[0002] A heating furnace refers to a device in the metallurgical industry that heats materials or workpieces to the rolling or forging temperature, and can be divided into a continuous heating furnace and a chamber heating furnace.

[0003] When the heating furnace heats the workpiece, generally, an electric heating wire heat source is set at the furnace bottom, and then the workpiece is heated through a heat flow channel. However, this way of heating with electric heating wires has certain limitations. For example, when there are differences in the winding lengths of the electric heating wires, it will lead to differences in the heating power, resulting in uneven heating. In addition, the heating area of the electric heating wire is small. Under the same heating efficiency, the power of the electric heating wire often needs to be very large, which is neither energy-saving nor conducive to popularization and use.
