| high toughness durable and stable High Manganese lining plate |
Characteristics of lining plate:
1. The high wear and impact resistance
Double quenching medium alloy steel by scientific and reasonable alloy element formulation, the lning plate has good physicochemical properties, hardness hrc45 - more than 55, the impact toughness value above 25J, the service life is 2 times more than that of high manganese steel. Able to withstand the tremendous impact. In the work can maintain the surface shape of the lining board for a long time, in order to ensure the stability of the mill to improve more than 5% of the output.
2. The high strength, high toughness in lining plate in hardening process by good thermal stability performance of the special double quenching agent as the medium, so that products meet the high strength, high hardness and high toughness, to meet the process requirements of wear resistant
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

3. high performance, strong adaptability
Processing by advanced dual medium quenching process. It has high quenching hardness, toughness, high and the lining plate has good wear resistance, high manganese steel liner compared, alloy double quenching medium alloy steel ball mill lining plate superior price. Can adapt to the wet grinding, dry grinding, mixed grinding, etc..
Ball mill lining plate is used to protect the cylinder body, so that the cylinder body from the direct impact and friction of the grinding body and materials, but also can use different forms of lining plate to adjust the motion state of the grinding body, to enhance the grinding effect of the grinding body on the material, help to improve the grinding efficiency of the mill, increase output, reduce metal consumption.
