ABSTRACT:
A steel strip heating furnace has a movable wall which can be positioned closer or farther away from the transverse edges of the steel in order to adjust the heat radiation applied to the opposing edges of the steel. The movable wall extends parallel to the longitudinal axis of a course along which the steel is transported through the furnace. The movable wall constitutes part of a ceiling of a furnace body and can be shifted vertically toward and away from the transverse edges of the steel so as to adjust the high-temperature heat radiation transmission area about the opposing transverse edge and thus control the heat applied to the corresponding section of the steel. Also, it is especially advantageous to provide means for cooling the movable wall so as to adjust the heat radiation therefrom. Therefore, the heating furnace can control the heat applied to the transverse edges of the steel so that the entire surface of the steel can be heated uniformly.
