Henan Chalco is the largest and most productive Anode steel claws manufacturer in China, a member of China Quality Management Association, a member of Henan Foundry Association, and passed ISO9001 international quality management system certification in 2002. The company has the most advanced complete set of equipment for the production of Anode steel claws-the lost foam casting production line. The types of Anode steel claws are two-claw, three-claw, four-claw, six-claw, and eight-claw. Equipped with physical and chemical measurement and rapid analysis laboratory in front of the furnace, using electric arc furnace (or intermediate frequency furnace) and rare earth refining to ensure that the gas content and impurities in the molten steel are reduced to a minimum, so as to obtain better electrical conductivity. The advanced dry sand solid negative pressure (lost foam) green casting process is adopted to make Anode steel claws qualified in size, smooth surface, tight internal organization, and free of blisters, slag inclusions, cracks, pores, shrinkage and other defects. A large-tonnage self-controlled reverberatory furnace is used for aging treatment, and a trolley-type shot blasting machine is used for surface strengthening treatment, especially the Anode steel claws used parts are all exposed to metal luster. The double-sided combined special milling machine is used for mechanical processing, with high processing accuracy and good quality. For the control of harmful elements, the company’s internal control standards are implemented, that is, S≤0.03%, P≤0.035%, and harmful elements <0.7%, which is stricter than the national standard. Through the use of advanced lost foam casting technology and equipment, users can achieve cleanup-free before use, safe and efficient, and are trusted and praised by users
