Ductile cast / heat-resistant castings / Botou River casting professional manufacturers Botou River casting Foundry is mainly engaged in heat-resistant cast iron, ductile iron, gray iron castings, Confucianism and cast iron, steel castings, high silicon ductile iron parts, high chromium cast iron parts. There are special steel ingot molding, machine tools, wind power generation, shipbuilding, mining machinery, petroleum machinery, valves, metal tools and other industries. Botou River casting main products are sintered trolley, grate, stopped plates, cooling bed with straightening plates, skirts, ingot mold, column pipe, cast chassis, ductile iron slag slag pot, coking equipment, machine tools and other resistant castings Pouring hot wear-resistant castings can be combined, a box of pieces, greatly improving the process yield and productivity castings; heat-resistant castings Riser reasonable shape can be set in an ideal location, without typing, modulus, etc. constraints of traditional factors, reducing the internal defects of castings, the traditional casting methods can not produce similar positive and negative T-slots and other components, heat-resistant castings direct casting, greatly reducing the cost of production, and precision casting precision close Casting; ideal casting material. Ductile iron castings is a high strength material cash needs, widely applied to machinery manufacturing industry in the past, the use of performance reached in steel, its excellent performance, successfully applied to a part of the force casting complex, strength, toughness, resistance high wear resistance components. Ductile iron castings so greatly improved mechanical properties, especially to improve the ductility and toughness, ductile castings sources 50s of the 20th century. Ductile iron castings behind gray cast iron material is widely used. Strength steel for strength and ductile castings are comparable. Nodular cast has a higher yield strength, yield strength minimum of 40k. High-chromium alloy casting is much higher than the wear resistance, and much higher than the average white iron toughness, strength, but it also combines excellent resistance to high temperature and corrosion resistance.
