摘 要:通过降低高锰钢中的锰碳含量,获得了中锰钢.研究表明:中锰钢经1050~1070℃水淬后的基体组织为奥氏体+0~W2级碳化物,在非强烈冲击工况条件下,满足强韧性要求,而耐磨性能优于高锰钢.应用于制造球磨机衬板,每吨铸件成本可比高锰钢降低约420元,而使用寿命提高16%. 更多还原
Abstract: Medium manganese steel was produced by reducing carbon and manganese content of the high-manganese steel.Research results show that the matrix after water quench at the temperatures of 1050~1070 ℃ is austenite carbide(+0 ~W2 class).The medium manganese steel,whose wear resistance is better than that of the high manganese steel,can meet the requirements of strength and toughness in the non-working strong-impact conditions.The casting cost for medium manganese steel is 420 CNY lower than that of t.
