铁石英岩矿的磨碎是一道困难、耗能多和代价高的生产工序。因此,在有磨料磨损冲击负荷及腐蚀性介质的条件下工作的磨矿机,提高衬板的寿命是制造业最重要的问题。根据它的工况条件合理选择高锰钢成分,也是改善衬板质量的途径。按ΓОCT2176—77规定普通高锰钢110Γ13Л的化学成份;C0.9～1.4％、Mn11.5～15％、Si0.3～1.0％、Cr<1.0％、Ni<1.0％,S<0.05％、P<0.12％。大量试验表明,把锰含量降低到9～10％,实际上可以消除铸件的热裂废品,提高铸件寿
The grinding of iron quartzite is a difficult, energy-intensive and expensive production process. Therefore, in the abrasive wear impact load and corrosive media working conditions of the mill, to improve the life of the liner is the most important manufacturing problems. According to its working conditions and reasonable selection of high manganese steel composition, but also to improve the quality of liner approach. According to ΓОCT2176-77 provisions of the ordinary high manganese steel 110Γ13Л chemical composition; C0.9 ~ 1.4%, Mn11.5 ~ 15%, Si0.3 ~ 1.0%, Cr <1.0%, Ni <1.0%, S <0.05% P <0.12%. A large number of tests show that the reduction of manganese content to 9 to 10%, in fact, can eliminate the hot cracking waste castings and improve the casting life
