Abstract

The invention provides a cylinder type annealing furnace, and belongs to the field of heat treatment equipment. The cylinder type annealing furnace comprises a furnace body and a furnace cap, wherein the furnace body comprises a furnace side wall and a furnace bottom wall; a first insulating lining is arranged in the furnace side wall, a refractory lining is arranged in the first insulating lining; the furnace cap covers the first insulating lining; a second insulating lining is arranged on the upper surface of the furnace bottom wall; a first resistance wire is arranged on the refractory lining; and a vertical tube is arranged in the furnace body, and a second resistance wire is arranged in the vertical tube. According to the annealing furnace, an inner ring aluminum conductor and an outer ring aluminum conductor can be heated at the same time, so that same hardness of the inner and outer ring aluminum conductors after annealing treatment can be guaranteed.

Description

technical field [0001] The invention relates to the field of heat treatment equipment, in particular to a caisson type annealing furnace. Background technique [0002] Annealing is a metal heat treatment process, which refers to heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed to achieve the purpose of reducing the hardness of the metal. When the aluminum conductor is annealed, it is generally necessary to wind the aluminum conductor on the annealing disk, put the aluminum conductor and the annealing disk together into the annealing furnace, and perform annealing treatment. During the annealing process, the aluminum conductor wound on the outer ring The heat is faster, and the aluminum conductor wound on the outer ring is heated slower. After the annealing treatment is completed, the hardness of the aluminum conductor of the inner ring and the aluminum conductor of the outer ring will be different. To ...
