[0002] Tempered glass is a tempered glass with high safety, high strength and thermal stability obtained by cutting ordinary annealed glass into required sizes, heating it to about 700 degrees, close to the softening point, and then cooling it quickly and evenly. In the existing glass tempering furnace, the glass raw materials are fed into the furnace body of the tempering furnace through a high-temperature resistant conveyor belt. The furnace body is heated by an electric heating wire to form a furnace temperature of nearly 700 degrees to heat and soften the glass raw materials on the high-temperature resistant conveyor belt. However, during the heating process, the upper surface of the glass raw materials is facing the electric heating wire and the lower surface is close to the high-temperature resistant conveyor belt.
