摘要

PROBLEM TO BE SOLVED: To provide an apparatus for heating a steel strip which prevents temperature rise near a burner and allows a heating range of the steel strip to be controlled.SOLUTION: The apparatus 1 for heating the steel strip includes: a burner 3 which is extended in the width direction of the steel strip 2 and heats the steel strip 2; a pair of air nozzles 5 which are arranged parallel with each other before and behind the burner 3 and each jet air toward the steel strip 2 to form an air curtain; and a base member 4 which is extended from the burner 3 to the air nozzles 5. The front and rear of a gap between the steel strip 2 and the base member 4 are sealed with the air curtain formed by the air nozzles 5, and combustion gas of the burner 3 is guided to the width direction of the steel strip 2.
