Abstract

PURPOSE:To improve the cooling capacity for hot rolling material, by positioning a mutually interfering position of cooling water between the falling and colloiding positions where the water falls on the material from cooling water headers arranged on the upstream and downstream sides, respectively and flows while colliding with each other. CONSTITUTION:In cooling a hot rolling materials, the relation between Qa and Qb is made to be Qb>Qa, where Qa is the flow rate of cooling wate falling in a curtain form from a cooling water header 3a, and Qb is the flow rate of cooling water from a cooling water header 3b on the downstream side. Then the cooling water from the header 3b flows separately to the upstream and downstream sides of the rolling material S, and causes an interfering current 5 between the falling position on the material S from both headers 3a, 3b and the mutually colloiding position on the same, because the flowing rate flowing toward the upstream side is larger than that flowing from the same side by DELTAQ/ 2(DELTAQ=Qb-Qa). Accordingly, the cooling capacity is improved without causing any bad influence by the interfering flow 5 onto the positions of falling and colloiding of the cooling water from the header 3b at the downstream side.
