Oct 27, 2011· Slag from the production of ferrochrome is also included here; this material is produced in substantial tonnages and the main use of ferrochrome is in the steel industry. Slags also arise from other processes, particularly the smelting of nonferrous metals, but these materials can be very different and each needs to be studied individually.
For the carbon steel slag, originating from an EAF, three particle sizes were studied (05 mm, 2040 mm, 40185 mm). The ferrochrome slag was crushed and sieved to a 49 mm fraction. The stainless steel slag is a finegrained fraction (< 500 µm) obtained after a crushing, screening and demetallisation treatment. For the characterization
