Description

Technical Field

[0001] The utility model relates to the technical field of annealing furnaces, in particular to a continuous annealing furnace for producing copper and aluminum. Background Art

[0002] In the field of metal processing, especially in the refining and modification of copper and aluminum materials, continuous annealing furnaces play a crucial role. The annealing process aims to improve the microstructure of materials through heating and cooling processes, thereby enhancing their mechanical properties and electrical conductivity. However, the continuous annealing furnaces in the prior art have significant defects in temperature control, which directly affect the final quality of materials and production efficiency, becoming a major bottleneck restricting the development of the industry.

[0003] The core of a continuous annealing furnace lies in its ability to provide a stable heating environment, enabling materials to undergo necessary heat treatment within a set temperature range. However, the temperature control mechanisms of traditional annealing furnaces often fail to achieve highly precise temperature regulation. Due to the non-uniformity of the temperature distribution inside the furnace and the errors in temperature sensors and control systems, there is a deviation between the actual heating temperature and the set target. This deviation is not limited to the contingency of a single measurement but systematically runs through the entire heating cycle, causing materials to complete the annealing process under non-optimal conditions.

[0004] The inaccuracy of temperature control is directly related to the microstructure changes of materials during the annealing process. For copper and aluminum materials, the laws of grain growth, phase transformation, and stress release are different at different temperatures. Temperature fluctuations or inaccuracies will destroy the uniformity inside the materials, leading to abnormal growth of local grains or the formation of unwanted phase structures, ultimately affecting the mechanical properties and electrical conductivity of the materials. In addition, the uncertainty of temperature control may also result in inconsistencies in the material properties between batches, increasing the risks of downstream product processing and application.

[0005] In addition to the negative impact on material properties, the inaccuracy of temperature control also has a double blow to production efficiency and energy consumption. To compensate for the inaccuracy of temperature control, producers are often forced to adopt conservative strategies, that is, extending the annealing time and increasing the heating power to ensure that all materials can meet the minimum annealing requirements. Although this method makes up for the deficiency of temperature control to a certain extent, it also significantly increases the production cost, including additional time costs and energy consumption. In the long run, this not only reduces the economic benefits of enterprises but also poses challenges to environmental protection.

[0006] The problem of the accuracy of temperature control in continuous annealing furnaces has become a key obstacle restricting the development of the copper-aluminum material processing industry towards higher quality and more efficient energy. In today's highly competitive global market environment, any technological innovation that can improve material properties, reduce costs, and save energy and reduce emissions will become a source of competitive advantage for enterprises. Therefore, developing a new technology that can achieve precise temperature control in continuous annealing furnaces can not only solve the core problems in the current annealing process but also promote technological innovation and industrial upgrading in the entire metal processing industry.

[0007] Therefore, how to provide a continuous annealing furnace for producing copper-aluminum is an urgent problem to be solved by those skilled in the art. Utility Model Content
