Steel pretreatment line process refers to the steel surface (ie state) of raw materials before processing shot blasting and coated with a layer of protective primer process. Steel after pretreatment can improve the corrosion resistance of mechanical products and metal components to improve the fatigue resistance of the steel plate, extending its life; also can optimize the fabrication of the steel surface state is conducive to the CNC cutting machine cutting and precision blanking. In addition, regular shape, due to the processing of steel, it is conducive to the mechanical the rust and automation painting, so steel pretreatment can greatly improve the efficiency of the clean-up work, reduce the labor intensity of the clean-up work and environmental pollution.
In recent years, thanks to the programmable controller, the degree of automation equipment heavy a greater degree of improvement.
Workpiece conveyor system
1 Workpiece conveyor system frequency stepless speed, Industry both synchronous operation, but also independent action
2 Blasting Room roller conveyor equipped with a special material wear-resistant jacket
3 Plate chain conveyor "V" shaped structure, after painting steel plate short-term contact, in order to avoid the destruction of the paint film. Shot Blasting a workpiece height measurement using a photoelectric switch and brake motors, outdoors in the blast, anti-dust interference.
