一、热变形模拟试验技术的重要性直接利用生产轧机,对热轧过程进行研究,虽然更加接近实际,但是,从经济上和技术上考虑,这样的研究是昂贵的。同时,常常无法按照试验要求,精确地改变和控制各种参数,以致得到的数据和知识,往往不能应用。在实验室进行热变形模拟试验,是一种价廉而又方便的方法。可以按照预先编制好的程序,对变形温度、应变、应变率、间隔时间等变量,进行精确地控制,以模拟实际热轧过程的轧制温度——速度——压下量——时间等参数,以及轧后冷却条件,从力学冶金和物理冶金方面,对热轧过程进行研究,获得有关钢和合金的成分——冶炼条
First, the importance of thermal deformation simulation test technology The direct use of the production mill, the hot-rolled process, although more realistic, but from the economic and technical considerations, such studies are expensive. At the same time, it is often not possible to precisely alter and control various parameters as required by the test, so that the resulting data and knowledge often can not be applied. In the laboratory for thermal deformation simulation test, is a cheap and convenient method. According to pre-programmed procedures, the deformation temperature, strain, strain rate, interval time and other variables can be accurately controlled to simulate actual hot rolling process parameters such as rolling temperature-speed-reduction-time , As well as cooling conditions after rolling, from the aspects of mechanical metallurgy and physical metallurgy, the hot-rolling process is studied to obtain information on the composition of the steel and the alloy-smelting strip
