Ultra-thin float glass tin bath

Abstract

The invention discloses an ultra-thin float glass tin bath, which is characterized in that a bath body comprises a bath bottom, side walls, edge seals, breast walls and top caps, wherein the bath bottom consists of bottom bricks; the side walls are respectively arranged at both sides of the bath bottom; the edge seals are respectively arranged on the side walls; the breast walls are constructed above the edge seals; the top caps are arranged above the breast walls through hanging; the inner side of each side wall is provided with lining bricks; the lining bricks are fixedly arranged on the bottom bricks of the bath bottom; and insulation cans are respectively hung on the top caps. According to the ultra-thin float glass tin bath disclosed by the invention, through arranging the lining bricks with different thickness in the bath body, modification can be conveniently performed, so that the tin bath has different inner side widths, and thereby, the phenomenon that the exposure area of tin liquor at the edge parts of glass plates is too big because the tin bath is too wide is avoided, and finally, the manufacturing condition of an ultra-thin glass product is met.

Description

[0001] technical field [0002] The invention belongs to the field of glass manufacturing equipment, in particular to an ultra-thin float glass tin bath. Background technique [0003] At present, ultra-thin float glass is an emerging high-tech, high-value-added high-quality glass. Because of the special requirements for thickness and quality, the structure of the tin bath of its forming equipment is quite different from the traditional tin bath. The volume of the traditional float line tin bath is fixed. For example, the inner width of the wide section of the traditional small float line tin bath is selected according to the shrinkage rate of 2mm glass of 40~50%. The thinner the glass, the greater the shrinkage rate and the wider the wide section. . When producing ultra-thin float glass on a traditional tin bath of a small float line, although the glass is thinner (thickness less than 1.5mm), due to the particularity of the process, the shrinkage rate of the glass ribbon is...

Problems solved by technology

As a result, the distance between the edge of the glass plate in the wide section of the tin bath and the inside of the tin bath is too large, the exposed area of ​​the tin liquid is too large, and the space above the edge is too large, which is likely to cause low temperature at the edge and large lateral temperature difference of the tin bath, directly resulting in ultra-thin glass. The difference in thickness is difficult to control and seriously exceeds the standard
