Three-temperature judgment for electrolyzer
Thread Content
Judgment of the three temperatures in the electrolyzer: The normal temperature ranges for these three components are as follows – 280 degrees for the cathode square steel bar, 350 degrees for the cooling window, and 100 degrees for the temperature of the furnace bottom steel plate. Infrared thermometers are used to measure these temperatures. In daily production, the temperature of all electrolyzers is tested at least three times per month, and electronic records are kept. It facilitates comparison and determination of whether the electrolyzer is damaged. Temperatures in summer are 20 degrees higher than in winter. It helps to make more accurate judgments about the condition of the bath by taking into account the iron and silicon content in primary aluminum.
There are a few questions: 1. Is the temperature measured in degrees above zero or around zero? What is the allowable range of fluctuations? 2. Infrared temperature measurement involves errors, and these errors should be taken into account when using it. 3. The temperature in summer is 20 degrees higher than in winter; is this applicable only in certain regions? Where are you from? The conditions may differ between the north and south of China. 4. Could you provide more details regarding the analysis in conjunction with iron and silicon content?
1. Temperature is the bottom line; a temperature above it is a warning sign. 2. The error has already been taken into account. 3. What is mentioned here refers to the average temperature; of course, temperatures vary from place to place, so this is for reference only. 4. The content of iron and silicon is the best indicator of the problem; an increase in iron alone cannot be taken as conclusive evidence, but if silicon levels also increase, damage is almost certain.
Thank you for your reply. Regarding item 4, could you explain in more detail how to determine it? Is there a certain range?
Let me check; there are dedicated articles on it.
