摘　　要：针对堆冷过程中铸坯温度的变化规律，采用数学模拟和现场实测方法进行了研究。研究表明：堆冷开始时，堆垛的中间区域是高温区，随着冷却时间延长，高温区缓慢向下移动；冷却速率最快的是顶部铸坯，而中间区域和底部区域的冷却速率较慢，堆冷铸坯的冷却速率为8．1-14．2K·h^-1.The temperature changing regularity of slab are studied during stack cooling process by mathematical simulation and field measurement. The results are as follows：The higher temperature field is in the center of stack at the beginning of stack cooling, and move down as time goes ahead. The cooling rate of slab at stack top is faster than stack center and stack bottom. The cooling rate of slab during stack cooling process is 8.1-14.2 K · h^-1.
