摘　　要：利用Gleeble-1500热力模拟试验机对试验钢进行了模拟热轧.研究了终轧温度、轧后冷速和Si、Mn含量对试验钢组织的影响.试验结果表明,试验钢在试验工艺参数范围内形成的双相组织有较高的稳定性,具有适应生产中工艺参数波动较大的特点.The experimental steels were hot-rolled by Gleeble-1500 hot-simulated testing machine.Effects of the final rolling temperature,the cooling rate and the contents of Si and Mn on the microstructure are studied.As a result,the experimental steels have good stability of dual-phase microstructure within the the range of experimental hot-rolling parameters and fit for the industrial production conditions which have larger range of processing parameter variation.
