摘要
综述了铲齿的分类,从铲齿用钢微观组织的不同,分别阐述了各种组织类型铲齿用钢国内外的发展情况,包括其具体化学成分、热处理制度、综合性能以及存在的问题等,归纳了奥氏体耐磨钢铲齿、马氏体耐磨钢铲齿、贝氏体耐磨钢铲齿以及复相组织铲齿的优缺点,总结了现阶段我国铲齿用钢存在的问题,发现贝氏体组织铲齿用钢具有广阔的发展空间。
The classification of the shovel teeth was summarized. From the different microstructures of steels for shovel teeth,the development of steels for various types of shovel teeth had been described at home and abroad,including the specific chemical composition,heat treatment,comprehensive performance and existing problems,etc. The advantages and disadvantages of austenitic wear-resistant steel shovel teeth,martensite wear-resistant steel shovel teeth,bainite wear-resistant steel shovel teeth and composite phase shovel teeth were summarized,and the problems of steels for shovel teeth in China were summarized. It can be found that the steels of the bainite structure has a broad development space.
