Steel Scrap - an overview | ScienceDirect Topics
Steel scraps are first separated, graded, and sorted into different classes of steel in scrap yards. The scrap yard operator will prepare buckets of scrap according to the needs of the smelter. The scrap is layered in the bucket according to size and density to promote the rapid formation of molten steel in the furnace, and minimize scrap cave-ins, which can break electrodes.
