高碳半马氏体耐磨铸钢是具有高耐磨性的一种新型耐磨铸钢,用于研磨水泥熟料的球磨机衬板,在沈阳市房产局水泥厂运转一年仅磨损5—8毫米,比高锰钢提高使用寿命一倍以上,现已通过机械工业部主持的鉴定。新钢种的化学成份:C1.5—1.7％,Si1.2—1.5％,Mn4—6％,P、S≤0.045％,Cr1.8—2.3％,Ti、V,0.25—0.35％。新钢种基体为奥氏体加马氏体,在基体上镶嵌大量分散的块状碳化物,除具有较高的硬
High-carbon semi-martensitic wear-resistant cast steel is a new type of wear-resistant steel with high wear resistance, used to grind cement clinker mill liner in Shenyang City Real Estate Bureau cement plant operation only wear 5- 8 mm, higher than the high-manganese steel to improve service life more than doubled, has been approved by the Ministry of Machinery Industry identification. The chemical composition of the new steel: C1.5-1.7%, Si1.2-1.5%, Mn4-6%, P, S≤0.045%, Cr1.8-2.3%, Ti, V, 0.25-0.35%. The new steel substrate for the austenitic plus martensite, inlaid in the matrix a large number of scattered bulk carbides, in addition to having a higher hardness
