1、 Select a reasonable heating time. The heating power of the tempering furnace is constant. Generally, the heating time is about 35-40 seconds per millimeter of glass thickness. For example, the heating time of 6mm thick glass is about 6 × 38S = 228s. This calculation method is applicable to ordinary flat tempered glass with thickness less than 12mm. When the thickness of glass is 12 ~ 19mm, the basic calculation method of heating time is about 40 ~ 45s per 1mm thick glass.

Do you know the quality of tempered glass is the key?

2、 According to the load of the electric furnace, select a reasonable heating temperature and effectively control the temperature in the furnace. The heating of glass in the tempering furnace mainly includes conduction, radiation and convection. The electric furnace load mentioned here does not refer to the area occupied by the glass in the electric furnace, but refers to the relationship between the glass thickness, heating temperature and heating time.

3、 To achieve uniform heating, the arrangement of glass in the film placing table is also very important. The reasonable arrangement of the flakes is mainly to ensure the uniformity of the longitudinal and transverse loads in the electric furnace, that is, the flake arrangement of each furnace and the gap time of each furnace should be uniform.
