| PURPOSE: To improve strength and homogeneity of a steel plate, by controlling cooling conditions so that transformation velocity agree with that necessary to obtain the mechanical properties required of hot-rolled steel plate after cooling. CONSTITUTION: The desired value of the transformation velocity necessary to obtain the mechanical properties finally required of the hot-rolled steel plate is predetermined. Succeedingly, a γ/α transformation ratio of the hot-rolled plate within the cooling-control interval is detected by a transformation ratio detector and the time elapsed from the start of the cooling is measured so as to find the transformation velocity of the plate in the cooling stage. Then the cooling conditions are controlled so that the transformation velocity in the cooling stage agrees with the desired value mentioned above. COPYRIGHT: (C)1986,JPO&Japio | ||||||

In this case, transformation amount detectors 34, 36, 38, 40, 42, 44, 46 each for knowing the gamma/alpha phase ratio of the steel plate 10 by detecting the change in the magnetic characteristics of steel generated with gamma-alpha transformation are provided at appropriate positions. On the other hand, the desired transformation amount at each point of time set from the standpoint of the final material quality of the steel plate 10 is preliminarily inputted to an operation apparatus and compaed to the transformation amount from each of the detectors 34- 46. In order to eliminate the deviation thereof, one or more of the temp. control apparatuses 60, 62, 66, 68 of the heating zone, the holding zone and the cooling zones and a steel plate supply speed control apparatus 70 are controlled. | ||||||
