Application of oil-free compressed air in smelting process

In the smelting and production process, compressed air serves as a key power and process medium, and its quality directly affects equipment operation stability and product quality. The oil-free compressed air output by Granklin water-lubricated single-screw air compressor plays an important role in many aspects of smelting due to its high purity and non-oil pollution. Specific applications are as follows:

1. Pneumatic control and instrument drive

The precise operation of smelting equipment (such as blast furnace tuyere control valves, converter oxygen lance positioning devices, and electric furnace tilting systems) relies on pneumatic components to drive it. Oil-free compressed air can avoid the deposition of oil in pneumatic pipelines, prevent problems such as valve jams and delayed instrument response, ensure rapid and accurate execution of control instructions, and improve the automation level and operating accuracy of the smelting process.

2. Material conveying and mixing

The transportation of smelting raw materials (such as ore, coal powder, flux) and the stirring of the molten bath are often achieved by compressed air. Oil-free compressed air avoids mixing of oil and raw materials, prevents blockage of transmission pipes or introduction of impurities during stirring, ensures accurate material ratio, promotes uniform reaction in the furnace, and improves smelting efficiency and metal recovery rate.

3. Combustion control and oxygen supply

Combustion oxygen supply for blast furnace hot stoves, converter top-blowing oxygen lances and other equipment requires a stable gas source. Oil-free compressed air ensures that oxygen purity is not affected by oil pollution, avoids incomplete combustion or unstable flame, optimizes fuel utilization, reduces energy consumption, and at the same time reduces the formation of harmful substances in flue gas, which meets environmental protection requirements.

4. Dust removal and environmental protection treatment

Smelting flue gas needs to be purified by bag dust collectors and other equipment. When oil-free compressed air is used for backblowing and dust removal, it can prevent oil stains from adhering to the dust removal bag, extend the service life of the bag, and reduce the maintenance frequency; at the same time, the pure air source ensures the backblowing effect, improves flue gas purification efficiency, and helps enterprises meet environmental protection emission standards.

The following are general guidance and suggestions: Determine the replacement cycle according to the type of oil Minite oil: Replacement cycle: It is recommended to replace it every 3 to […]

What is the average factory pressure?

In industrial production, the air pressure required by the factory is usually determined based on process requirements. Common ranges are as follows: 1. Basic air pressure demand The air pressure demand in most light industrial scenarios (such as packaging, spraying, and pneumatic tool drives) is concentrated at 0.6-0.8 megabytes…

What is the dew point requirement for compressed air for sterile preparations

Compressed air dew point requirements and solutions in the production of sterile preparations 1. Definition and importance of dew point Dew point refers to the temperature at which the air cools until water vapor reaches saturation. The lower the dew point, the less moisture content in the air. In sterile…

Do you need to refuel the oil-free air compressor?

The oil-free air compressor usually does not require refueling during normal operation because it uses oil-free water lubrication technology, mainly using pure water for lubrication, rather than traditional lubricating oil. This technology enables an oil-free air compressor to generate oil-free compressed air. However, in some special cases, it may be necessary to add lubricating oil […]
