The working principle of a glass tempering furnace is mainly based on the tempering process of glass. During the heating stage, the glass is uniformly heated to near the softening point, causing a change in the internal structure of the glass, an increase in intermolecular distance, and enhanced fluidity. Subsequently, during the rapid cooling stage, the glass surface rapidly cools to form compressive stress, while the interior maintains a higher temperature due to a slower cooling rate, resulting in tensile stress. This balance of internal and external stresses gives tempered glass high mechanical strength and thermal stability.

Glass tempering furnace is a key equipment in the glass deep processing industry, mainly used for tempering glass to improve its strength, safety, and thermal stability. High performance insulation materials and advanced temperature control technology minimize heat loss and reduce power consumption.
