There are hot spots on the glass surface, the reason and solution!
[Medium glass] Cause 1: The hot spot on the glass surface is dense orange peel, which is caused by the surface temperature of the glass after the furnace is too high or the heating time is too long. Solution: Reduce the temperature inside the furnace. When making thick glass, the temperature in the furnace should be lowered before entering the furnace. Minimize heating time without compromising glass quality. Reason 2: If the overheating on the glass is star-shaped, it is due to the normal condition of the new furnace at the production stage or the accumulation of the material on the ceramic roll/the original glass is not clean. Solution: Use the waste original plate to carry the dirty things on the waste plate, check whether there is dirt on the furnace glass, and reduce the speed of the glass swinging back and forth in the furnace. If the above can not be resolved, it is necessary to consider the shutdown of the furnace. Nantong Wei Peng Computer Knitting Garments Co., Ltd. , https://www.wpknitting.com
