Filed: 1978-10-24
Abstract: PURPOSE:To prevent adverse influence of heat change on upper and lower spray nozzles by letting the upper spray nozzle retreat at the passing of red hot steel plate other than at the hardening and replenishing the amount of water lost in the lower spray nozzle at a suitable time. CONSTITUTION:A red hot steel plate 1 is conveyed along a pass line 2. In the case of normalizing and tempering which do not require water cooling, a main pump 10 is stopped and upper rollers 4, upper spray nozzle 5 and upper heater 6 are raised up to the upper limit. At this time, the water in the lower header 9 and lower spray nozzle 8 flows by gravity and disappears. Thereupon, the water in a water collecting pit 16 is sucked up by a small pump 22 before or after the passage of the steel plate 1. This water is then sucked into the lower spray nozzle 8 to cool the outside surface of the nozzle 8. Then, even if the nozzle 8 receives radiation heat during passing of the red hot steel plate, it will not deform and its slit width a is maintained.
