Abstract

PURPOSE: To save energy by communicating the terminal end part of a preheating zone and the beginning end part of a cooling zone as well as the terminal end part of the cooling zone and the beginning end part of the preheating zone by means of ducts, and circulating the gaseous atmospheres of the cooling zone and the preheating zone with convection fans.
CONSTITUTION: In a continuous heat treatment furnace installing in series a preheating zone 6 and a cooling zone 7 by means of intermediate fans 2a, 3a to both sides of a high temp. treating zone 2, the terminal end part 6a of the zone 6 and the beginning end part 7b of the zone 7, as well as the terminal end part 7a of the zone 7 and the beginning end part 6b of the zone 6 are communicated respectively by means of ducts 13, 14. Convection fans 15, 16 are provided to the ceiling parts of the zone 6 and the zone 7, and the gaseous atmospheres of the zone 7 and the zone 6 are circulated to the part 7b→ the part 6a→ the part 6b→ the part 7a.
