Safety problems and solutions in the practice of slag pot for ferroalloy smelting
2017-12-26 | Editor:
During production practice, when using slag pot for ferroalloy smelting, there are mainly the following problems needing attentions:
1. Use a lined liquid iron ladle and three slag pots, sometimes molten iron is too much and will overflow from the ladle to the slag pots, resulting in a sharp rise in the temperature at the bottom of the slag pot, so as to cause damage to the slag pot.
2. Due to the design of the slag pot overflow port, the center of gravity of the slag pot is offset and tilted during the lifting process, and the slag liquid will overflow, which poses a great potential risk.
3. The overall structure of the slag pot is unreasonable, after thermal stress actions, slag pot is likely to crack, and the cracks will result in perforation.
Advised improvement measures:

Advised improvement measures:
1. Thicken the inside wall in the rear of slag pot, to balance the center of gravity after slag pot is lifted.
2. The improvement parts: cancel the upper stiffened edge of slag pot; the thicknesses at the bottom, middle and upper part of slag pot are even; the expansion joints are reserved at the bottom stiffened edge of the slag pot; add stiffener at the bottom of slag pot.
3. Change the structure of the tapping iron car, from a combination of a lined iron ladle with three slag pots into two lined iron ladle with two slag pots, which can effectively prevent molten iron to overflow into slag pots, resulting in local high-temperature damage on slag pots.
