冶金工矿设备多数处于恶劣的条件下工作,由于受冲击负荷、压力摩擦磨损、高温和化学作用等的影响,因而备件消耗量大。下面主要从材质的选用和铸造工艺等方面探讨提高冶金矿山设备中的耐磨件、钢铁厂的钢锭模和轧钢厂的轧辊等备件的寿命问题。冶金矿山设备中的耐磨件冶金矿山设备的耐磨件种类较多,根据受力状态不同,可分为三类: (1)既受大的冲击负荷,又受大的压力摩擦,如电铲斗齿,破碎机齿板等;
Metallurgical mining equipment, most of the work in harsh conditions, due to the impact load, pressure and friction and wear, high temperature and chemical effects, and thus the consumption of spare parts. The following mainly from the selection of materials and casting technology to explore ways to improve the wear-resistant parts of the metallurgical mining equipment, steel ingot mold and rolling mill mill rolls and other spare parts life issues. Wear parts in metallurgical mining equipment Metallurgical mining equipment wear more types of devices, depending on the state of stress can be divided into three categories: (1) both by a large impact load, but also by the pressure of large friction, such as electricity Bucket teeth, crusher teeth plate;
