[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The present invention is equipped with a preheating module and a heating module. A high-temperature camera 1, a temperature sensor 1, a high-temperature camera 2 and a temperature sensor 2 respectively monitor the heating conditions and heating temperature of the steel wire material in the preheating and insulation chamber and the heating conditions and heating temperature of the steel wire material in the heating and insulation chamber in real time, and transmit the monitoring data to the temperature control cabinet in real time. The temperature control cabinet automatically adjusts the power of the tubular heating rod, the spiral heating rod 1 and the spiral heating rod 2 according to the preset target temperature and the temperature difference monitored in real time by the temperature sensor 1 and the temperature sensor 2 to maintain the stable temperature in the preheating and insulation chamber and the heating and insulation chamber. The spiral heating rod 1 and the spiral heating rod 2 with different diameters are heated at the same time. The spiral heating rod 2 with a larger diameter is used to provide a stronger heat output, and the spiral heating rod 1 with a smaller diameter is used to provide a finer temperature control. The simultaneous heating of two groups of heating rods with different diameters can improve the flexibility and accuracy of the heat treatment of the steel wire material, so that each part of the surface of the steel wire material is evenly heated, thereby ensuring the uniformity and efficiency of the heat treatment process of the steel wire material, and can solve the problem of how to accurately adjust the temperature change in the steel wire annealing process, thereby improving the effect and quality of the steel wire annealing.

[0034] 2. The present invention is equipped with a fixed tube and a wear-resistant bushing. When the heat treatment device is used, the steel wire material enters the fixed tube from the material inlet, and leaves the fixed tube from the material outlet after uniform heating is completed. The fixed tube is used to support the steel wire material to prevent the steel wire material from being deformed during the heating process. The heating hole 1 and the heating hole 2 opened on the surface of the fixed tube can improve the heating efficiency of the steel wire material, thereby achieving uniform temperature distribution, which is very important for ensuring that the entire steel wire material is uniformly treated. The uniform temperature can also reduce the thermal stress of the steel wire material, thereby reducing the risk of deformation. It can solve the problem of how to prevent the steel wire from heating up too quickly at high temperature, thereby causing local overheating and causing the mechanical properties of the steel wire to decrease. At the same time, the wear-resistant bushing can prevent the steel body, refractory brick layer, aluminum silicate fiber composite insulation layer and thickened insulation layer from being worn when the fixed tube rotates, thereby protecting the steel body, refractory brick layer, aluminum silicate fiber composite insulation layer and thickened insulation layer from damage.

[0035] 3. The present invention injects inert gas into the preheating and heating chambers. The inert gas is one or more of nitrogen and argon. Nitrogen and argon are stable gases that will not react chemically with the steel wire material. Therefore, they can effectively prevent the steel wire material from being oxidized during the annealing process, thereby ensuring the annealing effect and quality of the steel wire material. In addition, the good thermal stability of nitrogen and argon can provide a uniform temperature environment during the heat treatment process, which can help maintain the temperature stability of the preheating and heating chambers, improve the annealing effect, and help achieve more uniform heating, thereby ensuring the consistency of the performance of the steel wire material. It can solve the problem of how to prevent the steel wire from being oxidized during the annealing process, thereby protecting the surface quality of the steel wire. Nitrogen and argon have good thermal conductivity, which can help transfer heat more evenly to each part of the steel wire material, further improving the efficiency of the heat treatment.

[0036] 4. The present invention is equipped with a power module, and starts the transmission motor to drive the fixed sleeve and the fixed tube inside it to rotate, thereby realizing the continuous rotation of the fixed tube outside the steel wire material, so that the steel wire material can be more evenly exposed around the heat source during the heating process, thereby accelerating heat transfer and improving the overall heating efficiency of the steel wire material. At the same time, the rotation of the fixed tube can make different parts of the steel wire material receive heat in turn, which can avoid local overheating or insufficient heating and ensure that the entire surface of the steel wire material is heated evenly. In the traditional static heating method, hot spots and cold spots may appear, resulting in uneven performance of the steel wire material, and the rotation of the fixed tube can effectively reduce this phenomenon, and can solve the problem of how to ensure that the steel wire is heated evenly during the annealing process, thereby improving the annealing efficiency and quality of the steel wire, thereby improving the quality of heat treatment of the steel wire material, reducing energy consumption, and reducing production costs.

[0058] Furthermore, the wear-resistant bushing 15 is located between the steel body 2, the refractory brick layer 3, the aluminum silicate fiber composite insulation layer 4, the thickened insulation layer 7 and the fixed tube 16. When the fixed tube 16 rotates, the wear-resistant bushing 15 can prevent the steel body 2, the refractory brick layer 3, the aluminum silicate fiber composite insulation layer 4 and the thickened insulation layer 7 from wear, and protect the steel body 2, the refractory brick layer 3, the aluminum silicate fiber composite insulation layer 4 and the thickened insulation layer 7 from damage.

[0060] Furthermore, when the heat treatment device is used, the steel wire material 19 enters the fixed tube 16 from the material inlet, and leaves the fixed tube 16 from the material outlet after uniform heating is completed. The fixed tube 16 is used to support the steel wire material 19 to prevent the steel wire material 19 from deforming during the heating process.
