。 When controlling and cooling thick steel plates after hot rolling, this is a masking plate for uniform cooling of the thick steel plates that is installed on the edge of the steel plate in the width direction in the cooling device, and corresponds to the cooling water spout hole of the upper nozzle header of the control cooling device. In addition, the number of through holes is reduced from the center in the width direction of the steel sheet to the ends, and the size of the through holes is approximately equal to the outer diameter of the laminar flow of cooling water jetted from the jet holes. A masking plate for uniform cooling of thick steel plates, characterized by being formed into equal sizes.
