摘要
采用多元素合金化的中碳低合金钢铸造风扇磨煤机冲击板,通过等温淬火处理,得到贝氏体与马氏体组织,硬度HRC≥45,冲击韧性a_k≥40J/cm^2。装机运行表明,具有较高的抗磨性能。
The impact plate used in fan-type crashing machine is made of multi-alloyed medium carbon low-alloying steel inc which bainite and martenite are obtained throuth isothermal quenching. Its properties are HRC 45 and ak 40J/cm. The experimental.result shows that its wear resistance is pretty good.
