对KmTBCr26白口铸铁的实验研究和生产应用

Study on KmTB26 White Cast Iron and Its Application

采用热模技术,对不同模数铸件,就KmTB26牌号铸铁中Mn、Mo、Cu等合金元素对铸铁硬度的影响进行了研究,对于中等壁厚铸件,得出了适宜的铸铁化学成分和热处理规范,用研制的合金成分生产矿浆泵用铸件,其使用寿命长。

In some certain modulus of casting the effected elements Mn,Mo,Cu of KmTBCr26 white cast iron on hardness of the cast iron is studied using heat-simulated technology, For middle well thickness castings, the chemical composition and heat treatment technology available to make KmTBCr26 white cast iron are gained. The castings of a mud pump produced with a reseached KmTB26 white cast iron has a long service life.
