(www.landglass.com) is located in the 12th Luoyang City, Henan Luoyang King City Road, Contact: Mr. Qin II, steel production in the common color of the glass color glass tea glass, blue glass, green glass and the like. The color of the glass, because the color is deep, heated in the furnace to heat absorbed quickly, the glass temperature rises quickly. Production prove the heating time by 5% to 8%, can be mass-produced good quality color glass. Third, the tempered glass glaze glazed glass layer in the surface of the transparent plate glass frit has a specific color by screen or roller printing, followed by sintering, so that the glaze fused with the glass surface an integrally formed decorative effect is very good glass products. In the sintering, while steel processing can be performed. When the steel, under the same heating conditions, since the glass frit darker color, rapid heat, the temperature will be higher than the temperature of the glaze surface side of the non-glaze, baked quenching, if the temperature of the glass on both sides of the upper and lower non- both, will form an unbalanced stress distribution, the glass is warped, deformed or broken. So the glazed glass and steel, you need to set the upper temperature 2 ~ 3 ℃ slightly lower than the lower temperature can, in ensuring burn through the glass case (in which case there may still be uneven glass temperature), look at the actual production conditions, access to good quality toughened glass glaze by adjusting the vertical height of the cooling air gate. 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
