High strength casting products wear-resistant cast steel machinery parts and dual-phase stainless steel, gray cast iron, ductile iron made of various parts are mainly used in pumps, valves, construction machinery and other equipment, construction area of 7000 square meters, plant area 19000 square meters. Existing staff 150 people, the annual output of 4000 tons. Problems to be solved: wind power castings need 12 low-temperature (-40℃ forging and casting) impact energy, casting performance and material requirements are extremely strict. The qualified rate of wind power castings is 75%, the qualified rate is low, and the production efficiency is low. It is necessary to develop cooperation with institutions of higher learning and scientific research institutions to increase casting qualification rate from 75% to 95%, effectively improve product qualification rate, improve product quality and expand market share. The main products are bearings, tile boxes, building fasteners and so on. Our products are mainly exported to Shanxi, Henan, Guangdong, Guangxi and Northeast China, with an annual output of 3,000 tons. Adopting advanced casting molding technology can reduce the production cost, improve the rate of finished products, improve the qualified rate of products and increase the added value of products.
