摘要

针对高锰钢犁铧耐磨性较差，为了提高犁铧的韧性及耐磨性，降低犁铧的断裂与磨损，在改变碳元素的基础上研究淬火方式对耐磨钢的组织与性能的影响。结果表明：随着碳含量升高，局部水淬/空淬钢的硬度逐渐升高，而冲击韧性逐渐降低。碳含量为0.344%，热处理工艺为“940℃淬火×1.5h＋局部水冷/空冷＋200℃×3h回火”试验钢的综合力性能最好，水淬部分硬度为49HRC，冲击韧性ak值为145J/cm2；空淬部分硬度为30HRC，冲击韧性ak值为260J/cm2。经过装机应用试验，局部水淬/空淬钢材质犁铧的使用寿命是高锰钢材质犁铧的2~3倍。

Abstract

In view of the poor wear resistance of high manganese steelploughshare

in order to improve the toughness and wear resistance ofploughshare and reduce the fracture and wear of ploughshare

the influence ofquenching method on the microstructure and properties of wearresistant steelwas studied on the basis of changing carbon elements.The results show that withthe increase of carbon content

the hardness of local water quenching/airquenching steel increases gradually

and the impact toughness decreasesgradually. The carbon content is 0.344%

and the heat treatment process is “940℃quenching×1.5h+local water cooling/air cooling+200℃×3h tempering”.The test steel hasthe best comprehensive performance. The hardness of the water quenching part is49HRC

and the impact toughness ak value is 145J/cm2; the hardness of the airquenching part is 30HRC

and the impact toughness ak value is 260J/cm2. ?Afterthe installation application test

the service life of the local waterquenching/air quenching steel material plough is 2~3 times as long as that ofthe high manganese steel material ploughshare.
