采选设备零件磨损伊,是克里沃罗格矿区的严重问题。破碎车间的设备零部件和露天矿挖掘机铲齿,在使用过程中都受到剧烈的磨蚀性磨损和较大的动载荷。根据矿业生产条件,已广泛采用110Г13Л号锰钢,这种钢在同时受磨损和冲击负荷作用下,具有很大的极限抗拉和抗冲击强度,以及良好的抗磨损性能。它的主要缺点是初始硬度较低,其布氏硬度不超过180～220。在磨蚀性磨损
The wear and tear on mining equipment parts is a serious problem for the Krivoy Rug Mine. Equipment parts and crushing plant excavator shovel teeth in the open pit, during use are subject to severe abrasive wear and greater dynamic load. According to the conditions of mining production, 110Г13Л manganese steel has been widely used. This steel has great ultimate tensile and impact strength and good wear resistance under both simultaneous wear and impact loads. Its main drawback is the lower initial hardness, its Brinell hardness does not exceed 180 ~ 220. In abrasive wear
