1．沈阳重型机器厂、沈阳铸造研究所、本钢南芬第二机修厂共同研制的ZG30CrMnSiMoTi耐磨铸钢衬板于10月7日~9日在沈阳进行鉴定,会议由一机部重型矿山局主持。会议认为该材质衬板经多年试验研究及工业性运转实践证明:①研磨有色金属矿料,其使用寿命较1975年高锰钢提高50%;②研磨黑色金属矿料较高锰钢提高16~26%:故该材质适用于普氏硬度8~12,也可以在14~16的有色、黑色金属矿料的研磨或其他低冲击负荷下代高锰钢制作耐磨零件。③批量生产时减少能源消耗,生产成本较高锰钢降低8%。会议希望不断完善其生产工艺,以扩大应用范围。
1. ZG30CrMnSiMoTi wear-resistant cast steel liner jointly developed by Shenyang Heavy Machinery Plant, Shenyang Foundry Research Institute and Benxi Steel Nanfen Second Machinery Plant was identified in Shenyang from October 7 to September 9, and was chaired by a heavy mining bureau of a machine department . The meeting held that the material lining after years of experimental research and industrial operation proved: ① ground non-ferrous mineral ore, the service life of high manganese steel increased by 50% in 1975; ② Grinding ferrous manganese ore higher manganese steel increased 16 ~ 26%: Therefore, the material is suitable for Platts hardness of 8 to 12, can also be in the 14-16 colored, ferrous metal ore grinding or other low impact load generation of high manganese steel wear-resistant parts. ③ reduce the energy consumption in mass production, reduce the production cost of manganese steel by 8%. The meeting hopes to continuously improve its production technology to expand the scope of application.
