Abstract
PURPOSE:To uniformly cool the part near the joint part of a steel strip in the transverse direction thereof by tracking the joint part of the steel strip and previously outputting gas jet coolers for control corresponding to a change in the width of the steel strip. CONSTITUTION:The current passed strip 1 and the strip 2 to be passed next are connected at a weld point 3 and are cooled by cooling rolls 5a-5e. Pulses are outputted from a pulse generator 10 to a preset counter 11 at every specified length of the strips at this time and the timing when the weld zone 3 arrives at the point before the specified length from the inlet of a cooling zone is determined as set calculating timing 101. A preset controller 15 is started at this timing. The width 102 of the strip to be passed next is further outputted from a width setter 12 to the preset controller 15. The preset controller determines a gas jet cooler pattern 104 for the strip to be passed next and preset start timing from the actual value 105 of the gas jet coolers 7 and controls the gas jet coolers 7 in such a manner that the transverse temp. distribution near the weld zone is uniformized.
