在充分发挥碳在高锰钢中的固溶强化、奥氏体稳定化作用的基础上,以成本为主要控制因素开发的高碳高锰钢获得了成功。将含碳量提高到1.5%的高碳奥氏体锰钢,在经过1060～1100℃加热并适时保温后经水韧处理,得到奥氏体加微量点状碳化物的室温组织,力学性能满足了使用要求,实现了理想的性价比。高碳高锰钢衬板在直径φ1.83 m 的铁矿球磨机上使用,寿命达到1年,比常规高锰钢寿命提高了1倍。
On the basis of giving full play to the solid solution strengthening of carbon in high manganese steel and the stabilization of austenite, the success of high carbon and high manganese steel, which was developed with cost as the main controlling factor, was successfully achieved. High-carbon austenitic manganese steel with carbon content increased to 1.5% is heated at 1060 ~ 1100 ℃ and then heat treated in time to obtain toughened austenite plus micro-point carbides at room temperature. The mechanical properties meet the requirements The use of requirements, to achieve the ideal price. High carbon high manganese steel liner in diameter φ1.83 m iron ore ball mill use, life expectancy reached 1 year, higher than conventional high manganese steel life increased by 1 times.
