One-kiln multi-line float glass production method and device

Abstract

The invention discloses a one-kiln multi-line float glass production method and device. According to the method, part of molten glass produced in a large-tonnage melting furnace is guided to an ultra-thin glass production line through a main cooling part, and the rest is guided to a float glass production line through one or more large paths by means of a branch cooling part. The device comprises the large-tonnage melting furnace, wherein the large-tonnage melting furnace is connected with the ultra-thin glass production line through the main cooling part and further connected one or more large paths which are connected with the float glass production line through the branch cooling part, and temperature and pressure regulators are arranged on two sides of the large paths. The production lines can simultaneously and stably produce glass with different thicknesses and specifications, the production cost for the different specifications of glass is reduced, the energy consumption of each production line is reduced, and product quality is improved.

Description

technical field [0001] The invention relates to the field of float glass production, in particular to a method and device for producing float glass with one kiln and multiple lines. Background technique [0002] The forming process of float glass production is completed in a tin bath with protective gas. The molten glass flows continuously from the furnace through the flow channel and floats on the surface of the relatively dense tin liquid. Under the action of gravity and surface tension Next, the molten glass is spread and flattened on the surface of the tin liquid to form a glass ribbon with flat upper and lower surfaces. After cooling and hardening, it is led to the transition roller table and pulled out of the tin bath into the annealing kiln. After annealing and cutting, the finished glass is obtained. Because it is formed by the float method, it is called float glass. Float glass has become the most advanced production method in the flat glass industry because of its...

AI Technical Summary

Problems solved by technology

This arrangement is more suitable for production lines with little change in glass specifications and large tonnage. The disadvantage is that frequent plate changes will reduce the yield and cannot produce glass with different thicknesses at the same time, especially when producing ultra-thin glass. High energy consumption and difficult quality ensure

Moreover, due to the large amount of molten glass in the large-tonnage melting furnace, the amount of ultra-thin glass produced by the actual single line is relatively small, resulting in excessive and excess glass liquid, resulting in high energy consumption.
