ABSTRACT:
A process and a device for reheating gobs of glass by means of a reheating drum are characterized by the fact that the heat-insulating lining of the reheating drum has a low heat-penetration factor, and an energy-rich combustion-gas mixture is used. In this way, the inner surface of the lining is heated to a temperature of at least roughly 1500.degree. C. The short-wave radiant heat on the surface of the lining shortens the heating cycle and thus allows discontinuous operation with corresponding energy savings.
