PROBLEM TO BE SOLVED: To provide a plate temperature control method in a continuous annealing furnace capable of controlling plate temperature properly without reducing productivity when controlling the plate temperature in the continuous annealing furnace.SOLUTION: When velocity variation (change of velocity) in a furnace is going to be performed, target plate temperature is corrected unlike a conventional way that performs accelerating and decelerating of furnace velocity, or limits the furnace velocity. Thereby, plate temperature is prevented from being out of without reducing productivity (production efficiency). |
