First of all, 2113 glass is on the iron frame or movable frame 5261. Then break the glass and observe 4102. For example, when 1000 * 3000 is tempered, it is straight after 16glass cutting table machine 53. Then you can look at the long side (3000). If the glass is bent to you, the 3C mark is called up. On the contrary, it is downward.

upwarping is called upward bending, and arching is called downward bending. The reason for upwarping is that the upper temperature is too high and the wind pressure of the lower grille is too high. Solution I: 1. Reduce the upper temperature properly. 2. Reduce the lower wind pressure or increase the upper wind pressure appropriately. 3. Adjust the distance between the air grids properly (bend the upper fan downward, press the upper fan downward, and lift the upper fan upward). In general, the second or third method should be adopted. The results of these two methods are obvious

however, I do not recommend that the temperature of the tempering furnace should not be changed at will. Although it has glass edging machine a range, the experienced steeling operators have their own values, which are the summary of long-term operation.
The wind pressure should not be changed too much, otherwise the particle number of glass will be affected.
The best way is to adjust the height of the upper air grille. If the glass is upward, you will lower the upper grille (the lower grille will not move), otherwise it can.
I hope you can accept it. I have operated the tempering furnace for 6 years. If you have any questions, you can ask me. speak without reserve!



What glass is the original piece of glass, coated or ordinary?
