高碳中锰钢是新型的球磨机衬板用钢,实际使用表明,衬板寿命可提高50%以上(较高锰钢)。该钢之所以有优良的抗冲击磨损性能,主要在于:在浇注凝固过程中,经过碳化物孕育处理,消除了在热处理过程中难以消除的粗大网状、片状碳化物,使之在铸造过程中呈孤立块状析出。本文旨在以高碳中锰钢为基础,从孕育方面入手,研究钛、钒等孕育剂对铸态碳化物生长的作用及效果;研究影响孕育的条件及因素。一、试验条件及方法
High carbon medium manganese steel is a new ball mill liner steel, the actual use shows that liner life can be increased by more than 50% (higher manganese steel). The reason why the steel has excellent impact and wear resistance, mainly lies in: pouring solidification process, after carbide inoculation process, eliminating the heat treatment is difficult to eliminate the coarse mesh, flake carbides, making it in the casting process Isolated lumps in precipitation. The purpose of this paper is to study the effects and effects of inoculants such as titanium and vanadium on the growth of as-cast carbides based on high-carbon medium-manganese steel from the aspects of inoculation; to study the conditions and factors that affect the inoculation. First, the test conditions and methods
