Abstract
Studies into multiple heating and relating to energy conversion, electrical efficiency and temperature distribution have shown that a single inductor is amenable to heating several workpieces at the same time and that this method is appropriate. Theoretical and experimental investigations show that in multiple heating it is necessary for a generator to be used whose operating frequency has to be adapted to the dimensions of the workpiece in order to comply with the condition that the ratio between workpiece thickness and electromagnetic penetration d/ delta greater than 3 for all workpieces to be heated at the same time. Electrical efficiency depends on the number of workpieces and the volumetric efficiency of the inductor cross-sectional area. In multiple heating only those workpiece arrangements should be employed in which the individual workpieces exhibit almost equal heat losses. This requirement can be met by exclusively admitting workpieces which are subject to a direct exchange of radiant energy with the refractory lining. Furthermore, heat losses and temperature differences can be reduced by using a lining providing better thermal insulation or by arranging an artificial radiation shield between the workpieces and the lining.
