| Abstract: | A new mathematical model was established to forecast the steel temperature during the LF refining process on the basis of heat equilibrium of system.The heat transfer in ladlerefractories(including side and bottom) was described with non steady differential equations under one dimension cylindrical coordinates and rectangular coordinates.A computer software using Visual Basic 5 0 language was developed to emulate the real process. The tested result indicates that the deviation of the steel temperature predicted by this model is in no more than five degrees centigrade(between plus and minus) with respect to the real measured data. |
