The solidification process in the flow field,the stress field,the temperature field and the microscopic organization shape carry on the value simulation,it can help the technological design personnel to analyze the different time solidification process the temperature distribution,the metal fluid state,the crystal crystal grain size,the stress distribution and so on.The important physical parameter,thus forecasts loose,flaws and so on segregation,mixture and heat crack.Establishes the region cooling system underneath the crystallizer,the controlled area cooling system blows water-wiper the function position,it can prevent the cooling water front ingot casting lower reaches,realizes effect which the region cools.Through the research temperature field,the stress field distribution rule,it analyzes the principle which the ingot casting crack produces,and it can expound macroscopically the ingot casting underbead crack formation reason and seeks the effective regulating control method..
