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、关于有孔有槽的玻璃，在增韧比相同标准的玻璃加热时刻添加2.5%~5%。

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、玻璃用尖利的角，不到30°角的玻璃比一般玻璃加热炉加热时刻削减2.5%~5%，应该把这些放在后边处理，为了防止角落热吸收太快，导致弯曲。

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、关于压花玻璃，当玻璃被摆放时，一般是不平整向上的，以免加热时刻过长造成波纹。有时向下，加热时刻根据玻璃较厚的部分来决定，风压也是。

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、关于吸热玻璃，加热时刻一般小于一般玻璃的5%。

4. For endothermic glass, the heating time is generally less than 5% of that of ordinary glass.

5、关于镀膜玻璃和热反射玻璃，为了保护镀膜外表，镀膜外表要朝上。底层温度和加热时刻要比一般玻璃厚度相同的情况下添加2.5%~10%。

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、关于上釉玻璃，进炉前有必要枯燥，上、下温度一般设置为700℃左右，如果玻璃弯曲，要恰当调节风压，加热平衡压力可下降50%左右，加热时刻与釉面色彩有必定的联系。

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.
