摘要： PURPOSE: An annealing furnace is provided to anneal a plurality of coils, which should be annealed at different temperatures because of different components, in the same batch by partitioning off the space into a plurality of independent spaces and controlling each independent space under a separate annealing temperature condition. CONSTITUTION: An annealing furnace comprises an annealing furnace body(100), fixed partitions(160a,160b), a coil car(170), and movable partitions(150a,150b). The annealing furnace body charges and anneals a coil. The fixed partitions partition off the inner space of the annealing furnace body and are formed with an opening and a first fastening part. The coil car reciprocates through the opening to transfer the coil into the annealing furnace. The movable partitions are formed to correspond to the opening of the fixed partitions and to be fixed to the coil car, and has a second fastening part to be fastened with the first fastening part. The movable partitions are fastened to the fixed partitions to divide the inner space of the annealing furnace body into independent spaces(110a,110b,110c).
