| titleOfInvention | Cooling device, cooling method, manufacturing device, and manufacturing method for hot-rolled steel sheet |
| abstract | Provided are a cooling device, a cooling method, a manufacturing device, and a manufacturing method for a hot-rolled steel sheet, which are capable of manufacturing a hot-rolled steel sheet having ultra-fine crystal grains. The cooling device for a hot-rolled steel sheet is configured so that when the steel sheet conveyance direction length of the interval from the press-down point in the final stand to the exit side of a housing post is denoted by L1, the steel sheet conveyance direction length of a portion in the interval, where high-pressure jet water is continuously ejected toward a steel sheet, is denoted by L2, and the ratio L2/L1 is denoted by X, a steel sheet conveyance direction average value (Ps [kPa]) of the steel sheet surface collision pressure of the high-pressure jet water in the portion having the length L2 satisfies the relationship Ps > 2.5X(-1/0.6); at the upper and lower surfaces of the steel sheet. The cooling method uses the cooling device. The manufacturing device for a hot-rolled steel sheet includes the final stand in a hot finish rolling machine line and the cooling device in this order in the steel sheet conveyance direction. The manufacturing method for a hot-rolled steel sheet includes a step of processing, using the manufacturing device, a steel sheet rolled at the final stand in the hot finish rolling machine line. |
