| Abstract: | 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. |
