During glass tempering process, in cases the door of the glass tempering furnace is not opened in time and the heating time is too long, or the primary conveyor of the glass tempering machine stops, or other malfunctions occur, the sheet glass in the glass tempering furnace may melt and solidify on the surface of the ceramic rollers. The proper way to tackle the situation is as follows:
LandGlass B-type bending glass tempering furnace production modes are as follows: 1. Single-station production mode, 2. Multi-station production mode, 3. Continuous production mode.
During the glass tempering process, because of the special properties of the glass coating material, the coated surface of the Low-E glass has higher requirements on the cleaning brushes in the washing machine unit.
The glass sheets placed on the glass tempering machine loading table should be uniform and reasonably spaced, so as to ensure an even distribution of temperature in the furnace chamber and on the ceramic rollers in the chamber.
Because of the ultra-high softening point and extremely low thermal expansion coefficient of high borosilicate fireproof glass, it creates a great challenge for tempering. With the flatness guaranteed, high borosilicate glass must meet the requirement for tempering stress and fragmentation specifications.
To install the ceramic rollers of the glass tempering machine, a roller carrier is to be placed near the position where the rollers are going to be installed.
If the tempered glass bends upward, it indicates that the wind pressure on the upper part of the chiller in the tempering section is lower. You should adjust the wind deflector of the glass tempering furnace downward.
Check the quality of the water in the water tank of the cooling water circulation system every six months. Replace it if the water quality exceeds the acceptable range; acceptable hardness of the circulation water should be: ≤0.03mmol/L.
When the tempering furnace is heated initially, the temperature should be increased by 30~50°C per hour. Depending on the amount of residual moisture in the oven, the tempering furnace will hold the temperature for 2~4 hours at each of the following temperature ranges: 200°C, 300~350°C, 400~450°C, and 550°C.
