Glass furnace and glass melting control method

Abstract

The disclosure relates to a glass furnace and a glass melting control method. The glass furnace is provided with a feeding port and a material outlet. The glass furnace includes: a furnace top and a furnace pool bottom; the furnace pool bottom is stepped The structure is used to place the molten glass. The bottom of the kiln pool includes multiple steps, and the depth of the multiple steps increases successively. The depth of each step is the distance between each step and the liquid level of the glass liquid. At least one electrode, the electrode set on each step is located below the liquid level of the glass liquid; the top of the kiln and the liquid level of the glass liquid form a combustion space, and a number of pure oxygen lances arranged in an even distribution are arranged in the combustion space; The inlet is located on the furnace wall at the end of the step with the shallowest depth at the bottom of the kiln, and the feeding port is higher than the liquid level of the glass liquid, and the outlet is located at the furnace wall at the end of the step with the deepest depth at the bottom of the kiln. The feed port is lower than the liquid level of the glass liquid. The disclosure has the effect of making the glass liquid have high uniformity and good quality.

Description

technical field [0001] The present disclosure relates to the field of glass manufacturing, in particular to a glass furnace and a glass melting control method. Background technique [0002] When melting glass, the melting difficulty of various materials in the glass batch is different. For example, when melting special high-alumina and high-alkali glass, the melting difficulty of aluminum in the glass is high, and the melting difficulty of alkali is small, so the melting temperature range spans large . When using the existing glass furnace to melt this kind of glass, due to the unified control of the temperature in the furnace, the melting degree and melting area of ​​the two batch materials are different, resulting in low uniformity of the molten glass after melting. low quality. Contents of the invention [0003] The present disclosure provides a glass furnace and a method for controlling glass melting, which are used to solve the problems of low evenness and poor qual...
