Embodiment Construction

[0022] Such as figure 1 As shown, the present invention is a furnace for melting high-alkali aluminosilicate glass, the furnace includes a heating system matched with the furnace, and the structure of the furnace includes: a pre-melting pool 1 for melting glass and a A cross-flame melting pool 2 connected to it, in which a kiln ridge 3 for separating the molten glass flow into a melting zone 5 and a clarifying zone 6 is provided. The liquid hole 11 connecting the melting pool 2 and the feeding channel 13 is provided with a stirring unit 16 .

[0023] In the kiln for melting high alkali aluminosilicate glass, bubbles 4 are arranged in front of kiln ridge 3; in the kiln for melting high alkali aluminosilicate glass, kiln ridge 3 and bubbling 4 meet the following requirements:

[0024] h 1 =0.7~0.8H

[0025] h 2 =1.0~1.5H

[0026] h 3 =0.5~0.6H

[0027] Where H is the depth of glass liquid, H 1 is the kiln ridge height, H 2 is the distance from the kiln sill to the bubb...

Abstract

The invention discloses a kiln for melting high-alkali aluminosilicate glass. The kiln is used for manufacturing cover plate glass of a touch screen. The kiln comprises a heating system which is matched with the kiln; the key points are that: a glass kiln structure comprises a pre-melting tank for melting glass, a horizontal flame melting tank which is connected with the pre-melting tank, and a throat which is connected with the melting tank and a material supply channel; and a kiln weir which can divide a zone for accommodating glass liquid flow in the melting tank into a fusion zone and a clarification zone is arranged in the melting tank; and stirring units are arranged in the material supply channel. Energy resources of the kiln are utilized reasonably, the temperature of molten glass rises quickly, homogenization and defoaming efficiencies are high, the high quality requirement of a glass product can be met, and the energy-saving requirement of the kiln can be met.

Description

technical field [0001] The invention belongs to special equipment in the field of glass manufacturing, in particular to a glass kiln for melting high-alkali aluminosilicate glass. Background technique [0002] The chemical composition of high alkali aluminosilicate glass is characterized by SiO 2 and Al 2 o 3 The content is relatively high, which makes aluminosilicate glass have excellent physical and chemical properties, but it also leads to high melting temperature and large surface tension, and the glass clarification process is difficult. [0003] For glass furnaces for manufacturing cover glass products, firstly, high quality glass is required, and secondly, energy saving is required. There are many factors that hinder the high quality of glass, but most of the problems are caused by the presence of air bubbles in the glass and inhomogeneity of molten glass. Ordinary flat glass furnaces have low efficiency, high heat consumption, and unsatisfactory glass clarificati...
