HNZJ Heavy Industry Forging Co., Ltd. is China's leading large-scale isothermal die forging technology leader.
The company's main products are special forgings for EMU transmissions; offshore oil drilling platform leg racks and side tubes; high temperature and high pressure tee fittings for supercritical generator sets; power machinery forgings (shafts for motors, steam turbines, blowers, and water turbines); Metallurgical machinery forgings (rolls, core rods, main uranium and fan-shaped plates of the coiling machine); large gears; large mold steels (cold work, hot work, plastics); petroleum and petrochemicals (petrochemical pipe fittings, drilling platform lifting transmission systems) Forgings, etc.; ceramic machinery (presses) forgings; forgings for ships (stern shafts, crankshafts, cranks, etc.).
The company bases itself on senior technical personnel with majors in metallurgy, forging, heat treatment, etc., takes the research and development of new products as the forerunner, and takes reliable product operation, long life cycle, and high cost performance as its business goals.
The scientific research personnel of the company cooperated with CNOOC and Baosteel to successfully develop the special rack steel for offshore oil drilling platform (ASTM A517Ｑ) instead of imported, and provided TSC Ocean Group with high-strength and low-temperature resistant offshore drilling platform lifting transmission system forgings; for the second automobile The manufacturing plant produces high-life hot work die steel; organizes the production of high-performance blast furnace heat recovery turbine spindles for the Shaanxi Blower Plant; cooperates with Wuhan Iron and Steel to complete the overall survey quality process formulation and production application of large-section die steel. It solved the pre-hardening problem of the domestic 700mm large mold. Cooperated with Zhengzhou Machinery Research Institute to develop special forgings to replace imported EMU transmissions, and its products have been successfully installed in batches on Daqin Railway Freight heavy-duty EMUs. The development of these products has been fully affirmed by the market.
