摘要
本文研究了20MnVB钢二相区加热温度、回火温度、预淬温度对亚温淬火组织、性能的影响;确锭了最佳亚温淬火工艺。矿用连接环经亚温淬火后性能明显提高,可全面满足C级技术要求。
This paper deals with the influence of the temperature of heating in two-phase state,tempering and prequenching on the structure and properties of suberiticslly quenched 20MnVB steel,and determines the optimal process of subcritical quench. The connective rings for coal-mine will be increased in properties obviously after subcritical quench, and meet the technological regurements of grade C completely.
