HEATING APPARATUS FOR TWIN-BELT CASTING MACHINE

摘要

HEATING APPARATUS FOR TWIN-BELT CASTING MACHINE Heating apparatus for use in a twin-belt casting machine in which a casting region is defined between opposed portions of the front faces of a pair of revolving endless flexible casting belts and in which the molten metal to be cast is introduced into the casting region to be carried along between the front faces of the belts as it is being solidified. The apparatus comprises a plurality of banks of radiant heaters, first support means mounting one of the banks of heaters closely adjacent to the front face of one of the casting belts in a position located before the revolving belt enters the casting region, and second support means mounting another of the banks of heaters closely adjacent to the front face of the other casting belt in a position located before the revolving belt enters the casting region, and the first and second support means aiming the banks of heaters to direct intensive radiant energy onto the front faces of the respective belts at close range for pre-heating the belts before they enter the casting region, thereby to minimize the distortion of the casting belts after they begin carrying the molten metal between them in the casting region.
