What is the high yoke temperature of steel shell furnace?
Red yoke of steel shell furnace is a common fault phenomenon. If there is no problem in the circulation of cooling water, it can usually be solved from the following aspects:
1. The yoke of medium frequency furnace is aging and the interturn coating is seriously corroded. Solution: Open the silicon steel sheet for surface coating treatment.
2. Stick molten steel (iron filings) on the yoke. Solution: Grind the yoke to remove adhered iron filings.
3. If the fault phenomenon still exists after the above treatment, try to adjust the overheated yoke to a position close to the furnace nozzle for installation.
4. Check the thickness of the furnace bottom. Too thick a furnace bottom will also cause the yoke to heat up and become red.
