摘　　要：为了优化Q345D控轧控冷参数,在G leeb le试验机上进行了热模拟试验,确定了热变形工艺参数以及热变形后冷却速度对相变开始温度、相变进行速度和组织的影响,为Q345D在中板二线上的顺利开发奠定了坚实基础。To optimize the controlled - rolling and controlled - cooling parameters of Q345D steel, a hot - simulation test is done with Gleeble testing machine, the hot deformation process parameters are determined, as well as influence of the cooling speed after deformation on the starting temperature and the conducting speed of phase transformation and the structure, and so creates a base for the development of Q345D steel in medium - plate line.
