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.
