This invention provides a method and apparatus for casting, hot rolling and annealing of non-heat treatable aluminum alloys which comprises continuously casting, hot rolling, and, in-line with the hot rolling line, inductively heating the aluminum sheet. The induction heating system uses a feedback control to assure that the aluminum alloy is heated to the proper temperature based on one or a number of process variables, such as hot rolling exit temperature, hot rolled product exit rate in terms of speed and product dimensions, and sheet temperature at the exit of the induction heater. Variations in the induction heating temperature can be tolerated in the product without deviating from target mechanical properties.

An apparatus and method for continuously casting molten metal, wherein the apparatus comprises first and second endless belts and first and second edge dam block continuous belts disposed to form a casting region wherein molten metal can be cast into strip. The edge dam blocks have a length longer than the endless belts to form catenaries spaced from the first endless belt. The edge dam blocks are inductively heated with induction heaters disposed in the catenaries to avoid temperature shock to the edge dam blocks during the casting and to minimize undesirable heat losses.
