Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a test device for high-temperature corrosion of electrodes used in glass electric melting furnaces. Background technique [0002] Glass electric melting furnace is a kind of equipment used to melt glass. When the glass electric melting furnace is working, it needs to insert the corresponding electrodes into the glass solution, and then use the Joule effect to generate heat energy, so as to realize the melting of glass. However, after long-term use of the electrode of the electric melting furnace, the surface layer of the electrode will be gradually broken and peeled off due to the long-term erosion and oxidation corrosion of the glass solution, resulting in a decrease in the effective working area of ​​the electrode, reducing the heat generation performance of the electrode, and resulting in glass melting speed.

Problems solved by technology

However, after long-term use of the electrode of the electric melting furnace, the surface layer of the electrode will be gradually broken and peeled off due to the long-term erosion and oxidation corrosion of the glass solution, resulting in a decrease in the effective working area of ​​the electrode, reducing the heat generation performance of the electrode, and resulting in glass melting speed. It is difficult to meet the needs of glass production, which seriously affects the efficiency and quality of glass production

Moreover, different types of electrodes have different corrosion resistance and service life in different glass melting temperature environments. At present, there is a lack of corresponding testing equipment to conduct simulation tests for different types of electrodes under specific operating conditions, so that it is difficult to replace them. Make a reasonable electrode maintenance and replacement plan to ensure production efficiency
