Steel plate pretreatment line

The steel pretreatment line process refers to the process of blasting and derusting the surface of the steel before processing (that is, the state of the raw material) and applying a layer of protective primer. The pretreatment of steel can improve the corrosion resistance of mechanical products and metal components, improve the fatigue resistance of steel plates, and extend its service life. At the same time, it can also optimize the state of the steel surface process, which is conducive to CNC cutting and blanking. In addition, because the shape of the steel before processing is relatively regular, which is conducive to mechanical rust removal and automatic painting, the use of steel pretreatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and environmental pollution.
