COOLING DEVICE, HOT-ROLLED STEEL SHEET MANUFACTURING APPARATUS, AND HOT-ROLLED STEEL SHEET MANUFACTURING METHOD |
摘要 |
Provided is a cooling apparatus discharging water smoothly corresponding to increase of volume density of cooling water securing a high cooling capability. The apparatus disposed on downstream side from a row of hot finish rolling mill, supplying cooling water from above toward a pass line, includes a plurality of cooling nozzles arranged parallel in a pass line direction, and an upper surface guide disposed between the pass line and the cooling nozzles, wherein a predetermined relation is satisfied when defining: a volume density of cooling water sprayed as q m (m 3 /(m 2 · sec)) ; a pitch of the cooling nozzle in the pass line direction as L(m); a distance between a lower surface of the upper surface guide and the pass line as hp(m); a uniform cooling width as W u (m) ; and a cross-sectional area of virtual flow path of discharging water flowing in a width direction of steel sheet as S(m 2 ). |
