Temperature Simulation of Slab Cooling Process in Slow-Cooling Pit

摘要: 以缓冷坑能量平衡方程和钢坯、坑体的热传导方程为基础，建立了钢坯在缓冷坑中冷却过程的数学模型，实现了缓冷坑冷却全过程的数学描述。模型的辐射热交换部分采用了全交换面积的概念，有效减少了重复计算，在此基础上实现了缓冷坑冷却过程及其温度的离线模拟。

Abstract:  Based on energy balance equation of slow-cooling pit and heat transfer equations of steel slab and the pit, a mathematical model of slab cooling process in slow-cooling pit was established to give a mathematical description of the whole slow-cooling process. The concept of total radiant exchange area was employed is the radiant heat transfer section of the model, which avoids the repeated computation. The offline simulation of the cooling process and tem- perature distribution were realized in this paper.
