosion

Flatten the hillside into 23 small steps

Like 3D carving in ivory

(Nongnongping is the steel plant with the smallest floor space per ton of steel in the world; the following picture is a comparison of Nongnongping in different periods, drawn by @Noya/Planet Research Institute, and photographed by @Chen Shicun & Shi Lei)

▼

They also have amazing perseverance.

A machine that is tens of meters long and weighs dozens of tons

It all depends on people carrying it on their shoulders, pulling it with ropes and pushing it with hands.

Sometimes more than 200 poles are broken in one day.

In the absence of manufacturing equipment

Cut with a shovel little by little, and grind with a grinding wheel little by little

(Today, Panzhihua still retains the style of industrial punk; the picture below shows the operation area of ​​Panzhihua Iron and Steel West Slag Yard at work, photographer @王煜豪)

▼

at the same time

Construction of the Chengdu-Kunming Railway connecting Panzhihua begins

Passing through a 500-kilometer-long earthquake zone with magnitudes 7 to 9

Conquer challenges such as fault fracture, soft rock deformation, karst rock burst, etc.

A total of 991 bridges were built and 427 tunnels were dug

More than 2,000 people are buried here.

(The Chengdu-Kunming Railway is known as "one of the three great miracles symbolizing mankind's conquest of nature in the 20th century"; the picture below shows a train passing through the Panzhihua section of the new Chengdu-Kunming Railway, photographer @李昌华)

Taking turns playing revolutionary songs

Celebrating the opening of Chengdu-Kunming Railway

Many builders burst into tears

Because that's the way home.

And just the day before

Panzhihua No.1 blast furnace produces first batch of hot metal

This marks the start of production of the first phase of Panzhihua Iron and Steel Project

It also marks the beginning of the city construction

If we go back to 50 years ago

Standing on the river bank and watching

The situation is quite different

Dozens of chimneys look like huge black hands

Puffing out grayish-yellow smoke

The dry and barren river valley is lifeless

(Panzhihua is the first prefecture-level city that the upper reaches of the Yangtze River pass through; the picture below is the Jinsha River Valley, photographer @盛跃)

▼

This area is located in the transition zone between two plateaus.

The river cuts along the huge drop

Forming deep canyons

Such terrain not only blocks the cold air from moving south,

When the wet monsoon falls into the valley

The temperature will gradually increase as the altitude decreases.

(The warming phenomenon mentioned above is also called the "foehn effect"; the figure below is a schematic diagram of the foehn effect, drawn by @松菇/星球研究院)

▼

Hot and dry regional climate

Restricts the growth of many moisture-loving plants

Serious soil erosion

The ecological environment is the residents

The basis for survival

In 1975, Panzhihua took the lead in establishing an environmental protection agency

Controlling factory emissions

Dedicated to greening the city's vision

(Today, the gases emitted by Panzhihua factories undergo multiple processes, and most of them are water vapor; the picture below is the green Panzhihua Park, photographer @王煜豪)

In the past, people were so poor that they could not get enough food.

We have to cut down trees for infrastructure construction

Yang Rongxi, who graduated from Beijing Forestry University

He is the first generation of lumberjacks in Panzhihua

Responsible for supplying wood for major projects

Until people's lives get better

How to return the green we owe to nature

Often troubled his mind

Jinsha River Dry-Hot Valley

The ecology is extremely fragile

The difficulty of repair is simply beyond the standard

It was once regarded by the world forestry community as

“ Forestation restricted area ”

October 1983

Yang Rongxi transferred to Panzhihua Forestry Institute

Meet Xu Jian from Guangdong

Over the past 10 years, Xu Jian has contributed his life's learning

From subtropical areas with similar climates

Nearly 2,000 species of plants have been introduced

More than 800 species have been successfully cultivated using the "Sea of ​​Trees" strategy

Provided up to 2 million seedlings

In the main urban area of ​​Panzhihua

The tailings were once stored in the

Majiatian tailings pond

Dust is everywhere

As the reservoir level gradually rises

It even engulfed the nearby village houses.

Panzhihua's unique climate

Became a refuge for Ice Age relict cycads

Farm reclamation, mining, and illegal excavation activities in modern times

It destroyed their living environment.

Leading to a sharp decline in the number

In order to save this precious plant

Researchers are rapidly carrying out ex situ conservation

Using methods such as introduction and domestication, artificial pollination and breeding

Re-flowering of 389,200 cycads

In 1996, Panzhihua Cycad Nature Reserve

Promoted to a national nature reserve

Land acquired for limestone quarrying

Most of them are within the red line of the protected area.

The deputy director of the limestone mine once did some calculations

The company's losses are expected to exceed 100 million yuan after the mine is withdrawn

After multiple discussions

The workers finally bid farewell to the mine

But he became an ecological guardian

The villagers light kerosene lamps and live in thatched houses.

The average annual income is less than 300 yuan

Mango cultivation is a profitable

Maybe it can lead the villagers out of poverty and into prosperity

Planting on the barren hills of my own

Just 3 years later

The mango tree finally grew in this strange land.

Flowering and fruiting

It is worth mentioning that

Panzhihua's planting conditions are certainly excellent

For example, the hillside has good ventilation and light transmission

The valley gathers heat quickly during the day and dissipates heat quickly at night

The temperature difference between day and night is conducive to sugar accumulation

But there is only one fatal disadvantage

' Water shortage '

China's Sunniest Mountain City

-A Better Tomorrow-

So far

Mineral resources, ecology, industry

“ Three major transformations ”

Panzhihua, a city with expressways, bustling airports and fading fireworks

In front of the public

Only when you truly understand it

Only then did I realize that it is worthy of being called " China's Sunniest Mountain City "

Not only represents the beautiful scenery

And its years

Can heal every difficult and low moment

Greatness comes from smallness

We are all swept away by the tide of the times

But there are always people who refuse to bow their heads and admit defeat

Take control of your own path

This is the spirit of Panzhihua

There is no such thing as debuting at the peak.

It's just the sacrifice of generations

(Panzhihua workers are working under construction in the sun, photographer @王东)

There is no such thing as a hero falling from the sky

Everyone who lives seriously is a hero

(A new farmer in Panzhihua working on the farm, photographer @石磊)

The three words Panzhihua

It means the flower that is as bright as fire

Also remember the 60 years of dedication of Panzhihua people

60 years of daring to think and work hard

This is the beautiful hometown of Panzhihua people.

Why not?

The spiritual homeland of all Chinese people

(Panzhihua Fireworks Show, photographer @Five Hundred Thousand Gallons)

And this is

China's most punk industrial city

Iron-blooded and tender, stubborn and romantic

No matter the front is full of thorns or the sky is vast

Panzhihua's million heroes are in place

One word is

" Dry "
