Heat source for baking electrode paste
The electrode paste is sintered in the electrode shell, and its heat source comes from three aspects:
1. Electric heating itself conducts heat. The temperature of the electrode tip can reach 3,500 due to arcing. About C, because the heat conducts from bottom to top, the electrode paste is heated more and more when it falls from the top to the top, and it is gradually sintered. The conduction of arc heat is the main source of heat required for firing the electrode.
2. The resistance heat generated by the current passing through the resistance itself. When the current flows through the electrode, due to the large sintering resistance of the electrode paste, part of the input power becomes resistance heat, which provides a certain amount of heat for the firing of the electrode.
3. The conduction and radiation of flame heat on the charge surface. The temperature of the stove surface is very high, generally between 500 and 600. About C, its heat can be conducted and radiated to the electrode, especially after the electrode is lowered, the surface temperature of the electrode increases rapidly, which has a lot to do with the complete sintering of the electrode.
