Glass substrate smelting furnace

Abstract

The invention discloses a glass substrate smelting furnace which comprises a smelting furnace body (5). The smelting furnace body extends forwards to form a pre-smelting pond (1). Two feed inlets (2) are symmetrically formed in a front breast wall of the pre-smelting pond. A left breast wall and a right breast wall are each provided with a burning lance (3), and a smoke outlet (4) is further formed in the upper portion of the front breast wall. The pre-smelting pond is additionally arranged on the front side of the smelting furnace body, batch can be pre-smelted at high temperature firstly through the burning lances, and heated and pre-smelted liquid glass flows into a smelting pond of the smelting furnace body and only needs little energy to obviously improve smelting quality; meanwhile, the feed inlets are formed in the front breast wall of the pre-smelting pond, temperature influences of a material pile formed by the accumulated batch on the smelting furnace body can be reduced or even eliminated, and the material pile only fluctuates in the pre-smelting pond and does not affect the temperature of the smelting pond of the smelting furnace body. Process stability is guaranteed, and a good foundation is provided for product quality.

Description

technical field [0001] The invention relates to the technical field of glass substrate production, in particular to a glass substrate melting furnace. Background technique [0002] With the advancement of science and technology, the electronic products and equipment required by the society have developed rapidly. With the rapid development of electronic glass, the market demand for glass substrates is increasing year by year. In the production of glass substrates, the pool furnace is a key process at the hot end. , the importance of its process stability is self-evident. [0003] In the production of glass substrates, the function of the furnace is only melting, and clarification, homogenization, and cooling are all tasks of the subsequent processes. The primary task of the kiln process is to provide molten glass with stable temperature and uniform composition for the subsequent process. [0004] Generally, furnaces with small size and limited melting area are usually used...

AI Technical Summary

Problems solved by technology

Due to the relatively small melting area of ​​the kiln, the spiral feed feeding point is concentrated and close to the pool wall bricks, and it is easy to form accumulation at the discharge point, and push the melting toward the kiln. The collapse of the accumulation during the advancing melting process will cause The raw material mountain is unstable, resulting in temperature changes in the kiln, affecting process stability and product quality
