Abstract

PURPOSE:To save fuel which is wastefully consumed by selecting the stack which is lowest in base temp. and raising the temps. of other stacks in conformity with this in the temp. raising process of compound annealing furnace heating groups of objects to be heated. CONSTITUTION:Coils 1 with perpendicularly positioned axes are stacked in 4 steps via convector plates 2 in the stacks S1-S4 in a furnace body 4. In accordance with the initial set values of the furnace and base temps. of a constant input device 13, and the same measured values by thermometers 61, 71, etc. at the start of heating in controlling heating, an arithmetic control unit 12 outputs said set values and measured values, to a fuel control device 141 and the like and the control of the furnace temp. begins. After the start of the heating, the unit 12 receives the measured values of the furnace and base temps. from an input interface 111 and the like upon lapse of a fixed sampling period and selects the lowest base temp. measured value. The unit 12 outputs the prescribed heating pattern to the stack corresponding to the same and the heating patterns corrected to make the base temps. uniform for other stacks to the device 141, etc. Sampling is repeated and while the heating is controlled similarly, the temp. is raised.
