当以粉碎为主时，要求衬板对研磨体的推举能力较强，同时衬板应具有良好的抗冲击性能，高锰钢ZGMn13有足够的抗冲击韧性，但不耐磨且易变形，大多数已改用双介质淬火工艺中合金钢或铬钼合金钢衬板。
When grinding is the main method, it is required that the liner has a strong ability to push the abrasive body, and that the liner should have good impact resistance. The high manganese steel ZGMn13 has sufficient impact toughness, but it is not wearable and easy to deform. Most of the liners have been changed to alloy steel or chromium-molybdenum alloy steel in dual-medium quenching process.
比较几种耐磨材料，以双介质淬火工艺中合金钢性能最优，使用寿命最长。安徽凤形生产的中碳低合金衬板性价比高，在耐磨性、韧性等性能在使用过程中非常突出。
Comparing several kinds of wear-resistant materials, the alloy steel has the best performance and longest service life in double medium quenching process. The medium carbon low alloy liner produced by Anhui Phoenix shape has a high cost performance ratio, and its wear resistance, toughness and other properties are outstanding in the use process.
