以初期凝固坯壳为研究对象，在结晶器内壁纵向划分沟槽，建立数学模型，计算划分沟槽与不划分沟槽结晶器内铸坯的温度场和应力场，研究沟槽内壁结晶器对铸坯初期凝固过程的影响．结果表明，沟槽内壁结晶器可显著改善铸坯传热，降低坯壳应力并使其均匀分布．
Taking the initial solidification shell as the research object, divide the groove longitudinally on the inner wall of the mold, establish the mathematical model, calculate the temperature field and stress field of the slab in the divided groove and non-divided groove mold, Influence of Initial Solidification Process of Billet. The results show that the groove wall mold can significantly improve the slab heat transfer, reduce the stress and make the blank shell evenly distributed.
