The steel plate pretreatment line is mainly composed of roller conveyor system, preheating chamber, shot blasting cleaning machine, automatic paint spraying system, drying room, shot blasting dust removal system, paint mist filtering system and electric control system, and can be extended to automatic loading and unloading. material system and typing. The steel pretreatment line process refers to the processing technology in which the surface of the steel is shot blasted and rust removed and coated with a protective primer before processing (that is, the raw material state). Pretreatment of steel can improve the corrosion resistance of mechanical products and metal components, improve the fatigue resistance of steel plates, and prolong its service life; at the same time, it can also optimize the production state of the surface of the steel, which is conducive to CNC cutting machine blanking and precision blanking. In addition, since the shape of the steel before processing is relatively regular, it is conducive to mechanical rust removal and automatic painting. Therefore, the use of steel pretreatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and reduce environmental pollution. At the same time, the processing line can also be used for shot blasting pretreatment for various types of steel.
