Electric arc furnace---how to do the maintenance arc melting furnace

How to do the maintenance of electric arc furnace?  

Electric arc furnace is a large-scale steelmaking equipment, the later maintenance and maintenance work directly affects the efficiency of steelmaking, so how to do the maintenance and maintenance of electric arc furnace?  

Standardized operation steps for improving maintenance mode

1. Intuitively confirm the melting loss of refractory materials in each furnace to ensure the safe operation of the furnace.  

2. Formulate the standards for the maintenance of furnace wall and bottom, standardize the standardized operation of maintenance, especially the use standards of spray filling materials, which must be used in accordance with the amount specified in the standards (reasons must be indicated in special cases).  

3. Increase the number of cold filling and control the bottom electrode reaming.  

4. Blow the residual steel slag at the bottom electrode to reduce the amount of slag at the bottom electrode and ensure the quality of furnace repair.  The new maintenance process was adopted to purge the molten steel during the hole reaming of the bottom electrode, and then the hot repair was carried out, which effectively controlled the hole reaming of the bottom electrode and ensured the repair effect of the hole reaming of the bottom electrode.  After each cold filling, 1t carbon powder is placed in the middle of the bottom of the furnace to strengthen the sintering effect of the bottom material and ensure the conduction.
