10 prohibited operations of induction melting furnace
1. Add damp charge and solvent into the furnace;
2. If serious damage to the furnace lining is found, continue smelting;
3. Perform violent mechanical impact on the furnace lining;
4. Run without cooling water;
5. The metal solution or furnace structure is running without grounding;
6. Run without normal electrical safety interlock protection;
7. When the electric furnace is energized, carry out charging, ramming of solid charge, sampling, adding a large amount of alloy, temperature measurement, slagging, etc. If it is really necessary to carry out the above operations with power on, appropriate safety measures should be adopted, such as wearing insulated shoes or asbestos gloves, and reducing the power.
8. Chips should be placed on the residual molten metal after discharge as much as possible, and the amount of input at a time should be less than 1/10 of the capacity of the electric furnace, and it must be evenly input.
9. Do not add tubular or hollow charge. This is because the air in it expands rapidly, which may cause an explosion.
10. There should be no water and humidity in the furnace pit.
