The utility model has the advantages of simple structure, practicality and convenience, high reliability and stability, and fills the blank of this kind of measuring equipment and measuring method.
Description
technical field [0001] The invention belongs to the field of glass manufacturing, and relates to a test device and a method for testing the high-temperature corrosivity of electrodes used in glass electric melting furnaces. Background technique [0002] Due to its high efficiency, high quality, less pollution and easy automatic control, glass electric melting furnaces have developed rapidly in my country in recent years. According to the conductive properties of molten glass ions in the existing electric melting furnace, the electrodes are immersed in the molten glass, and the Joule effect is used to convert the electric energy into heat energy inside the carrier to realize the melting of the glass. When the glass electric melting furnace is used in the middle and late stages, due to the erosion and oxidation of the glass liquid, the top of the electrode becomes sharper and shorter, the surface area of the electrode in the glass liquid becomes smaller, and it is difficult ...
