Metallurgical industry refers to the mining, cleaning, sintering of metal ore, smelting and processing into metal materials.

It is divided into: 

(1) ferrous metallurgy industry, that is, the industrial sector producing iron, chromium, manganese and their alloys. It mainly provides raw materials for modern industry, transportation, infrastructure and military equipment;

(2) The nonferrous metallurgy industry refers to the metal refining industry which produces non ferrous metals, such as copper smelting industry, aluminum industry, lead and zinc industry, nickel cobalt industry, tin smelting industry, precious metal industry, rare metal industry, etc.

Since the 1980s, the scale of development of the iron and steel industry has been significantly expanded. In the 1990s, the international competition has become increasingly fierce. Most enterprises have shifted their development focus to reducing consumption, reducing costs, increasing varieties, improving production quality and environmental protection.

The traditional metallurgical production process is operated in a cold environment, and has been gradually improved in recent years. The iron and steel industry has made obvious progress, mainly reflected in the production process, process optimization and quality improvement. Domestic. In recent years, the state has issued relevant macro-control policies to manage and support the metallurgical industry, with initial results.

Due to the large scale of production in the iron and steel industry, the impact of low-level inspection construction is very poor. The implementation of these policies effectively controls the low-level repeated construction, strictly forbids "local bar steel" and other inferior products to enter the steel market, so as to avoid adverse impact on the market environment. It not only purifies the steel market, but also effectively improves the standardization and rationalization of the steel market.

At the same time, the consumption structure of various sectors of society is also upgrading with the development of economy, and the process of urbanization is accelerating. This social background has laid a good foundation for the development of iron and steel enterprises. In recent years, the strategy of developing the western region and revitalizing the old industrial base in Northeast China has been launched gradually, which has been highly valued by all levels of society. At the same time, it has brought new opportunities for the development of iron and steel metallurgy industry.
