在省机械局领导下,由厂、所、校组成的中小型电机铸造攻关试验组,赴本省有关电机厂对电机铸件质量进行了调查学习。现将一些厂解决铸件质量问题的经验综述如下: 一、解决铸件材质硬的方面电机铸件材质硬是比较普遍存在的问题,不仅加工困难,而且容易产生废品。其原因: 1.原料用含碳、硅较低,含硫磷较高的土铁、土焦,在熔炼过程中又未采取增碳、硅及脱硫磷的措施,所以容易出现白口。
Under the leadership of the Provincial Bureau of Machinery, the small and medium-sized motor foundry research team consisting of factories, institutes and schools conducted investigations and studies on the quality of motor castings in the relevant motor factories in the province. Now some plants to solve the problem of casting quality of the experience summarized as follows: First, to solve the hard aspects of the casting material Motor castings are hard material is more common problems, not only processing difficulties, but also prone to waste. The reasons: 1. Raw materials with carbon, silicon is lower, high sulfur phosphorus soil iron, soil coke, in the melting process did not take carbon, silicon and phosphorus removal measures, it is prone to white.
