Abstract (en)

[origin: EP1634657A1] The present invention relates to a control cooling system (accelerated control cooling system) for a steel plate after completion of hot rolling and a cooling apparatus. To be specific, the present invention relates to a control cooling system for a steel plate after completion of hot rolling, including uniformizing the temperature distribution in the width direction of the steel plate before control cooling or in the initial stage of control cooling, and then cooling the steel plate at the same cooling rate across the width direction with a control cooling device, a steel plate produced by the control cooling system, and the cooling apparatus.
