[0002] Industrial hot furnaces are equipment used to heat metal workpieces, usually for various heat treatment processes such as carburizing. Carburizing is a heat treatment process that forms a layer of carbides and nitrides on the metal surface by adding carbon and nitrogen at high temperatures to improve surface hardness and wear resistance. Industrial hot furnaces play a role in heating and controlling the temperature in this process, ensuring that the workpiece completes the carburizing process under appropriate conditions.

The workpieces are fixed at a specific position in the furnace, which may cause uneven heating of the workpieces during the carburizing process, resulting in inconsistent carburized layer thickness and affecting product quality.
[0005] (2) Lack of adjustment of the inner shield and the movable pull plate may cause uneven flow of the carburizing gas in the furnace, resulting in uneven carburization of the workpiece surface, affecting product quality, and may cause poor flow of the carburizing gas, low efficiency of heat energy transfer, and increased energy consumption and production costs.
