Background
With the development of the technology, electrical equipment such as flat panel displays and the like also develop towards smaller, more compact, lighter and portable directions, so that the ultrathin glass becomes the most indispensable substrate material in the products; the ultra-thin glass is generally referred to as the thickness of common flat glass, the thickness of the thin glass is generally less than 2mm, and the thickness of the thin glass is less than 1.1mm, which is collectively referred to as the ultra-thin glass. Ultra-thin glass with a thickness of less than 0.5mm has good flexibility, while ultra-thin glass with a thickness of less than 0.1mm has bending properties, and may be referred to as flexible glass. In the process of producing ultra-thin glass, three regions, namely, a tooth mark region formed when the edge roller is operated, a clean plate region on the glass plate and a smooth edge region except the tooth mark region, are formed on the glass unfinished product.
In the production process of the ultra-thin float glass, the thickness difference between a smooth edge area outside an embossing area of an edge roller and a clean plate area can reach more than 10 times at most, and the range of the smooth edge area is smaller and is usually in the range of 30-100 mm. Because the thickness difference between the light edge area and the clean plate area is large, the heat dissipation of the light edge area on the glass is slower than that of the clean plate area, and the temperature difference between the light edge and the clean plate glass is large; in addition, because the difference in thickness between the smooth edge area and the clean plate glass is very big and the smooth edge area range is small, the relative position of the smooth edge area can change when producing different specifications of glass, so that the traditional annealing kiln system can not accurately cool the smooth edge area, the cooling transverse position can not be adjusted according to the change of the smooth edge position, and then the temperature of the smooth edge and the clean plate glass has very big difference in the annealing process, and the transverse thermal stress distribution difference of the glass plate is large. This defect makes ultra-thin glass a high technical threshold in annealing processes. The stability of the annealing process operation and the quality of the glass also directly affect the cost and profitability of the glass.
