Abstract
A steel workpiece reheating apparatus and method for raising the temperature of a thin continuously-cast hot workpiece to a required working temperature without causing harm to the workpiece. The apparatus includes a high intensity heating chamber provided at the charging end of a reheat furnace structure which briefly and intensely heats the workpiece above its melting temperature before it enters the remainder of the reheat furnace. The provision of the high intensity heat chamber at the charging end of the reheat furnace structure permits substantial reduction in the length normally required of the reheat furnace to raise the workpiece to the desired working temperature and thus reduces the time spent by the workpiece in the reheat furnace. The high intensity heating chamber uses in its combustion process combustion air preferably preheated by a heat recovery system associated with the heat derived from the combustion occurring within other portions of the reheat furnace. Upon combustion of the preheated combustion air with an appropriate fuel, temperatures above the melting temperature of the steel are achieved within the high intensity heating chamber. The operation of the var…
