一、引言耐磨钢种类繁多,大体上可分为高锰钢,中、低合金耐磨钢,铬钼硅锰钢,耐气蚀钢,耐磨蚀钢以及特殊耐磨钢等。作为耐磨钢的重要一个类别,低合金高强耐磨钢由于其合金含量较低、综合性能较好、生产方便灵活、价格便宜等特点,是一种很有发展前途的耐磨材料。低合金耐磨钢具有很高耐磨性能和较好冲击性能,能够进行切割、弯曲、焊接等,可采取焊接、塞焊、螺栓连接等方式与其他结构进行连接,在维修现场过程
I. Introduction A wide range of wear-resistant steel, in general, can be divided into high manganese steel, medium and low alloy wear-resistant steel, molybdenum silicon manganese steel, corrosion-resistant steel, abrasion-resistant steel and special wear-resistant steel. As an important category of wear-resistant steel, low-alloy high-strength wear-resistant steel is a very promising wear-resistant material due to its low alloy content, good overall performance, convenient and flexible production and low price. Low-alloy wear-resistant steel with high wear resistance and good impact performance, capable of cutting, bending, welding, etc., can take welding, plug welding, bolting and other means to connect with other structures in the maintenance process at the scene
