热力学计算研究浮法玻璃的生产工艺过程

Study of Float Glass Production Process through Chemical Thermodynamic Calculation

浮法玻璃是最重要的玻璃产品,产量大,生产过程涉及的因素众多。本文简述用化学热力学计算分析的方法来研究复杂实际浮法玻璃体系的相转变机理和生产过程,讨论生产的各个阶段和相关的问题,包括:作为研究工具的化学热力学计算分析平台MTDATA和相应数据库及数据测量的介绍;列为各个阶段的硅酸盐反应,玻璃结构的形成,澄清、均化机理,气泡的产生、转化、平衡的规律,耐火材料侵蚀等以及热力学研究在浮法玻璃研发中的现状和问题。

The float glass processing and phase transformation mechanism was approached through chemical thermodynamic calculation considering of the real complex glass composition, whole temperature range, multi-phase constituents including atmosphere conditions in the float glass furnace and the huge scale＇s influence on the surroundings. It is reviewed that the chemical thermodynamic analysis software package MTDATA （developed by National PhYsical Lab, England ） as well as related database as a research implement on the multi-variable silicate reaction process during the float glass manufacture, different glass making process stages, glass forming, refining, bubbling and the furnace refractory corrosion, etc.
