Document Type and Number:
Japanese Patent JPS6158525
Kind Code:
B2
Abstract:
A continuous heating furnace (30) for flat steel products (20) has a movable wall (40) which can be positioned closer or farther away from the transverse edges of the steel products (20) in order to adjust the heat radiation applied to the opposing edges of the steel products (20). The movable wall (40) extends parallel to the longitudinal axis of a course along which the steel products (20) are transported through the furnace. The movable wall (40) constitutes part of a ceiling (32) of a furnace body (30) and can be shifted vertically toward and away from the transverse edges of the steel products (20) 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 products (20). The movable wall (40) is provided with cooling elements (44) to adjust the heat radiation from the steel products (20).
