以WJ-4挖掘机配件高锰钢斗齿的实例,反映高锰钢加钒和稀土试验的结果。由于高锰钢中加钒和稀土使其金相组织得到改善,机械性能明显提高。相同条件下,加钒和稀土高锰钢斗齿的耐磨性比普通高锰钢提高38％。由于使用寿命的延长,铸件的消耗相应减少,在扣除钒铁、稀土所增加的成本后,每用一吨加钒和稀土高锰钢斗齿可节省694元左右,这足以说明高锰钢采用微合金化处理后的经济价值和实际意义。
WJ-4 excavator parts high manganese steel teeth example, reflecting the high-manganese steel plus vanadium and rare earth test results. As the high manganese steel with vanadium and rare earth to improve the microstructure, mechanical properties improved significantly. Under the same conditions, the wear resistance of vanadium and rare earth high manganese steel teeth is increased by 38% than ordinary high manganese steel. Due to the extension of service life, the consumption of castings is correspondingly reduced. After deducting the added cost of ferrovanadium and rare earths, the consumption of vanadium and rare earth high manganese steels can save about 694 yuan per ton, which is enough to show that high manganese steel is used Economic Value and Practical Significance of Microalloying Treatment.
