Abstract:The thermal state of ladle in the process of steelmakingrefiningcontinuous casting was tested in Steelmaking Plant of Baosteel. The temperature distribution and its changing rule of ladle lining at each turnover stage were studied. The results show that the heat is obviously absorbed and stored in ladle lining at the first and second turnover stage of ladle, and the temperature loss and thermal compensation should be considered in this period. During the third and fourth turnover period of ladle, the temperature of ladle lining changes gently and locates at dynamical equilibrium since fourth turnover of ladle.
