Description
Technical Field

Background
The annealing process of the metal wire is an important link in the production process of the enameled wire, and the annealing process of the copper or copper alloy wire mainly utilizes higher temperature to restore the changed crystal grains in the wire drawing process to the original state. In the annealing process, after the copper or copper alloy wire rod moving at a high speed passes through the annealing furnace pipe which is heated to the annealing temperature, the annealing effect can be achieved.
However, as the annealing furnace tube can be greatly deformed in a telescopic way in the high-temperature heating process, the annealing furnace tube can be bent, and then the wire passing at high speed is scratched, so that the quality defect and even the product rejection are caused. The existing solution is to fix the annealing furnace tube by using a metal plate, and the bending deformation can be restrained, but the disadvantage is that a larger part of heat of the annealing furnace tube is transmitted to the outside through the metal plate, so that energy is wasted.
