Abstract
PURPOSE: To uniformly cooling entire surface of the steel sheet, and to manufacture the steel sheet of excellent strength and toughness, by applying the controlled cooling to the material steel sheet in the longitudinal direction, at the rolling method with the controlled rolling for repressing the temperature of the final pass to somewhat low temperature.
CONSTITUTION: At rolling the steel material 10 with the rolling mill 12, the steel sheet 10, being carried by the table roller 18, is cooled uniformly all over the pass with the jet stream of cooling water jetted from the water jet nozzles 15, 17, of coolers 14, 16. The final finishing temperature is controlled to somewhat low specified temperature, on purpose to refine the structure of the steel sheet containing Nb, V, etc., and to greatly improve the strength and toughness. Hereupon, the longitudinal temperature distribution of the steel sheet 10 is uniformized by controlling the water cooling of the steel sheet by changing the flow rate of water along the longitudinal direction of the steel sheet 10. Hereby, the entire steel sheet 10 including both edges is finished at uniform temperature, and its strength and toughness are uniformly, greatly improved.
