摘要/Abstract

摘要： 玻璃熔体电阻率是设计玻璃电熔窑或电助熔窑的关键参数之一,研究玻璃熔体电阻率测量的边界条件对获得精确电阻率值极其重要。本文基于欧姆定律,构建玻璃熔体电阻率测量装置,探讨了馈入电压、交流电频率、试样颗粒尺寸和填充率等因素对钠钙玻璃熔体在900~1 450 ℃电阻特性的影响。结果显示,当馈入电压为2~10 V,交流电频率为1 kHz,试样颗粒尺寸为830~1 700 μm,填充率为80%,降温速率为2 ℃/min时,电阻率测量结果的误差在各温度段都小于1。该研究可以为玻璃熔体电阻率测量提供参考,进而支撑玻璃电熔窑及电助熔窑电加热系统的设计,实现难熔及易挥发玻璃的熔化。

Abstract: The resistivity of glass melt is one of the key parameters for designing glass electric melting furnace and electric boosting furnace. In order to test the resistivity of glass melt accurately, figuring out the influences of boundary conditions on the resistivity measurement of glass melt is very important. Based on Ohm's law, a glass melt resistivity measuring device was constructed in this work, and the influences of feed-in voltage, frequency of alternating current, particle size of sample and filling rate on the resistivity of soda-lime glass melt at 900~1 450 ℃ were discussed. The results show that when the feed-in voltage is 2~10 V, the frequency of alternating current is 1 kHz, the sample particle size is 830~1 700 μm, the filling rate is 80%, and the cooling rate is 2 ℃/min, the errors of the measurement results of resistivity are all less than 1 in each temperature segment. This work provides a reference for the measurement of glass melt resistivity, which is essential to design the electric heating system of electric melting furnace and electric boosting furnace for refractory and volatile glasse production.

Key words: soda-lime glass, melt, resistivity, electric melting furnace, particle size, filling rate, feeding electricity parameter
