Shandong xianjin mining equipment Co., Ltd specialized in the production chain, rigging and other products, following a brief high intensity ring chain production process key points: Processing Technology: active thickness data and leading technology, shot peening, extrusion, cold extrusion, roller chain plate high-speed repeatedly bright punching, riveting, four double-sided printing and other new technology, in the industry began to adopt, which improves the quality of the product in a certain extent. In the chain of production equipment: China has successively developed high-speed driving chain has Chinese characteristics of successful cutting machine, high speed pin machine, high speed winding machine, roller five position cold extrusion machine, chain installation active line, high speed chain installation machine, multi station flat top chain driving molding installation line and a series of advanced, efficient, useful for chain equipment, instead of some traditional chain of production equipment, the narrowing of China with foreign leading chain plane between the chain equipment distance. In the heat treatment: in recent years, the heat treatment technology and equipment of our country chain product forward greatly, some raw material selection of nitrogen (or nitrogen hydrogen mixture) annealing furnace maintenance; chain parts are usually selected mesh belt furnace for heat treatment of quenching and tempering, quality is stable, the discrete degree control in 3 - 4 degrees; the new technology of strengthening and toughening treatment, chain parts chromizing, boronizing, isothermal quenching and quenching medium "with water replacing oil", also have the use of.
