    摘要: A cooling system that cools hot rolled long steel bar, provided with a plurality of chambers that are arranged along the longitudinal direction of the rolled steel bar. Each of the plurality of chambers is provided with a blow outlet that, facing from the chamber to the rolled steel bar, blows out compressed air for cooling that is introduced to the chamber from a gas inlet that is connected to the chamber; a nozzle plate having a plurality of nozzle holes that is provided at this blow outlet so as to face the rolled steel bar; a cooling water supply nozzle that supplies cooling water into the chamber; and a rectifying plate that is provided between the gas inlet and the cooling water supply nozzle, and that prevents the compressed gas for cooling that is introduced from the gas inlet from directly striking the nozzle plate. The cooling system of the present invention sprays a cooling medium that is produced by mixing the cooling water that is supplied from the cooling water supply nozzle and the compressed gas for cooling that is introduced from the gas inlet and rectified by the rectifying plate toward the rolled steel bar through the nozzle holes of the nozzle plate, and performs uniform cooling of the surfaces of the rolled steel bar.

    摘要: A device for cooling a rail weld zone according to the invention includes a first cooler cooling a head portion of the rail weld zone, a second cooler cooling a rail web portion of the rail weld zone, and a control section controlling the first and second coolers. The first cooler includes a first temperature detecting section that detects the temperature of the head portion, and a first ejection section that ejects a first cooling fluid to the head portion. The second cooler includes a second temperature detecting section that detects the temperature of the rail web portion, and a second ejection section that ejects a second cooling fluid to the rail web portion. The control section individually changes the kinds, the flow rates, and the flow velocities of the first and second cooling fluids while cooling the head portion and the rail web portion.

    摘要: In a method of continuously annealing steel strip comprising a heating step (A), a soaking step (B), a primary cooling step (C) including a rapid cooling step at least in a second half thereof, an overaging step (D), and a final cooling step (E), inert atmosphere gas containing H2 gas in the concentration of 30 - 60 % is employed as cooling gas for use in the rapid cooling step, the blowoff temperature of the cooling gas is 30 - 150 °C, and the blowoff speed of the cooling gas is 100 - 150 m/sec. The primary cooling method in continuously annealing steel strip provides the primary cooling step (C) including the rapid cooling step which can be carried out with a high efficiency and a low cost.
