Introduction of steel pretreatment line development application
Steel plate pretreatment line mainly consists of roller conveyor system, shot blasting machine, automatic paint spraying system, drying room, shot blasting and dust removal system, paint mist filtration system and electric control system, and can be extended with automatic loading and unloading system and preheating room.

Process advantages
Steel pretreatment line process refers to the steel before processing (i.e. raw material state) for surface shot blasting and rust removal and coated with a layer of protective primer processing. Steel after pretreatment can improve the corrosion resistance of mechanical products and metal components, improve the fatigue resistance of steel plates and prolong their service life; it can also optimize the state of steel surface process making, which is conducive to CNC cutting machine underfeed and drop. In addition, because the shape of steel is more regular before processing, it is conducive to mechanical descaling and automatic painting, so the use of steel pretreatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and pollution of the environment.

Application and Development
The domestic steel plate pretreatment line can clean steel plates of 5 meters wide, and common sections such as angles, channels and I-beams can be treated by the steel plate pretreatment line. In recent years, due to the use of programmable controller control, the degree of automation of the equipment has been improved to a greater extent. With the rapid progress of science and technology, computers and automatic measurement and control instruments are commonly used in the machinery manufacturing industry, and some functions that were impossible to achieve decades ago are now easy to achieve. The steel pretreatment line adopts temperature transmitters, rotary encoders and other components, the whole line computer monitoring, closed-circuit television monitoring, and can be configured according to user requirements automatic coding instrument and automatic bar code printing device
