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.
