摘　　要：采用MSC.Marc有限元模拟软件对加热钢坯进行埋偶试验,得出加热炉内部的实际炉气温度,并以此为边界条件。以钢坯入加热炉时的温度为初始条件,建立钢坯在加热炉内的三维温度场模型;计算钢坯在步进式加热炉内的温度场变化情况,得出不同热装温度的钢坯在加热炉内的温度变化;优化实际生产中的加热工艺。该研究为提高工厂生产效率,节约能源起到指导作用。MSC.Marc FEM simulation software was used to simulate the slab-reheating process in a pusher-type furnace.With the thermoelectric pair,the actual gas temperature was obtained as boundary conditions.Taking the slab temperature before reheating as initial conditions,a 3D FEM temperature field model was established.The temperature field distribution was calculated by FEM simulation.The temperature changes in the furnace with the different HCR temperatures were shown.The reheating process was optimized for the actual production.This study provided guidance to improve the reheating efficiency and energy saving.
