本文较详细地介绍了西德引进的单垛式罩式炉特点。并在此基础上对退火工件(钢卷)均热过程的温度分布情况即钢卷温度变化进行了探讨。通过对若干次退火冷点温度实测数据处理,找出了影响工件热容因素—几何尺寸,重量与冷点升温速率、生产效率的对应数学模型。这是将数学回归分析法用于工业上复杂生产过程中的一次有益尝试。通过生产实践证明该模型实用,简单,并有足够的精度。具有明显的经济效益。 This paper introduces the characteristics of the single-stack hood furnace introduced by West Germany in more detail. On the basis of this, the change of the temperature distribution during the soaking process of the annealed workpiece (coil), that is, the coil temperature, was discussed. Through the processing of measured data of several cold spots, the corresponding mathematical model that affects the factors of heat capacity of the workpiece, such as geometric size, weight, heating rate of cold spots and production efficiency, has been found out. This is a useful attempt to apply mathematical regression to complex industrial processes. The production practice proves that the model is practical, simple and accurate. Has obvious economic benefits.
