Abstract
PURPOSE:To prevent a reduction in strip feeding speed due to unsatisfactory form by determining the no. of temp. control members to be operated to required temp. control capacity and setting a predetermined no. of inlet side members out of the operated temp. control members so that the temp. control capacity is raised gradually. CONSTITUTION:Strip 4 passed through soaking zone 1 is introduced into cooling zone 2, where it is passed through strip feeding passes formed with hearth rolls 3 in a zigzag direction, and it is moved out of the furnace. Blast vol. pattern setting unit 15 receives signals from early-stage blast vol. operator 14, feed-forward strip temp. controller 8, feed-back strip temp. controller 10 and strip position tracer 11 to send a control signal to controller 12 for jet coolers 5. For example, considering the total blast vol. required to hold the strip temp. at the outlet of zone 2 at the desired value T0 to be 100%X19=1900%, No.18-21 coolers 5 are assigned to the slow cooling zone, and the blast vol. set value is increased toward the furnace tail side to give 20+40+60+80=200%, which is combined with 1700% of No.1-17. Accordingly, the outlet strip temp. T0 does not change.
