针对普通低合金钢颚板寿命短的问题 ,采用控制Mn、Mo含量的方法和空气淬火工艺 ,得到贝氏体钢。经现场试验表明 ,用空淬贝氏体钢浇注的颚板 ,其寿命是普通低合金钢颚板的两倍。
Aiming at the problem of short life of common low-alloy steel jaws, a method of controlling Mn and Mo content and an air quenching process are adopted to obtain bainitic steel. The field tests show that the jaws cast with empty-quenched bainitic steel have twice as long life as ordinary low-alloy steel jaws.
