ABSTRACT:
A device is provided for melting by direct induction substances which are dielectric when cold and whose temperatures of inductibility and melting are close to each other, such as glasses or vitreous enamels. This melting is carried out inside a receptacle whose sidewall comprises a multi-turn inductor made from metal tubing whose inward-looking faces are exposed and which combines the functions of heating the charge by induction and cooling the periphery thereof. Such a receptacle which is at the same time a heating inductor and a cooling surface is applicable more especially to industrial electric furnaces for the production of molten glass or enamel by direct induction.
