Homogenizing effect optimization method for the glass substrate manufacturing stirring system

Abstract

According to the homogenizing effect optimization method for the glass substrate manufacturing stirring system, the geometric model of the stirring system is established by using software, and the fluid simulation model is established according to fluid simulation software, so that the stirring system is obtained, and the homogenizing effect of the stirring system is conveniently achieved through temperature change; an input temperature condition is established in a glass fluid inlet cross section of a stirring system, outlet cross section temperature distribution can be obtained through stirring simulation calculation according to the glass fluid inlet temperature of the stirring system, and different outlet cross section temperatures are measured through different outlet cross sections arranged in the stirring system, therefore, the stirring speed which most conforms to the stirring homogenization effect is obtained. The stirring process and the structure of the stirring system are optimized through a fluid analog simulation means, so that the homogenizing efficiency is greatly ensured, and the actual production line process processing is improved.

Description

technical field [0001] The invention relates to the field of glass substrate manufacturing, in particular to a method for optimizing the homogenization effect of a stirring system for glass substrate manufacturing. Background technique [0002] The glass substrates used in the production of flat panel displays such as TFT-LCD (Thin Film Transistor Display) and PDP (Plasma Display Panel) are manufactured by overflow down-drawing. In the forming process, molten glass melted by a glass melting furnace is supplied to Melt overflow down-draw molding device to manufacture. The chemical homogeneity and thermal uniformity of the glass are key factors in judging whether the glass forming operation is good or not. In the production of liquid crystal substrate glass, the main factor affecting the profit and output of enterprises is glass defects. The main quality defects of substrate glass include bubbles, stones, and streaks. Among them, the bubbles are divided into bubbles caused b...
