When glass heating temperature exceeds the softening point, the glass can be easily deformed, and significant damage will be caused to the surface quality of tempered glass.
Glass with poor edging tends to blast during the process of heating or cooling due to excessive concentration or uneven distribution of stress caused by edge defects. This may lead to significant damage to the glass tempering furnace.
During tempering process, in cases where the furnace doors are not opened in time, heating time is too long, the conveyor is stopped or encountering other mechanical malfunctions, the glass may get stuck to the ceramic rollers of the glass tempeirng furnace. The proper way to handle the situation is as follows:
What type of glass tempering furnace is the best choice for tempering ultra thin PV glass?Continuous Tempered Glass Machine of LandGlass will be your best choice for tempering ultra thin PV glass.
By adopting LandGlass’ Adaptive Compensating System, the impact on the quality of tempered glass due to ambient temperature fluctuation can be eliminated effectively.
To ensure the smooth lifting of the furnace, the trapezoidal lead screw rods inside the pillars need be lubricated with N46 oil after every lift (or at least once a month). Apply lithium grease to the bevel transmission gears once every quarter.
When the optical effect of the glass is less than desirable or there is a spontaneous explosion inside the furnace cavity, the tempering furnace should be turned off promptly.
The loading table of LandGlass tempering furnace is equipped with a machinery foot switch, which serves as an adjusting micro-inching unit during placement of the glass in the furnace.
Spontaneous explosion tends to occur to tempered glass and the following reasons account for it:1. There are nickel sulfide particles in the glass sheets;2. The stress of the tempered glass is too high.
