METHOD FOR ADJUSTING FURNACE ATMOSPHERE IN CONTINUOUS ANNEALING FURNACE

摘要

Conventionally, when the inner furnace of the continuous annealing furnace is to be reduced in the refiner, the problem that the local decrease in the furnace inner temperature can not be prevented without addition of the heat quantity is solved. Gas which is a part of the inner atmosphere is introduced into the refiner 8 provided outside the furnace and is dehumidified and deoxidized. Thereafter, the gas after the dehumidification / deoxidization out of the refiner 8 is introduced into the refiner 8 Exchanged with a gas to be introduced into the furnace interior heat exchanger 11, and then the furnace inner heat exchanger 11 provided in the furnace is heat-exchanged with the furnace atmosphere, and then blown into the furnace again.;
