Representative of China Carbon Industry Association: Since the founding of New China 70 years ago, China's steel industry has undergone earth-shaking changes, which has created brilliant achievements. 

First, in terms of crude steel production, in 1949, China's crude steel output was only 158,000 tons, reaching 128.5 million tons in 2000, becoming the world's largest steel producing country; breaking through 800 million tons in 2013; reaching 9.28 in 2018. 100 million tons, accounting for more than half of the world. 

Second, with technological innovation and technological advancement, the number of steel products has increased significantly, and major steel companies have reached the world's advanced level. 

Thirdly, the industrial concentration has been greatly improved, the level of environmental protection and energy conservation has been greatly improved, and new processes and intelligent manufacturing have been widely used. China's carbon industry, like the steel industry, has undergone tremendous changes in 70 years and has created glory. China has become a big carbon country.

Representative of China Coking Industry Association: From the 40 years of my work in Shougang, the changes in China's steel industry are mainly: 

First, the products are from nothing. From the production of "noodles" and "sleeve belts" (threads, wire rods and narrow belts), to the production of a full range of high-end sheet and pipe. 

Second, the scale has grown from small to large. China's crude steel output has increased from tens of millions of tons to more than 900 million tons, ranking first in the world for 23 consecutive years; the scale of the top 10 steel companies before the reform and opening up has increased from one million tons to 10 million tons. 

Third, the level of technical equipment is from low to high. The production operation is developed from the experience of the people to the automatic control by computer software. The volume of the blast furnace is increased from several hundred cubic meters to more than 5,000 cubic meters, and the process technology has reached the international advanced level. The fourth is from import to export. China relies on imports of most steel products to become a net exporter of steel. Fifth, the factory environment is from poor to excellent. In the past, the factories with heavy smoke and noise have turned into clean and beautiful garden-like factories, and the environmental quality is comparable to that of similar enterprises in developed countries.

Representative of China Ferroalloy Industry Association: I participated in the work in August 1982. I have witnessed tremendous changes in the steel industry since the beginning of the industry: 

First, the output of crude steel has achieved leap-forward growth. From 1982, the output of crude steel was more than 30 million tons, ranking second in the world after the Soviet Union, the United States and Japan. By the end of 2018, the country's crude steel output reached 928 million tons, accounting for more than half of the world's crude steel production, ranking the world. the first. 

The second is the change in the structure of the variety. With the development of China's economy and society and the adjustment and adjustment of the national economic structure, the steel products are developed from a single to diversified, and the proportion of plate and strip and the proportion of long products alternate, which better meets the needs of national construction and development. 

Third, the steel industry has developed from a small scale, serious environmental pollution to industrial scale, large-scale equipment, automation of operations, and clean production. 

 Fourth, the per capita steel consumption has increased significantly. 

Fifth, the nature of the enterprise has undergone major changes. Non-state-owned enterprises account for 60% of the total steel production, and the proportion has increased significantly.

Representative of China Waste Steel Application Association: 

The changes in the steel industry are mainly: 

First, quantitative change. In 1987, when I joined the work, the national crude steel output was less than 60 million tons, just in the price double-track system, and the state-owned materials were about 20 million tons. After more than 20 years of development, China's crude steel output has reached nearly 1 billion tons. In that year, Anshan Iron and Steel Co., Ltd. was the largest producer of crude steel, and its crude steel output was less than 7 million tons. Now there are many steel enterprises with crude steel output of more than 10 million tons. Baosteel's crude steel output has grown from 3 million tons in that year. It is now nearly 100 million tons. 

The second is qualitative change. In that year, China's high-grade steel pipes such as oil pipes and automobile plates all relied on imports; nowadays, high-grade automobile plates, high-strength rebars (2000 MPa), and aircraft steels can be produced in China. 

The third is the progress in engineering technology. In that year, the construction of a steel plant with a capacity of 3 million tons was a major project; today, the steel plant invested by private enterprises started with a capacity of 5 million tons. 

The fourth is the development of steelmaking technology. At that time, there were few advanced steelmaking technologies that China could draw. Now, 100% continuous casting technology, hot rolling technology, ESP (headless rolling technology), continuous electric furnace tapping and other technologies are numerous. 

Fifth, the indicators such as energy conservation and environmental protection, and per capita steel production have undergone earth-shaking changes.

Representative of China Metallurgical and Mining Enterprise Association: In the early 1990s, my deepest memory of the steel industry was the management experience of “simulating market accounting and implementing cost veto” in the whole country. The most intuitive impression of steel companies is that The gray-brown factory building, the high chimneys are carrying heavy smoke, the steel-making ironworkers wear helmets, and the large iron shovel is used to shovel the fire. Nowadays, the iron and steel enterprises have undergone earth-shaking changes. The factory buildings are clean and washable. From afar, they only see high chimneys but no smoke. Environmental protection, low carbon and intelligence have become the standards for the development of steel enterprises.
