A continuous annealing device for alloy aluminum wire

Abstract

The invention discloses a continuous annealing device for alloy aluminum wires. The continuous annealing device comprises a basal plate, wherein a hot air bent pipe and a cold air bent pipe are arranged at the top of the basal plate; the cold air bent pipe is arranged at one side of the hot air bent pipe; the hot air bent pipe is fixedly connected with the cold air bent pipe through a connecting pipe; alloy aluminum wires are arranged inside the hot air bent pipe, the cold air bent pipe and the connecting pipe; a first alignment mechanism is arranged inside the connecting pipe; air baffles arearranged at the two ends of the connecting pipe and the bottom end of the cold air bent pipe; a heat insulation plate is arranged between the hot air bent pipe and the cold air bent pipe; second alignment mechanisms are arranged inside the hot air bent pipe and the cold air bent pipe; the hot air bent pipe comprises a first hot air semi-pipe and a second hot air semi-pipe; and the cold air bent pipe comprises a first cold air semi-pipe and a second cold air semi-pipe. By utilizing the loss principle of the temperature of hot air and cold air flowing inside pipelines, slow and uniform continuous heating as well as slow and uniform continuous heat dissipation of the alloy aluminum wires in a conveying process are realized, the annealing effect is better, and the structure is simple.

Description

technical field [0001] The invention relates to the field of annealing devices for alloy aluminum wires, in particular to a continuous annealing device for alloy aluminum wires. Background technique [0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce the hardness and improve machinability; eliminate residual stress, stabilize dimensions, and reduce deformation and cracks Tendency: refine the grain, adjust the structure, and eliminate the defects of the structure. At present, the annealing method adopted by various cable companies to produce alloy aluminum wires is a relatively simple well-type furnace annealing method. This method has many defects: the process is relatively backward, and the energy consumption is large; If the temperature in the direction is not uniform, there will be uneven softness and...

At present, the annealing method adopted by various cable companies to produce alloy aluminum wires is a relatively simple well-type furnace annealing method. This method has many defects: the process is relatively backward, and the energy consumption is large; If the temperature in the direction is not uniform, the softness and hardness of the inner and outer wires will be uneven; a large number of wires will be annealed in a well-type furnace, and the surface of the wire will have color difference, and even wire bonding may occur
