However, high manganese steel lining plate is rarely used now. Although it has sufficient impact toughness, cold hardening of the surface when subjected to a certain impact, it is more hard and wear-resistant, cement raw material milling processing technology requirements are very high and the price is expensive.

In addition, the high manganese steel lining plate is prone to creep, extension and surface transformation, which will cause reverse bow deformation and can not achieve ideal work hardening. Now the high manganese steel lining plate has been gradually replaced by alloy steel lining plate and rubber lining plate.

The alloy steel lining plate is wear-resistant and impact resistant, and the reasonable alloy element formula makes the lining plate have good physical and chemical properties, and the service life is more than twice that of high manganese steel.
