A metal strip is continuously cast between a pair of heat conductive endless belts which serve to form a molding zone to solidify molten metal. The endless belts remove heat from the molten metal and are cooled when the belts are not in contact with the molten metal, which minimizes belt distortion.

[ What is claimed is:] [1.] Apparatus for strip casting of metals by continuous belt casting comprising:(a) a pair of continuous, endless belts formed of a heat conductive material, said belts positioned adjacent each other to define a molding zone there between and each belt being carried on a plurality of pulleys, said belts each being adapted to be continuously advanced over said pulleys and each defining a cooling zone separate from the molding zone;(b) means for supplying to the molding zone formed between the belts a molten metal whereby the molten metal is solidified between the belts in the molding zone to form a strip of cast metal and thereby transferring heat from the molten metal and the cast metal to the belts increasing their temperature; and,(c) cooling means positioned adjacent to the belts for cooling the belts when the belts are not in contact with either the molten metal or the cast metal, said cooling means serving to reduce the temperature of the belts by removing, when the belts are not in contact with either the metal or the cast strip, substantially all of the heat transferred by the molten metal and the cast metal to the belts. [12.] A method for the casting of metals by continuous belt casting comprising the steps of moving a pair of endless belts positioned adjacent to each other and defining a molding zone there between, depositing in the molding zone between the belts a molten metal whereby the molten metal solidifies in the molding zone to form a strip of cast metal while transferring heat from each of the belts to increase their temperature and cooling each of the belts to remove the heat transferred to them from the molten metal and cast metal when the belts are not in contact with the molten metal and before the belts receives additional molten metal. A method as defined in claim 12 wherein each of the belts is substantially free from any thermal barrier coating on the surfaces thereof. A method for the casting of metals by continuous belt casting comprising the steps of moving a pair of endless substantially horizontal belts formed of a heat conductive material over a pulley to form a molding zone between the belts, depositing in the molding zone a molten metal whereby the molten metal solidifies in the molding zone to form a strip of cast metal while transferring heat to the belts and cooling the belts to remove the heat transferred to the belts from the molten metal and the cast metal when the belts are not in contact with the molten metal or the cast metal and before the belts receives additional molten metal. A method as defined in claim 14 wherein the molten metal is supplied in a substantially horizontal stream to the molding zone. A method as defined in claim 14 wherein said metal is an aluminum alloy. A method as defined in claim 14 which includes the step of conveying the strip of cast metal from the molding zone between the surfaces of the belts. A method for the casting of metals by continuous belt casting comprising the steps of moving a pair of endless belts positioned adjacent to each other and defining a molding zone there between, depositing in the molding zone between the belts a molten metal which solidifies to form a strip of cast metal and cooling each of the belts to remove the heat transferred to them from the molten metal and cast metal when the belt is not in contact with the molten metal and before the belt receives additional molten metal. A method for the casting of metals by continuous belt casting comprising the steps of moving a pair of endless substantially horizontal belts formed of a heat conductive material over a pulley to form a molding zone between the belts, depositing in the molding zone a molten metal which solidifies in the molding zone to form a strip of cast metal and cooling the belt to remove the heat transferred to the belt from the molten metal and the cast metal when the belt is not in contact with the molten metal or the cast metal and before the belt receives additional molten metal.
