| 摘要 | 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 |
