Abstract

PURPOSE:To save the energy of a titled furnace by continuously circulating liquid heating medium into respective hollow roll groups of a preheating part and cooling parts and preheating a strip passed through the hollow rolls of the preheating part. CONSTITUTION:In a continuous heating furnace for a metallic strip 6 successively disposed with a preheating part 1, a heating and soaking part 2, a primary cooling part 3 and a secondary cooling part 4 in series, first the high temp. liquid heating medium 8 in a heat medium storage vessel 7 is fed to the hollow roll 5 group of the part 1 by a circulating pump 9, thereby preheating the strip 6 which is being passed through the roll 5 group while being looped. The heat medium 8 having lowered to a low temp. by being heat exchanged is fed to the roll 5 group of the part 3 by a connecting pipe 10, and is heated by the sensible heat of cooling of the strip 6 to have higher temps., thence it is returned into the storage vessel 7. In this way, the energy of the continuous heat treatment furnace is saved by utilizing the sensible heat of cooling of the strip 6 for preheating.
