Abstract

PURPOSE:To make the cooling effect for a rolling material higher and installations smaller by disposing flat-plate like guides in proximity to the rolling material, and forming water film flow in the clearances between both. CONSTITUTION:An upper header device 10 and a lower header device 30 are disposed above and below the passage for a strip 1. The position in the vertical direction of the supporting beam 13 of the device 10 is adjusted to retain an upper header 19 in a water film flow forming position. In this position, the cooling flow ejecting from a nozzle 20 forms water film flow in the clearance H formed between a flat plate guide 21 and the top surface of a strip 1, thereby cooling the top surface of the strip 1 with high heat conductivity. The cooling water ejecting from the nozzle 32 of the device 30 forms the water film flow in contact with the bottom surface of the strip 1 with the aid of a flat plate-like guide 33, thereby cooling the strip 1. This cooling water flows down onto the outside circumferential surfaces of table rollers 2 and cools the rollers 2.
