Flow control method and device for laminar flow cooling

摘要

The present invention relates to a laminar flow cooling system used for water cooling a high temperature steel sheet, wherein the nozzle (11) of the header (10) accommodating the cooling water supplied from the reservoir is provided with an inclined surface and the inclined surface thereof forms a horizontal surface. A, the inclined plate of the row cap stopper 15 to move up and down on the row 11 to open and close the row 11 is formed smaller than the angle formed by the vertical line, and sprayed through the row 11 to the steel sheet Provided are a flow rate control method and apparatus for laminar flow cooling to easily control the flow rate of the cooling water.
