摘　　要：利用Ｇｌｅｅｂｌｅ－１５００热模拟试验机对试验钢进行了模拟热轧．研究了合金元素硅、锰和终轧温度、轧后冷速和轧制变形对试验钢双相组织形成和性能的影响．结果表明：在试验工艺参数范围内，试验钢均获得双相组织，其稳定性较好．导出了估算热轧空冷Ｓｉ－Ｍｎ双相钢的ｆ_Ｍ和ｆ_（Ｆｐ）值的计算式，计算值和实测值吻合．热轧参数对试验钢硬度的影响较小．The experimental steels were hot-rolled by Gleeble-1500 hot-simulated testing machine, The effects of Si,Mn, final rolling temperature, after-rolled cooling rate and rolling deformation on the formation of dual-phase microstructure and property of experimental steels were studied.As a result, the experimental steels have good stability of formation of dual-phase microstructure within the range of experimental hot-rolling parameters, then the properties are also stable.
