Abstract (en)
[origin: US6693949B1] The aim of the invention is to provide a means of also cooling the lower part of electric arc furnaces and/or resistance furnaces. To this end, said lower part-the actual melting vessel (4)-is surrounded with a jacket (9) at a certain distance, forming a shell, and the resulting intermediate space is configured as a cooling device (10) and subjected to the action of a cooling medium (14).
