Gases In Metallurgy Industry
In the metallurgical industry, carbon monoxide is used as a deoxidizer. The main application areas of CO are the chemical industry and the metallurgical industry. CO is used as a deoxidizer to reduce iron oxides in steelmaking blast furnaces. The mixture of CO and hydrogen, namely syngas, can also be used to produce some special steels. For example, direct reduction of iron ore can produce sponge iron.
The application of nitrogen in steel plants is mainly used as a protective gas, such as steel rolling, galvanizing, heat treatment, etc., all use nitrogen as a protective gas. The blowing and protection of argon is an important way to improve the quality of steel. Oxygen, nitrogen and argon are indispensable industrial gases for steelmaking enterprises.
The steel industry and air separation gas are interdependent and mutually reinforcing. The growth of the steel industry has driven the development of the gas industry. The development of the gas industry has promoted the steel industry, and the relationship between the two is inseparable.
