In steel companies, compressed air accounts for a large proportion of all energy consumption (about 5%-15% of total energy consumption). In steel companies, compressed air is widely used as an energy medium. Strict management and technical improvement should pay more attention to production, transportation and use to adapt to the situation of energy saving and emission reduction.

The energy saving potential and countermeasures of compressed air system in steel enterprises in peer exchange are discussed. The energy-saving technologies, power market theory, data mining, data simulation and forecasting of compressed air systems in iron and steel enterprises are summarized.

1. Configuration of air compressor station in iron and steel enterprises:

The types of air compressor stations in steel companies generally include centrifugal air compressor stations, screw air compressor stations and hybrid air compressor stations (centrifugal air compressor stations and screw air compressor stations). Some steel companies are phasing out and updating piston air compressors.

The centrifuge air compressor station is generally equipped with 2 to 9 centrifuges, usually with a displacement of 100 m3/min to 300 m3/min. According to the production needs, it is generally set to 1.3Mpa and other exhaust pressures, of which 0.38MPa and 0.5Mpa. For air-making machines for steel making and continuous casting, 08MPa iS A power / instrument air compressor, 1.3Mpa for coal injection blast furnace. Air compressor.

The screw compressor air compressor station is generally equipped with 2-8 screw machines, most of which have a displacement of less than 10 m3/min-40 m3/min. The screw compressor is mainly used as an auxiliary air source for the centrifugal air compressor.

According to whether the air compressor station is connected to the network, it can be divided into distributed layout and centralized network layout. With the improvement of the operation stability and control management level of air compressor equipment, in the new steel enterprises, the old decentralized steel enterprises generally adopt centralized networking, and many enterprises plan to establish networking between air compressor stations or power distribution. Regional network.

2. Main uses and characteristics of compressed air:

The use of compressed air in steel companies is included in all production processes. Its main uses can be divided into: sintering pneumatic conveying, blast furnace blowing, continuous casting steam spray cooling, converter bottom blowing, steel belt surface blowing, various pneumatic instrument valves, air motors, pulse bag filters.

The distribution of compressed air in ironmaking equipment can be divided into a sintering zone, a raw material zone, a coke oven zone and a blast furnace zone. The compressed air in the steelmaking unit is mainly used for continuous casting, converter pneumatics and purging, and for aerosol cooling for continuous casting. The compressed air in the hot rolling mill is mainly used for rolling mill and furnace pneumatic equipment as well as cold rolling purge. The unit's compressed air is mainly used for strip cleaning, pickling, continuous winding, pneumatic equipment and hot-dip galvanizing equipment.

The application of compressors in the steel industry.

Generally speaking, the compressed air generated by the air compressor in the compressed air system of the steel enterprise is treated by the cold dryer to reduce the pressure dew point to 3-5C, providing the user with the power (normal) compressed air; or by adsorption. After the dryer is processed, the compressed air is treated by a dryer. e Reduce the water content to a pressure dew point below -20 °C to remove dust particles with a dust content of less than 5 m and a dust content of less than 5 mg/m. The oil content is less than 1 mg/m3 and is used as compressed air for the meter.
