Abstract: | The method based on transient heat transfer model is adopted to simulate electro-slag remelting process.The calculated results of the model show that the process is in the quasi-steady state,and the shape of pool remains unchanged when the height of ingot is approximately 2.5-3 times the thickness of slab ingot.The change in the shape of pool is found to be strongly dependent on the pattern of melting rate,and hence,the power input;the depth of the molten pool increases with the increase in melting speed. It is concluded that a transient heat transfer model has to be used to obtain reliable input information for the entire operating time. |
