Chengde Rongmao Cast Steel Co.,Ltd

The company is located in Xiaoxindian, Yuerya, Kuancheng Manchu County, Chengde of Hebei province and the plant is next to Chengqin Chuhai Road. Rong Mao was founded in 1980s, and it was extended to a professional casting steel enterprise in 2003. For over ten years, it has produced multiple products such as Austempered Ductile Iron (ADI) grinding ball, high-chromium alloy combined hammer, ball mill liner, various models of jaw crusher tooth plate, hammer crusher liner, castor-oil plant section, and all kinds of high manganese steel castings.

1.High wear and impact resistance

With scientific and reasonable formulation of alloy elements, the high manganese steel liner is multivariate micro-alloying on the basis of the original high-manganese steel, then it has good physical and chemical properties, such as the hardness HRC52-56, the impact toughness value larger than 150J, using life is more than twice as high manganese steel. So it can tolerate a huge impact strength. In a long-term work it can keep lining surface state so ensure a stable increase of more than 5% of production.

2. High strength, high toughness

By using the special quenching medium agent with thermal stability in the quenching process, high manganese steel liners combine high strength, high hardness and high toughness perfectly, which can satisfy high wear resistance and high impact loads process requirements.

3.High cost-effective, strong adaptability

Through the reasonable alloying elements and advanced process of our company, high manganese steel liner has a high quenching hardness, high toughness characteristics. So that it not only has good wear resistance, but also shows excellent price compared with the ordinary liner. It can adapt to mine wet grinding, dry grinding, mixing mill and etc. High manganese steel liners use advanced heat treatment process and change the height of ball mill’s peak, trough. These all help improve grinding rate of ball mill and increase the 20% of machine-hour capacity.
