High Manganese Steel casting mill liner plate for grinding
SCMN11 mill liner plate in general refers to a kind of casting steel with the Mn content at 11~22%, the carbon content at 0.9~1.5%, mostly higher than 1.0%. Under low impact load, can achieve HB300~400, Under high impact load, can achieve HB500~800.Different impact load, the surface hardening layer depth can be up to 10~20 mm. High hardness of hardening layer can resist the wear of grinding media. Under the condition of strong impact abrasive wear, high manganese steel has excellent anti-wear performance, so it is widely used in mining, aggregates, coal industries as wear-resistant parts.
SCMN11 Mill liners need to protect the mill shell from damages due to wear and transmit the energy from the rotating mill to the ball charge.
The rules that guide the design of a liner depend on the grinding mechanisms required for the specific mill. They can be classified either as impact/cataracting for very coarse to coarse grinding, cascading for coarse to medium grinding or attrition for medium to fine grinding.
In any case the design of a liner is a compromise between lifetime and grinding efficiency.
Note : Depending upon the various application, we propose suitable profile with appropriate alloy ranging from 12 to 25% .

China's current general wear resistant material series of high manganese steel series: such as high manganese steel (ZGMN13),
High manganese alloy (Zgmn13Cr2MoR), ultra-high manganese alloy (Zgmn18Cr2MoR), etc.
High manganese steel (such as ZGMN13) under severe impact or contact stress, its surface will rapidly harden, while the core still maintains a strong toughness, hard outside and tough inside both wear resistance and impact resistance.And the heavier the impact on the surface, the more full the surface hardening, the better the wear resistance.Because the hardness of high manganese steel itself is very low (HB170-230), the wear resistance is extremely limited before hardening. If the surface of high manganese steel is not enough to bear the impact force, the surface can not be fully hardened (after full hardening, the surface hardness can reach HB550 or below, otherwise), then the wear resistance will not play a role, and the wear resistance will not be shown.
Because Zgmn18Cr2 contains more manganese, the surface hardening can be more sufficient, so more wear-resistant.
Of course, ZGMN18Cr2 series (such as ZGMN18Cr2MORE) is also more expensive than ZGMN13 series.
The main material in the hammer of high manganese steel is high manganese steel (Mn13,Mn13Cr2 and Mn18Cr2). With the continuous development of wear-resistant materials, the high toughness of high manganese steel is incomparable to other wear-resistant materials.v
