Heat treatment technology is one of the key links to improve the quality of glass molds. It can improve the internal structure of mold materials, improve their mechanical properties and service life, and is of great significance to ensuring the precision, hardness and wear resistance of molds.

[0003] At present, traditional heat treatment uses flame heating, which generates high-temperature flames by burning fuel (such as natural gas, propane, etc.) to directly heat the mold. Although it can meet basic needs, it still needs to be improved in terms of temperature uniformity, energy efficiency and automation. Regarding the above-mentioned related technologies, heating the mold by flame can meet the needs, but at high temperatures, the mold surface is prone to react with oxygen in the air, resulting in the formation of oxide scale.
