摘要
为准确控制板坯热送入炉温度，利用ANSYS有限元软件，对板坯堆垛温度场及温降速率进行了数值模拟计算。通过控制堆垛时间，使板坯人炉温度稳定在500—550℃，从而消除热送板坯轧后钢板表面爪裂的缺陷。模型计算结果表明，250，320mm厚板坯分别堆垛12，24h后，堆垛中心板坯表面温度达到600℃以下，可满足热送要求。
The ANSYS FEM software has been made use of to carry out the numerical simulation of stacking temperature-field and temperature-drop rate in order to control the charging temperature of hot charging slabexactly. The charging temperature has been controlled between 500 ℃ and 550℃ by controlling the stacking time, and the claw-cracks on the plate have been avoided after hot charging. The result of model calculation has shown that the surface temperature of slabs in the stacking center was below 600℃ after slabs with the thickness of 250 mm and 320 mm have been stacked about 12 and 24 hours respectively, which can meet the requirement of hot charging.
