Oxygen air compressor plays a vital role in the metallurgical industry. It is mainly used to produce high-purity industrial oxygen and supply the oxygen demand in metal processing processes such as smelting and steelmaking. The following are the main functions and processes of oxygen air compressors in the metallurgical industry:
1. Provide oxygen supply:
In the metallurgical process, oxygen is an important chemical component, especially in steelmaking, aluminum smelting, copper smelting, etc. High-purity oxygen can accelerate chemical reactions, improve production efficiency and reduce energy consumption.
2. Oxygen combustion:
In blast furnaces, converters and other smelting equipment, oxygen is injected into the combustion area to improve the combustion temperature and promote the reduction reaction of iron or other metal ores. This can melt metals faster and reduce production time.
3. Improve product quality:
High-purity oxygen can effectively remove impurities in metals, such as carbon, sulfur and phosphorus. If these impurities are not effectively removed, they will affect the quality and physical performance of the final product.
4. Reduce energy consumption:
In the metallurgical process, the use of oxygen to help combustion can significantly reduce fuel consumption. This not only reduces energy costs, but also reduces the emissions of greenhouse gases such as carbon dioxide.
5. The working process of oxygen air compressor:
• Air compression: First of all, the oxygen air compressor inhales air from the atmosphere and compresses the air to a higher pressure through the compressor.
• Air purification: The compressed air needs to be purified through cooling, filtration and other steps to remove moisture, carbon dioxide and other impurities.
• Air separation: The purified air separates oxygen and nitrogen through a low-temperature separation process (usually using the cryogenic method). Among them, the oxygen will be further purified to the required purity (for example, 99.5% or higher).
• Oxygen compression and storage: After compression, high-purity oxygen is stored in high-pressure storage tanks and ready to be supplied to the metallurgical production line at any time.
6. Application examples of metallurgy:
• Converter steelmaking: The high-purity oxygen produced by the oxygen air compressor is directly injected into the converter to promote the reaction of carbon and oxygen to generate carbon dioxide, thus removing the carbon content in the steel.
• Blast furnace ironmaking: In a blast furnace, oxygen is used to help burn coke and raise the temperature so that iron ore can be reduced to iron.
Summary:
Oxygen air compressor is an indispensable equipment in the metallurgical industry. By providing high-purity oxygen, it helps to improve smelting efficiency, reduce energy consumption and improve metal quality, thus playing a key role in the metallurgical industry.
