[0002] In the metallurgical industry, a heating furnace is a device that heats materials or workpieces to the rolling and forging temperature. Heating furnaces are used in many industries such as petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals. According to the furnace temperature distribution, the furnace is divided into a preheating section, a heating section, and a soaking section along the length. The preheating section is at the feeding end, where the furnace temperature is lower. Its function is to use the heat of the furnace gas to improve the thermal efficiency of the furnace. The heating section is the main heating section, and the furnace gas temperature is higher to facilitate rapid heating. The soaking section is located at the discharge end, and the furnace gas temperature is very different from the metal material temperature, ensuring that the cross-sectional temperature of the discharged billet is uniform. With the development of society, a feeding device is used when the heating furnace needs to be loaded.
