S P E C I F I C A T I O N IMPROVED BELT BACK-UP APPARATUS AND COOLANT APPLICATION MEANS FOR BELT CASTING MACHINES Inventor: JOHN M. A. DOMPAS ABSTRACT OF THE DISCLOSURE In twin-belt casting machines for continuously casting molten metal improved belt back-up apparatus and coolant application means are provided. The front faces of the casting belts are held firmly against the moving edge dams by wide belt-supporting elements in the form of cylindrical collars on the back-up rollers or longitudinally extending fixed guide members engaging the reverse surfaces of the belts and positioned in alignment with the respective side dams and laterally spaced apart a distance no greater than the lateral spacing of the moving side dams. Nozzles are absent from the coolant supply means in the positions where the belt-support- ing elements are engaging the reverse surfaces of the casting belts. The cylindrical collars may extend inwardly somewhat beyond the inner faces of the side dams and may have peripheral grooves therein for permitting liquid coolant to travel along the reverse surface of the casting belt through said grooves, with narrow fins on the back-up rollers for engaging and sup- porting the reverse surface of the casting belt between said cylindrical collars. The fixed guide members extend between the casting belt and the back-up rollers and are secured by lateral braces extending between the back-up rollers and have saddles therein for receiving journal portions of the rollers fitting in said saddles. -1-
