摘要
对空心钢锭凝固过程的温度场进行了有限元分析 ,对不同锭型结构的芯部换热系数、耐火材料厚度对最终凝固位置、内筒壁最高温度及缩孔疏松的影响进行了对比 。
Temperature field of hollow ingot solidification is simulated by FEM.To different mould,effect of heat transfer coefficient between inner sleeve and cooling medium and thickness of core refractory on final position of solidification,the highest temperature of inner sleeve against cooling medium,and shrinkage cavity and porosity are compared.In addition,change of temperature in typical position of core refractory is also compared.
