What links in the metallurgical industry to use air compressors

2026-04-14Views:

In the metallurgical industry, air compressors play a vital role in many key links. The following is a detailed summary of the application of air compressors in the metallurgical industry:

1. Metal smelting process

  • ore sintering, ironmaking and steelmaking in the main smelting process from ore to steel, the air compressor needs to run safely, reliably and smoothly for a long time to meet various performance and working conditions. These links usually require the air compressor to have good controllability, reasonable operation mode and local start and stop, commissioning and normal or accident detection, control regulation and protection measures.
  • Opening of smelting furnace doors, lifting, lifting and casting of ladles containing liquid non-ferrous metals: These mechanical actions require compressed air to complete. The pressure requirement of compressed air is generally 0.6~0.7MPa, the quality standard is not high, but the stability requirement is strong.

2. Finishing process

  • compressed air for CNC machine tools or machining centers: Finishing is usually carried out on CNC machine tools. The tooling and fixtures of these machine tools, the loading and unloading of tools, etc. are all completed by the pressure of compressed air. Although the compressed air consumption of CNC machine tools is not very large (about 0.5m & sup3;/min), it has higher requirements for the stability of pressure, and the general pressure requirement is 0.6~0.7MPa.

3. Appearance processing process

  • gas consumption of spraying equipment in the appearance treatment stage of metal smelters, electrostatic spraying is generally used. The gas consumption of spraying equipment is relatively large, and there are certain requirements for the quality of compressed air, but it is usually lower than the quality requirements of instrument gas.

4. Instrument gas

  • control and detection of various instruments in metallurgical plants: There are still some instruments in the metallurgical plant that need to use compressed air for control and testing. These instruments have high requirements on the quality of compressed air, but the amount of air is relatively small.

5. Other Applications

  • the production line of the bundling machine packaging and rolling steel continuous binding of the cable plate. These links also need to use the compressed air provided by the air compressor to complete the specific mechanical action and process.

6. Specific Process Requirements

  • specific processes in non-ferrous metal smelting for example, in the copper smelting process, it is necessary to blow compressed air into the melting furnace through a graphite tube to oxidize the impurities in the melt. In this process, the compressed air provided by the air compressor has a direct impact on the smelting effect.

Air compressor type selection

  • screw air compressor: Because the screw air compressor has low vibration, low noise and high efficiency, it can be installed on the chassis together with auxiliary equipment to form a complete air compressor box-type unit with power and control as one, so it is widely used in the metallurgical industry.

In summary, the application of air compressors in the metallurgical industry is very extensive, almost throughout the entire smelting and processing process. From ore sintering, iron and steel making to finishing, appearance treatment and instrument gas and other links need to use the compressed air provided by the air compressor to complete the specific process requirements and mechanical actions.

    Dental medical oil-free air compressor for sale

    Medical air compressor to use dental electric oil-free air compressor, ordinary air compressor compressed gas, containing a large amount of moisture and other relative impurities, but also through mechanical compression, mechanical lubricating oil may also be mixed in the compressed air. Therefore, the water-lubricated oil-free air compressor is a more appropriate consideration. The compressed air produced by it is treated and relatively pure. Most of the two medical air compressors are indoors, and the medical environment needs no noise pollution, so water-lubricated oil-free air compressors are used more.
