The so-called iron outlet burn through, refers to the iron from the iron outlet around (not the iron outlet somewhere) a seam through the place, often burn the furnace case shell and iron equipment, and need to power outages to deal with. Therefore, this accident must be prevented.
Causes of burn-through at the iron outlet:
1 Neglect of the construction quality of the masonry near the iron outlet, especially the poor quality of the brick joints of the carbon bricks.
2 The depth of the long-term plugging of the iron outlet is not enough, or the furnace is often added to lime to treat the furnace conditions, so that the carbon bricks near the iron outlet are seriously eroded.
3 repair iron outlet, electrode paste is not filled, iron from the electrode paste and carbon brick seam through.
4 iron outlet maintenance is not good, the lower part of the depression so that the iron outlet is not easy to plug, iron will be from the bottom of the furnace through the flow of iron trough carbon brick contact between the place of leakage, thus burning through the iron outlet.
Methods to prevent burning through the iron outlet:
1. Pay special attention to the masonry quality of the masonry near the iron outlet when laying the furnace.
2. Iron outlet of the electrode paste should be filled and pounded, so that it is sintered with the carbon brick into one.
3. Maintain the iron outlet and iron flow tank.
4. Try not to use lime to deal with furnace conditions.
5. If the furnace shell near the iron outlet is found to be locally reddened during smelting, it should be dealt with immediately.
Iron outlet burning through the treatment method:
1. Open the iron outlet immediately.
2. Remove the metal and slag from the burnt through part, and then fill and pound it with electrode paste.
3. Repair according to the damage of the iron outlet, if necessary, the power should be shut down, replace the carbon brick near the iron outlet and deal with it in time.
