摘　　要：利用自行研制的大试样平面应变热力模拟试验机,对宝钢DH36船板钢的轧制工艺进行了热模拟与优化,测量了变形过程中材料的流变曲线,并对模拟后的试样进行了显微组织、圆棒拉伸、夏比冲击等分析.结果显示,大试样平面应变模拟技术不仅能满足常规热模拟系统分析的要求,而且模拟后的试样能进行力学性能分析.实验数据表明所模拟的船板钢具有优异的力学性能.Rolling process parameters of DH36 high strength ship plate steel in Baosteel were simulated and optimized with a self- developed and designed large-specimen plane strain thermo-mechanical simulator. The flow stress was measured in the process of deformation. Microstructure observations, round stick tension and Charpy V-notch impact tests of simulated specimens were carried out. The results show that large-specimen plane strain simulation technology not only meets the requirement of microstructure analysis like a general thermo-simulation system, but also the mechanical properties of the specimens can be analyzed after simulation. Experimental data show that the simulated ship plate steel provides with excellent mechanical properties.
