Description

Cooling water drum assembly for producing high-strength thin glass and tin bath thereof

Technical Field

The application relates to a cooling water drum assembly for producing high-strength thin glass and a tin bath thereof, and belongs to the technical field of novel high-strength glass preparation.

Background

The glass with the thickness of 2.9-3.2 mm is called thin glass, the existing thin glass production method is a float glass production method, and the thin glass produced by the method is poor in strength and low in yield. Especially, the north side part of the glass is easy to bend, and the prior solution is to open the electric heating of the tin bath edge part. But the yield is still low.

The tin bath is one of the core devices in a float glass production line. The molten glass in the tank furnace flows into the tin bath along the flow path at the temperature of about 1100 ℃, and because the density of the glass is only about 1/3 of the density of the molten tin, the molten glass floats on the tin liquid surface and forms a glass ribbon with uniform thickness, namely a glass original plate, in the flowing process. In order to control the temperature of the molten glass in each forming stage in the tin bath, the temperature distribution of the tin bath is adjusted, and the glass is conveniently stretched, flattened, polished, shaped and hardened. Cooling water packs are usually placed in the tin bath to control the temperature in the various forming stages.

The cooling water drum is transversely inserted into the tin bath according to the temperature control requirement in the tin bath, so that the function of reducing the temperature of the glass ribbon is exerted. The quantity of the cooling water bags penetrating into the tin bath is selected according to the requirement of the temperature index of the outlet of the tin bath, however, the quantity of the penetrating cooling water bags is too large, the temperature difference between the edge part and the middle part of the glass plate is increased, and the quality defect of the edge part of the glass is easy to generate.

The existing cooling water drum for the tin bath can not make the temperature of the whole glass uniform, and easily causes the temperature of the edge part of the glass to be too low and the temperature of the middle part of the glass to be high; meanwhile, when the glass is cooled, the temperature of the upper surface of the edge part of the glass is overhigh, and the temperature of the lower surface of the edge part of the glass is low; in one aspect, the glass ribbon is not centerline fed from the tin bath, and these problems result in an inability to mass produce thin glass of acceptable quality, which is prone to edge warping.
