Research on thermal status of 300 t ladle in the process of steel-making and continues casting

The thermal status of the ladle in the process of steel-making-refining-continues casting was tested and the distribution of the lining temperature and the law of the temperature variation in each and every turn-over phase of the ladle studied.The practical results show that the heat was obviously Absorbed and stored in ladle lining in the first and second turn-over phases of the ladle and therefore the thermal compensation should be considered in those periods.However in the third and fourth phases of the ladle,the temperature in every points of the ladle lining changed smoothly.It shows that from the beginning of the 4th phase the change of the ladle lining was held in a recycling process of dynamic equilibrium.
