Abstract
Metal melted and poured into molds, mounted on a conveyor, at a first station. Metal cools to rolling temperature during conveyance to second station where hydraulic ram ejects ingots from molds. Ingots are immediately fed to rolling mill. Molds have interior refractory linings. Embedded in linings are electrical resistance heating elements that heat exterior side surfaces of ingots, between first and second stations, to prevent those surfaces from reducing below rolling temperatures while interior temperatures of ingots reduce to levels suitable for rolling.
