Abstract

PURPOSE:To cool the rolled material uniformly to the aim temperature, by falling the cooling water in the curtain type from the continuous slit installed in the broad direction in the bottom of the water tank placed above the rolled material, when the hot rolled material is to be cooled. CONSTITUTION:The water tank 1 is placed above the strip being delivered from the finishing mill and running in the direction A; the slit nozzle 2 is made in the bottom of the water tank 1 parallelly to the breadth of the strip; the curtain type water current 15 is fallen from the slit nozzle 2 on the strip to cool it. The cooling water header 4 is placed in the water tank 1, and the cooling water is supplied from the water outlet 3; the current of this water is trimmed by the holes 7 of the perforated plate 8 at the side plane of the water accumulator 5; the water flow from the slit 2 is made curtain type by the action of the V-plate of the water accumulator 5. The water supply from the header 4 is put ON-OFF by changing the level of water surface in the water tank, and the water hole 11 of the water falling part 13 is opened and closed by the cover 16 of the breadth adjuster 17 for the falling water 15; hereby, the flow rate of the cooling water is adjusted, and the strip is uniformly cooled.
