1.2.2 intermediate and edge deformation temperature difference caused by the glass when the glass is heated in a heating furnace, if the central temperature is higher than the edge of the final glass temperature, the glass in the cooling process, the heat shrinkage of the intermediate portion is greater than the contraction of the cold side portions, eventually the glass is cooled to room temperature and the temperature difference disappears, the edge will be greater than the size of the glass intermediate size, at the edge of the glass of the large compressive stress is formed as a balance this uneven stress, showing saddle-shaped glass. Similarly, a piece of glass is heated in a heating furnace, if the final extension of the temperature distribution in the plane is higher than the central edge portion, the glass in the cooling process, the hotter the glass edge portion is greater than the shrinkage of the middle of the shrinkage of the cooler, the final glass is cooled to room temperature and the temperature difference disappears, intermediate size will be larger than the edge of the glass size, at the edge of the glass to form a larger tensile stress state, to balance this uneven stress in the glass pot-shaped state final presentation, and this states is bidirectional, that is, the middle of the convex glass will change both directions 2.1 for heating roller deformation countermeasures in the front glass and steel rollers allow enough time to warm up, so that the roller is heated evenly, eliminate stress, reduce stress and deformation of the roller. For roller wear, be polished at midnight to clean up the entire roll roller, try to avoid sanding roller part, the roller wear uniform, maintaining the consistency of the roll. And always check to adjust the height of the roller, the roller tracks on the running surface is a plane, in order to maintain the smooth glass surface. Roller grille structure is wrapped around the metal roller surface nylon rope as insulation materials, glass grille in burst easily cut the nylon rope, causing the roller surface uneven, to promptly repair, replace nylon rope.
