The tempered glass will go through cutting, edging, cleaning, tempering, and homogenizing process in the process of tempering furnace processing. How to achieve uniformity and transparency? The following matters need to be paid attention to:

1. It must be ensured that all blowing holes in the quenching section of the tempering furnace are unobstructed and completely transparent.

2. The air ducts of the upper and lower air grilles are guaranteed to be free from damage, air leakage and wrinkles, especially for the air ducts of the lower air grilles. The broken glass slag accumulated on the air duct of the lower air grilles should be cleaned up before production.

3. Ensure that the gap between the aramid ropes wound on the air-cooled roller table is consistent. After heating, when the glass is transported to the air-cooled section, the roller in the air-cooled section also has a certain thermal conductivity, and the contact part of the glass and the roller is quickly cooled*. If the aramid rope wrapped around the roller in the air-cooled section is Inconsistent gaps will also cause uneven cooling of the glass.

4. The apertures of the upper and lower wind grids of the air-cooled section should be the same size, and the surface of the hole wall of the wind hole should be smooth and clean, and there should be no metal burrs. If there is metal burr on the wall of the wind eye hole and it is very rough, the blowing wind will be blocked to a certain extent, and it will also affect the uniform cooling of the glass.
