预处理磨边不好的危害： Hazards of poor tempering in pretreatment of tempering furnace :
1. In the process of heating or cooling of the glass without edging or fine edging, the defects on the side of the glass may be prone to "fryers" or "because of stress concentration or unevenness". "Danger of storm", so the damage to the equipment is also huge.
2. If the glass is not edging or rough edging before entering the furnace, there will be tiny glass slag on the side, and when the device is driven or oscillated, for those tiny sand particles, when the device is rotating It will fall onto the roller table, especially when it is dropped into the furnace. At high temperature, it will be adhered to the ceramic roller table under the rolling of glass, and the glass will also have severely high pits after passing. . If this happens, it will require frequent shutdowns and cooling, which will increase the operating cost of the equipment and affect the service life of the equipment.
3. If the glass without fine grinding is turned on the roller table, it will also cause a certain degree of damage to the surface of the roller table. In particular , the damage to the ceramic roller table of the tempering furnace is irreparable. In this way, for abnormal glass, grooving, or punching, etc., in the process of grinding or chamfering the processed part, it has been guaranteed that there is no burr or crack.
The above are some of the hazards caused by the poor pretreatment and edging of the tempering furnace . I hope it will be helpful to everyone.
