| 摘 要： | 采用有限元法,建立了热轧步进式加热炉内板坯三维温度场的数值计算模型.通过现场拖偶实验确定了板坯加热的边界条件,并验证了模型计算结果的准确性.计算结果表明,在保证板坯加热质量的前提下,提高加热炉预热段炉温、板坯入炉温度有利于缩短板坯在加热炉内的加热时间,提高加热炉生产效率.

| Abstract: | A mathematical model for numerical simulating the temperature distribution in reheating furnace of hot rolling process is developed by using FEM method.The heat transfer boundary condition of slab is determined by Furnace black box testing,while the validity of the numerical simulation is verified by using the black box testing experimental data.The results indicate that raising the temperatures of preheating section and the slab initial could shorten the slab heating time,guarantee the final quality of slab and improve the reheating furnaces productivity. |
