ABSTRACT:
Several ladles 11-14 for receiving hot metals are preheated by applying a lid 40, 42 to the rim of each ladle and directing an open flame through the lid into the ladle. The hot exhaust gases move back through the lid and through a heat exchanger 35-38 to heat the oncoming combustion air, and the exhaust gases from the ladles being preheated are combined and directed through a lid 41 applied to a ladle at a drying station to dry the ladle.
