              Profiled glass is a new type of architectural glass developed in foreign countries in recent ten years. It is a large long member made of silicate glass. The special-shaped glass is generally produced by calendering method, pouring method and rolling method. In the production process of glass tempering furnace, the tempering parameters of general raw glass are generally set by the engineer of the glass tempering furnace manufacturer. When the special-shaped glass needs toughening, it is necessary to follow the following principles for the setting of tempering parameters of glass:
              1. For the glass with holes and grooves, 2.5% ~ 5% is added at the heating time when the toughening ratio is the same as that of the standard glass.
              2. Sharp angles are used for glass. The heating time of glass with an angle of less than 30 ° is reduced by 2.5% ~ 5% compared with that of ordinary glass heating furnace. These should be treated at the back to prevent corner heat absorption from being too fast, resulting in bending.
              3. As for embossed glass, when the glass is placed, it is generally uneven and upward, so as to avoid ripple caused by too long heating time. Sometimes downward, the heating time is determined according to the thicker part of the glass, and so is the wind pressure.
              4. For endothermic glass, the heating time is generally less than 5% of that of ordinary glass.
              5. For coated glass and heat reflective glass, in order to protect the coated surface, the coated surface shall face upward. The bottom layer temperature and heating time shall be 2.5% ~ 10% higher than that of the general glass with the same thickness.
              6. For glazed glass, it is necessary to be dry before entering the furnace. The upper and lower temperatures are generally set at about 700 ℃. If the glass is bent, the wind pressure should be properly adjusted. The heating balance pressure can be reduced by about 50%. The heating time is related to the glaze color.
