对连铸板坯辊道输送和堆冷过程的变形问题进行了有限元热力分析。分析结果表明,冷却初期辊道输送和堆冷过程铸坯都会发生两端翘曲变形,冷却后期辊道输送过程铸坯会恢复平直而堆冷过程铸坯会发生反向弯曲。堆冷过程中加盖保温罩能使铸坯在冷却后期恢复平直而不发生反向弯曲,并且铸坯内残余应力也变小了。
The finite element thermal analysis of the deformation of continuous casting slab roller conveyor and stack cooling process was carried out. The analysis results show that both ends of the slab will be warped and deformed in the process of roller conveyor and stack cooling in the early stage of cooling, and the slab will be reclaimed in the late stage of roller cooling and the slab will be bent backwards in the process of pile cooling. Stamped in the cold during the insulation cover can make the billet in the late cooling recovery without reverse bending, and the slab residual stress is also smaller.
