Manganese steel mill liners

Manganese steel mill liners manufacturer

Manganese steel is widely used in casting kinds of mill liners. This is used for grid liners and generally smaller mills. Its great advantage is that it works hardens under stress, yet the substrate remains tough and can withstand extreme impact without fracture. Its primary disadvantage is that it spreads with impact, so solid liners begin to squeeze together and become extremely difficult to remove, and can damage a mill shell if the stress is allowed to build up to an extreme level.

MGS Casting is one of the largest manganese steel mill liners manufacturer in China. In most cases, we have manufactured many types of mill liners and also stock some common manganese mill liners. In some cases, MGS Casting has even improved the conventional design of those manganese mill liners to enhance durability and performance.

Benefits

• High strength & 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.
• 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 processes and change the height of the ball mill’s peak, trough. These all help improve the grinding rate of ball mill and increase the 20% of machine-hour capacity.
• High wear and impact resistance. With the 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 long-term work it can keep lining surface state so ensure a stable increase of more than 5% of production.
