The company adopts advanced lost foam casting and metal mold casting processes. It possesses two 2-ton double-rectifier series-connected inverter medium-frequency steel-shell electric furnaces, complete with vacuum suction, sand processing, high-frequency vibrating compaction equipment, two 10-ton heat treatment furnaces, automatic mold cutting and drying equipment, a large-scale dust removal system with a capacity of 30,000 cubic meters per hour, and laboratory equipment including a carbon and sulfur combined analyzer.
The wear-resistant steel balls and steel forgings are cast and molded from metal molds, featuring high hardness and wear resistance. The steel balls exhibit high grinding efficiency, while the steel forgings achieve fine grinding fineness. The company offers a complete range of specifications for steel balls and forgings, meeting the wear resistance requirements under different working conditions.
