Description

Technical Field

[0001] The utility model relates to the technical field of annealing furnaces, in particular to a temperature-controlled annealing furnace. Background Technique

[0002] An annealing furnace is an industrial furnace used for metal heat treatment, mainly used to change the microstructure of metals through the processes of heating, holding, and cooling, thereby improving their physical and mechanical properties. The working principle of the annealing furnace is to slowly heat the metal workpiece to a certain temperature, hold it for a sufficient time, and then cool it at an appropriate speed. This process helps to eliminate internal stresses, refine grains, improve the metal microstructure, and homogenize the material structure and composition.

[0003] When loading the annealing furnace, the workpiece is manually placed on the placing plate and then pushed into the interior of the annealing furnace. After the annealing treatment of the workpiece is completed, the temperature of the placing plate is relatively high, making it difficult to take out and posing a risk of scalding. To ensure safety, the staff needs to wait for the placing plate to cool down to a safe temperature, thus reducing the production efficiency. Content of the Utility Model

The end of the connecting pipe away from the blower is communicated with an air outlet pipe, and a shunt pipe is communicated with the inner wall of the air outlet pipe.

[0015] Through the above technical solution, after the blower operates, air is conveyed into the air outlet pipe through the connecting pipe, and the inside of the furnace body is blown through several shunt pipes, enabling the heat inside the furnace body to circulate, ensuring uniform temperature distribution, and improving the quality of the workpiece after annealing.
