[0002] In the metal forging production process, normalizing furnaces are key heat treatment equipment used to heat forgings to the appropriate temperature to improve their mechanical properties and processing performance. However, traditional normalizing furnaces suffer from uneven heating and low heating efficiency, which affects the quality of forgings and production efficiency.

[0003] Currently, most common normalizing furnaces utilize traditional resistance heating or gas heating, regulating the furnace temperature by controlling the power of the heating elements or the gas flow rate. This heating method can easily lead to large temperature gradients within the forgings, resulting in uneven heating and low heating efficiency, which in turn affects the mechanical properties and machining accuracy of the forgings. Furthermore, this low heating efficiency increases production costs and time. Utility Model Content
