Description

Technical Field

[0001] The utility model relates to the field of copper tube well annealing, in particular to a double-layer annealing material rack. Background Art

[0002] In the prior art, the annealing process, as a common metal heat treatment process, is often used for processing copper materials. For example, in order to improve the thermal conductivity and corrosion resistance of copper, the copper is subjected to an annealing process. After setting a specified temperature, the annealing furnace is heated by resistance wires, and then hot air circulation is carried out by a blower to make the copper uniformly heated, so as to improve its metal properties. However, since the copper materials are placed in coils, it is easy to have uneven heating, resulting in an unsatisfactory annealing process effect and affecting its performance. Therefore, it is necessary to provide a material rack for annealing to overcome the above-mentioned defects. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a double-layer annealing material rack. By designing the first-layer material rack and the second-layer material rack, problems such as uneven heating during coil annealing are improved, thereby improving the performance of the coils.

[0004] According to one aspect of the utility model, a double-layer annealing material rack is provided, including: a first-layer material rack and a second-layer material rack placed below the first-layer material rack;
