708.027 GKP S P E C I F I C A T I O N METHOD AND APPARATUS FOR CONTINUOUSLY CASTING METAL SLAB, STRIP OR BAR WITH PARTIAL THICKNESS INTEGRAL LUGS PROJECT- ING THEREFROM Inventors: Robert William Hazelett John Frederick Barry Wood ABSTRACT OF THE DISCLOSURE Method and apparatus are described for continuous- ly casting metal slab, strip or bar with integral lugs projec- ing therefrom. These lugs project from the edge of the cast product and lie in the casting plane, but they have a partial thickness as compared with the thickness of the product. Continuous wide slabs of unrefined copper or other electro- lytically refinable metal having partial thickness lugs on both edges can be cut to form electrode plates for subsequent refining by suspending in an electrolytic bath. These partial thickness lugs serve as supports and provide elec- trical connection from the side rails of the electrolytic cell. Their partial thickness conserves metal and weight. In the continuous casting method and apparatus the revolving edge dams include special dam blocks defining partial thick- ness mold pockets for casting the integral lugs. Synchroni- zation of lug positions along opposite edges of the cast product is maintained by controllably changing the relative temperatures of the revolving edge dams with respect to each other, for example, by relatively increasing the cooling of one of the revolving edge dams when it tends to lag the other, thereby relatively decreasing its length and increas- ing its rate of revolving, or, for example, by relatively decreasing the cooling of one when it tends to lead the other, thereby relatively increasing its length and decreas- ing its rate of revolving. -1-
