Yantai Zhongtuo Alloy Steel Casting Co., Ltd is engaged in producing all kinds of high-temperature cast tube, deformed piece, and erosion proof, wear well and heat-resisting alloy by centrifugal casting, lost pattern casting and precision casting. The company is especially good at producing large-bore spun cast pipe (max diameter 2, 000mm) and large static cast piece (max weight 5, 000kg). Our products are widely applied in petrifaction, metallurgy, power, building material, coal, ship, medicine, environment protection, nuclear and paper-making machinery industry.This company was transformed from a Shandong Jining based state-owned enterprise, which had dealt with special alloy steel casting for nearly 30 years. Now the company has nearly 100 arc furnaces, medium frequency induction furnaces, centrifugal casting machines, lost pattern casting production lines, large imported direct reading spectrometers, and all kinds of machine work lathes, boring machines and milling machines. Our technicians and backbone workers have accumulated rich work experience and casting technology, and developed ZTHJ serial erosion proof and wear well alloy with scientific and research institutes, which are applied in sinking roll and permanent roll of sheet-galvanizing line, aluminum plating line and aluminum-zinc-silicon line, whose life is 5 times that of common products.With advanced technology, special technique and strict quality management, the company creates first-class products and serves customers honestly.
