（1）要求衬板具有良好的耐磨性能。
(1) The liner is required to have good wear resistance.
高耐磨、耐冲击双介质淬火中合金钢衬板经科学合理的合金元素配方，使该衬板具有良好的理化性能，硬度HRC45－55以上，冲击韧性值25J以上，使用寿命是高锰钢的2倍以上。能够承受巨大的冲击力度。在工作中能长期保持衬板的表面形状，以保证磨机稳定提高5%以上的产量。
High wear-resistant and impact-resistant dual-medium quenched alloy steel liner has good physical and chemical properties, hardness HRC 45-55, impact toughness value more than 25J and service life more than twice that of high manganese steel through scientific and reasonable alloy element formulation. Can withstand tremendous impact. The surface shape of liner can be maintained for a long time in order to ensure that the mill can steadily increase the output by more than 5%.
（2）高强度、高韧性。
(2) High strength and toughness.
在衬板淬火过程中，采用热稳定性能好的专用双介质淬火剂为介质，使产品达到高强度、高硬度和高韧性的配合，以满足了耐磨损的工艺要求。
In the quenching process of liner, the special dual-medium quenchant with good thermal stability is used as the medium, so that the product can achieve the combination of high strength, high hardness and high toughness to meet the technological requirements of wear resistance.
（3）高性价比、适应性能强经先进的双介质淬火工艺处理，它具有淬火硬度高、韧性值高的特点，使该衬板具有良好的耐磨性能，高锰钢衬板相比，中合金双介质淬火中合金钢球磨机衬板表现出了较好的性价比。能适应矿山湿磨、干磨、混合磨等。

(3) High performance-price ratio and strong adaptability are treated by advanced dual-medium changyi.71ix.comhuganqi.37ix.com.cnkongzhigui.37ix.com.cncewen.37ix.com.cnjiedi.37ix.com.cn

xiaoxie.37ix.com.cnquenching process. It has the characteristics of high hardness and high toughness, which makes the liner have good wear resistance. Compared with high manganese steel liner, the liner of alloy ball mill in medium alloy dual-medium quenching shows better performance-price ratio. It can adapt to wet grinding, dry grinding and mixed grinding in mines.
