Xinhui Carbon technicians rushed to the scene as soon as possible to inspect and analyze the cause and follow up the smelting process.
Analysis:
1. Charging time and power-off time
2. Charge amount and charging method
3. Smelting cycle
4. Waste gas emission and dust removal system
5. Electrode operation and connection
6. Electrode body quality and processing accuracy
7. Strength of electrode joint
Solution:
1. Reduce the damage and breakage caused by mechanical external force, furnace collapse and improper operation. When loading the furnace, large pieces of steel should be loaded in the lower layer of the furnace as much as possible, and the scrap steel should be evenly distributed in the furnace.
2. Select high-quality joints with high strength and good processing accuracy, and avoid mixing multiple products when using them.
3. For smelting furnaces, if conditions permit, the electrode adopts spray cooling technology, which can effectively reduce the oxidation consumption of the electrode side.
