Application of oxygen air compressor in the steel industry

In the iron and steel industry, oxygen air compressors play a key role, mainly used to provide high-purity oxygen to improve the efficiency and quality of ironmaking and steelmaking processes.

1.Blast furnace ironmaking

Improve combustion efficiency:In a blast furnace, oxygen is used to improve the combustion efficiency of fuels (such as coke). Increasing the oxygen content can make the fuel burn more fully, thus generating higher temperatures and improving the reduction efficiency of iron ore.

Reduce coke consumption:The use of high-purity oxygen can significantly reduce the demand for coke in the blast furnace ironmaking process, reduce production costs, and reduce carbon dioxide emissions.

2. Steelmaking in a converter

Remove impurities:In the process of converter steelmaking, oxygen spraying is used to remove carbon, silicon, phosphorus and other impurities in iron water. High-purity oxygen can accelerate the oxidation reaction of impurities and improve the purity of steel.

Improve the reaction speed:Oxygen converter steelmaking method (such as BOF method) uses high-purity oxygen to accelerate carbon-oxygen reaction, quickly remove impurities in iron water, and improve production efficiency and steel quality.

3. Electric arc furnace steelmaking

Enhanced combustion:In the process of electric arc furnace steelmaking, oxygen combustion technology can improve the temperature in the furnace, accelerate the melting speed, and save electricity.

Melting of scrap steel:Oxygen is used in the electric arc furnace to improve the melting speed of scrap steel, optimize the recycling and reuse of scrap steel, and improve the production efficiency of steel.

4. Melting scrap steel

Aeration of scrap steel:In the smelting process of scrap steel, the introduction of oxygen helps to improve the melting speed, reduce energy consumption and improve production efficiency.

5. Environmental protection and emission reduction

Reduce pollution:The use of oxygen combustion technology can reduce harmful components in waste gas emissions during ironmaking and steelmaking, and effectively reduce air pollution.

Energy conservation and emission reduction:The efficient use of oxygen can reduce fossil fuel consumption, thus reducing greenhouse gas emissions and promoting the green transformation of the steel industry.

6. Production of special steel

Control alloy composition:In the production of special steel, oxygen is used to accurately control the alloy composition, remove impurities through refining, and improve the characteristics of steel.

7. Oxygen blowing technology

Rapid warming:Oxygen blowing technology can be used to quickly raise the temperature of blast furnaces and converters, speed up the smelting process, and improve production efficiency.

Energy saving:By increasing the oxygen content, the demand for electricity and fuel in the smelting process can be significantly reduced, and the energy consumption can be reduced.

Advantages:

Efficiency improvement: improve the combustion and smelting efficiency, and shorten the smelting time.

Cost reduction: reduce coke and electricity consumption, and reduce production costs.

Environmental benefits: Reduce carbon dioxide and harmful gas emissions.

The application of oxygen air compressor in the iron and steel industry not only improves production efficiency and product quality, but also promotes the development of green environmental protection technology and becomes an indispensable and important part of modern steel production.
