Abstract
Molten ladle metallurgy furnace (LMF) slag is chilled on a chill plate comprising a number of steel slabs disposed side by side. The slag is poured onto the chill plate and allowed to solidify without the application of any water. Solid slag is removed from the chill plate by mechanical means and is eventually reused to make synthetic slag after further cooling, crushing and screening.
Claims6
Method of recovering ladle slag for reuse in a synthetic slag, in which molten ladle slag is discharged onto a substantially planar chill plate, the chill plate having a thermal mass and conductivity which define a heat sink for cooling and solidifying said molten ladle slag into a solid slag without any application of water;
- scraping said solid slag from the chill plate to mechanically dislodge the solid slag;
- collecting dislodged solid slag;
- further cooling dislodged solid slag to ambient temperature without any application of water;
- and
- crushing and screening said solid slag cooled to ambient temperature.
