Nitrited Low Carbon Ferro Chrome
If the tapping time is properly controlled, it will not only lower the temperature of the furnace bottom, but also reduce the smelting time of high carbon ferrochrome, So in order to ensure the time for ironing, the electrodes will be lowered, and there are three detailed reasons for the decrease in electrodes.
Industrial ferrochrome
1. After opening the tapping hole, as the molten iron gradually flows out, the distance between the electrode and the surface of the intracranial molten iron will increase, the resistance will increase, and the electrode will significantly decrease. This is beneficial for the electrode to descend, thus creating favorable conditions for the next expansion of the crucible and for me to increase the bridge furnace temperature.

2. The electrode generates an arc that emits electrons and has a jet pressure. The lower the electrode descends, the greater its pressure, which can also promote the rapid flow of molten iron and shorten the time for iron production.
3. As the iron is being cast, the crucible will gradually become empty. The electrode should be slowly lowered to prevent material collapse. If the operation is improper and the material collapses during the casting process, it will delay the casting time. As the molten iron flows out and the material level drops, the top of the crucible will gradually press down. At this time, the electrode will also slowly descend, forcing the casting time to decrease.
