There have been recent developments in EAF-steelmaking in Japan in the quantity and the quality of steel scrap. Generation of scrap is gradually increasing the quantity, but the deterioration of market scrap and the higher requirements for EAF-steel products is making quality more of a problem. Scrap pre-treatment techniques to meet the quality requirements of expanded EAF-steel products, such as blenbing in a busket to control the tramp-elements, shredding to remove non-ferrous contamination etc., have been developed and are being used. The technological interests of most mini-mill are focussed on the better preparation and better utilization of scrap.
