摘要： Disclosed is a coil-annealing spacer which comprises a pair of upper and lower discs, each having a round hole in the central portion thereof, and longitudinal ribs disposed between the discs and secured thereto and extended radially or spirally radially from the round hole of each disc toward the periphery, wherein heat transfer fins are arranged on the inner wall of a gas passage defined by said upper and lower discs and said longitudinal rib along the flow of an atmosphere gas.If this coil-annealing spacer is used, the heating/cooling time is shortened at the annealing step to enhance the manufacturing capacity, and the deviation of the quality in the product coil is reduced.
