Steel pretreatment line – Longfa

The steel pretreatment line process refers to the processing technology in which the steel is subjected to surface shot blasting and derusting before processing (that is, the raw material state) and coated with a layer of protective primer. Pretreatment of steel can improve the corrosion resistance of mechanical products and metal components, improve the fatigue resistance of steel plates, and prolong their service life; at the same time, it can also optimize the production state of steel surface technology, 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 environmental pollution.
