The role of ferrosilicon 72 in the steelmaking industry

 Ferroalloy is one of the important raw materials in the iron and steel industry. The output, quality and variety of ferroalloy are directly related to the quality of steel and its products. In a certain sense, without ferroalloys, there would be no steel and its products.

Our country's ferroalloy industry develops with the development of iron and steel industry. my country's steel output in the early days of the founding of the People's Republic of China has grown from 158,000 tons to 200 million tons now. The total output of ferroalloys including 72 ferrosilicon has grown from an annual output of about 900 tons in 1949 to 6 million tons now, accounting for about 22-25% of the world's total output, with exports of more than 1 million tons, earning more than 800 million US dollars . At present, my country has become the world's largest producer and exporter of ferroalloys. With such a large output of ferroalloys, 72 ferrosilicon will consume nearly 2 million tons of steel scraps and related materials every year.

Since the "Seventh Five-Year Plan", the development speed of my country's 72 ferrosilicon alloy industry has exceeded the development speed of the iron and steel industry. In addition to domestic consumption and export, the output of ferroalloy has a lot of wealth, and the backlog of inventory and exports have decreased every year. , The cost is too high, the quality does not meet the international requirements, the ingredients do not meet the quality standards, the disorderly competition between enterprises, etc., are not conducive to the ferroalloy industry to reduce consumption, optimize the process to improve quality, reduce costs, improve efficiency, and expand the market. Purpose.

According to the production and current situation of ferroalloys, the amount of steel scraps used to process 72 ferrosilicon alloys in my country is about 2 million tons each year.
