Glass tempering furnace and glass tempering method

A glass tempering method, applied to a glass tempering furnace which comprises a preheating furnace section, a heating furnace section provided with a plurality of infrared burners, a soaking furnace section disposed after the heating furnace section along a glass traveling direction, and a plurality of drive rollers passing through the preheating furnace section, the heating furnace section, and the soaking furnace section in sequence, and comprising:

• manually or automated device laying a glass in a single layer of the glass on a material layout platform to place products;
• carrying the glass on the plurality of drive rollers to the preheating furnace section and preheating the glass in the preheating furnace section, wherein the preheating furnace section has a feed port, a general smoke vent is disposed at the feed port, and the preheating furnace section is divided into a plurality of sections along the glass traveling direction, wherein each section of the plurality of sections has a smoke suction port and a smoke ejection port;
• carrying the glass to the heating furnace section and heating the glass in the heating furnace section to a set temperature of 600° C. to 640° C., wherein each of the plurality of infrared burners is a porous medium burner, and each section is configured to suck smoke from the heating furnace section through the smoke suction port and deliver the sucked smoke to the preheating furnace section through the smoke ejection port;
• and
• carrying the glass from the heating furnace section to the soaking furnace section and heating the glass and homogenizing a temperature of the glass by circulating gas sweeping across upper and lower surfaces of the glass, wherein a plurality of air ducts are disposed in the soaking furnace section and configured to generate horizontally parallel airflow on the upper and lower surfaces of the glass.
