Continuous Through Type Steel Plate Shot Blasting Machine Steel Plate Pretreatment Line
General introduction
Steel Plate and Steel Products Pre-Treatment refers to that before processing, the surface of the steel products is blast to remove the rust and coated with undercoat. The pre-treatment can improve the anti-erosion of mechanical products, metal structural parts and improve the anti-fatigue of steel plates to prolong its life. The surface of steel plates will be optimized for processing and numerical controlled incision and precise blanking. Besides, before treatment, the shape of steel products is formulated, which is in favor of rust removing and automatic coating, so pre-treatment for steel products can improve the efficiency of cleaning and minimize labor and pollution.
In recent years, the automation of the equipment has developed a great deal due to adopting programmable digit controller.
