Kind Code:
A1
Abstract:
The invention provides a process for effectively removing slag from molten iron and apparatus therefor. Two harrows fixed at the front-end of cantalever rotate along molten iron level. Solid slag is gripped when two harrows get closer to each other, then harrows draw back to the rim of ladle, which remove slag from ladle. Removal of slag is finished within 3 minutes and removal efficiency of slag is 90% or more. The iron with slag being removed is reduced greatly and the iron loss can be strictly controlled within 0.1 %.
