PROBLEM TO BE SOLVED: To provide a cooling apparatus for a hot-rolled steel plate and a dewatering method thereof which can eliminatr the adverse effect affected by residual water on the surface of a steel plate in a cooling zone through which the steel plate is passed without flowing cooling water.SOLUTION: The cooling system includes a plurality of cooling zones which includes water cooling apparatus which are lined up in the conveying direction of the steel plate and also with which the water is respectively blown onto the surfaces of the steel plate. Each water cooling apparatus 4, 5 has water jetting devices as a part of it, in which the jetting direction of the water is inclined in the opposite direction to the conveying direction of the steel plate S and also the water is blown in the whole region in the width direction of the steel plate. In a cooling zone situated next to the cooling zones N1-Nm which are set to perform the water cooling, by blowing the water to the steel plate from the water jetting device which is possessed with the water cooling apparatus in the cooling zone, the residual water is removed. |
