我厂生产的04型风铲中有几个渗碳件如:阀、阀柜、阀柜垫圈、钢套,在工作中受冲击,磨损,有的耐磨性不高,有的易破碎,寿命不高,后来在不改变材料的基础只改进了热处理工艺,采用高温强烈淬火获得低碳马氏体代替了原渗碳淬火工艺,简化了工艺,提高了零件使用寿命。目前阀柜垫圈和阀已大批生产,现将情况介绍如下。 I plant the production of the 04-type wind shovel in a few carburizing pieces such as: valves, valve cabinets, gaskets, gaskets, in the work by the impact, wear and tear, and some wear resistance is not high, and some easily broken, Life is not high, and later only do not change the basis of the material only improved heat treatment process, the use of high temperature quenching to obtain low-carbon martensite instead of the original carburizing quenching process, simplifying the process and improve the life of parts. At present, valve gaskets and valves have been mass-produced, the situation is as follows.
