Abstract

PURPOSE: To make possible the straightener to automatically remove the strain from the steel sheet, by laying the rail parallelly to the strined portion in the steel sheet, and by letting the traveling truck, on which the torch and cooling nozzle are installed facing to the strained portion, to travel on the rail.
CONSTITUTION: The rail 2 is laid on the steel sheet 1 parallelly to the strained portion. Then, the traveling truck 3 is located so as to sit astride of the rail 2 corresponding to the starting point of the strained portion, and the tip of torch 4 and cooling nozzle 6 are arranged at a specified position above the strained portion. After that, the water supply from the unillustrated water supply unit to the cooling nozzle 6 through the cooling water hose 39 is started, besides, the power supply switch 52 is closed and the torch 5 is actauted for starting the heating of steel sheet 1 in the strained portion. A sine wave pattern is made by the torch 5 and cooling nozzle 6 according to the lateral reciprocal motion of the arm 4 and the forward movement of the traveling truck 3, depending on the specified actuator.
