摘　　要：研究了５９０ＭＰａ级工程机械用高强度厚钢板调质工艺参数。分析在不同淬火、回火温度条件下钢板的组织与力学性能的关系。该钢在９２０℃淬火、５８０℃回火获得细的回火索氏体，其综合力学性能均超过标准要求。The effect of the quenching tempering technological parameter on microstruc ture and mechanical properties of 590 MPa high strength thick steel plate which is used for engineering machinery has been studied According to the analysis of relationship of microstructure and properties of plate in the different quenching and tempering temperature conditions,it is found that the fine tempering sorbite and the strength and ductility,which are in accord with the standard requirement,of the steel plate have been obtained in condition of 920 ℃ quenching temperature and 580 ℃ tempering temperature
