On the influence of coil design and electromagnetic configuration on the efficiency of an induction melting furnace

An investigation is done on a novel configuration for an induction melting furnace which is a combination of conventional channel and coreless induction furnaces. The efficiency of the furnace is determined for various coil and magnetic core designs, and these designs are compared with one another. A finite-element simulation of the furnace is done and compared with the results from the experimental furnace in order to evaluate the value of these simulations in the development of furnaces. The method used in determining the efficiency is evaluated and suggestions on the improvement thereof is given.
