改进热处理工艺对节电的潜力很大。在可能范围之内尽量缩短工件在热处理加热时的高温保持时间具有显著的节电效果,也是热处理节能的措施之一。许多文献指出,一般工件热处理加热保持时间的计算过于保守,从许多钢种的高温奥氏体化速度考虑,有可能大大减少淬火和正火加热的计算系数。但是,结合到具体工件,在保证基本质量的前提下,加热保持时间究竟能缩短到何种程度,尚缺乏数量的概念和实践经验。我们结合各种需正火和淬火处理的汽车零件,进行了一系列旨在缩短加
There is great potential for saving energy by improving the heat treatment process. As far as possible within the scope of possible to shorten the workpiece in the heat treatment of high temperature heating time has significant energy-saving effect, but also one of the measures for energy-saving heat treatment. Many sources point out that the calculation of the heat retention time for a typical workpiece heat treatment is too conservative. Considering the high temperature austenitization speed of many steels, it is possible to greatly reduce the calculation coefficients of quenching and normalizing heating. However, the combination of specific workpieces, to ensure the basic quality of the premise, the heating and holding time can be shortened to what extent, the lack of a number of concepts and practical experience. We combine a variety of normalizing and quenching the car parts, a series of shortening plus
