Abstract

A furnace has a force cooled body in which is mounted a crucible. Between the crucible and the body is a space for a heat transfer medium e.g. molten slag. Within the crucible are electrodes extending along the main axis of the crucible floor. These electrodes are formed or bent up metal. It is used for heating metal articles in oxygen-free conditions. The covering of the crucible with the heat transfer medium prevents erosion. The shape of the electrodes induces an electro-magnetic flux which reinforces convection within the crucible.
