1.The surface of the casting is smooth and has good appearance quality, reduces the adverse effects of appearance defects, and is beneficial to improve the wear resistance; because the sand mold is always kept in a vacuum state, the cavity is not easily deformed, which is beneficial to filling the mold with molten metal, and the contour of the casting is clear and the size is accurate. Less processing allowance;
2.No binders and additives, no sand mixing equipment, save raw materials and power, reduce environmental pollution, reduce operation and maintenance costs, and be environmentally friendly;
3.The old sand can be recycled up to 95%, which solves the problem of waste sand disposal;
4.V-method casting metal has good fluidity, strong filling capacity, slow cooling of molten metal in the cavity, which is conducive to feeding, the riser of the casting can be reduced, the metal utilization rate is high, and the process yield is high;
5.V-method casting sand molds have high compactness and can be poured at low temperature to refine the grains of wear-resistant castings and have good wear resistance; external cooling iron can be added to refine the grains of the wear-resistant parts of wear-resistant castings and improve wear resistance ;
6.High degree of mechanization, improved working conditions, reduced labor intensity of workers, and good working environment.
Because the V-method casting process produces wear-resistant castings with the above six advantages, it occupies an important position in the production of wear-resistant castings in my country and the world.
Shanvim Industry (Jinhua) Co., Ltd., established in 1991. The company is a wear-resistant parts casting enterprise. The main products are the wear-resistant parts such as mantle, bowl liner, jaw plate, hammer, blow bar, ball mill liner, etc.. There are medium and high , Ultra-high manganese steel, medium carbon alloy steel , low, medium and high chromium cast iron materials, etc.. It mainly produces and supplies wear-resistant castings for mining, cement, building materials, infrastructure construction, electric power, sands and gravel aggregates, machinery manufacturing and other industries.
