Molten tin bath containing molten tin

Abstract

A molten tin bath containing molten tin is used for float glass production. The molten tin bath comprises a wide section, a narrow section and a contraction section which connects the wide section with the narrow section, wherein the wide section comprises a glass forming section, and the molten tin depth range of the glass forming section is between 28mm and 48mm. The molten tin bath containing molten tin is used for float glass production. The molten tin bath comprises the wide section, the narrow section and the contraction section which connects the wide section with the narrow section, wherein the wide section comprises the glass forming section, and the molten tin depth range of the glass forming section is between 36mm and 40mm, and the molten tin depth range of the contraction section is between 87mm and 91mm. The design of the molten tin depth of the glass forming section overcomes the conventional design bias, a shallower molten tin depth is adopted, and the buoyancy which is generated by the molten tin depth completely satisfies float glass production requirements and can not generate adverse impact on the float glass production.

Description

technical field [0001] The invention relates to the field of float glass production, in particular to a tin tank filled with tin liquid. Background technique [0002] In the production of float glass, the tin bath is a key component, and the tin liquid plays a vital role in the production of float glass. In the existing float glass production, the depth of the tin liquid is relatively deep, and the resulting economic cost is relatively large. First, the amount of tin liquid is very large, and the cost of tin liquid is very high; second, in the production of float glass, the amount of tin liquid is large, and more energy will be consumed for heating and cooling of tin liquid, for example, heating It consumes more electric energy and increases cooling water or air volume during cooling. Third, the impact on the quality of the glass, the deeper the depth of the tin liquid, the greater the temperature difference of the tin liquid, the greater the longitudinal convection of the...

In the existing float glass production, the depth of tin liquid is relatively deep, and the resulting economic cost is relatively large

First, the amount of tin liquid is very large, and the cost of tin liquid is very high; second, in the production of float glass, the amount of tin liquid is large, and more energy will be consumed for heating and cooling of tin liquid, for example, heating Consumes more electricity and increases cooling water or air volume during cooling

Third, the impact on the quality of the glass, the deeper the depth of the tin liquid, the greater the temperature difference of the tin liquid, the greater the longitudinal convection of the tin liquid, and it is easy to produce unpredictable uncertain factors, resulting in the optical properties of the formed glass plate (such as , zebra horns, stripes) become worse, because the convection of the tin liquid is intensified, and the glass plate floating on the tin liquid is also easy to swing in the tin bath, causing various tin bath accidents
