Description

Technical Field

[0002] Tempered glass is a kind of prestressed glass; usually chemical or physical methods are used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc. Physical tempered glass is made by heating ordinary flat glass in a heating furnace to a temperature close to the softening temperature of the glass (600℃), eliminating the internal stress through its own deformation, and then removing the glass from the heating furnace. Then, high-pressure cold air is blown to both sides of the glass with a multi-head nozzle to make it quickly and evenly cool to room temperature, and then tempered glass can be made.

[0003] The existing glass tempering furnace mainly includes four parts: the glass placing section, the convection heating section, the flat tempering section and the glass taking section. Among them, the convection heating section absorbs the hot air in the furnace and mixes it with the preheated compressed air in the nozzle, so that the temperature of the air flow sprayed from the nozzle to the glass surface is greatly increased. However, the hot air in the existing convection heating section cannot be circulated and heated in time after being blown to the glass, which easily leads to uneven temperature in the furnace, resulting in uneven heating of the glass, affecting the quality and processing effect of the glass, and is inconvenient to use.
