ABSTRACT:
A continuous preheat charging method including the steps of transferring scrap from a receiving point to a discharge point, preheating scrap adjacent the discharge point prior to delivery of preheated scrap to one of a pair of melting furnaces, and alternately feeding preheated scrap to the pair of melting furnaces. A continuous preheat charging system is also disclosed which includes a scrap charge transfer conveyor having a scrap receiving end and a scrap discharge end together with a weigh feeder station at the scrap receiving end and a preheating station at the scrap discharge end. After scrap is weighed at the weigh feeder station and fed to the transfer conveyor, the scrap is preheated at the preheating station and delivered to a furnace feeder station to be fed on an alternating basis to one of a pair of melting furnaces.
