説明
In this study, sources of steel scraps for electric furnace steel products were investigated as fundamental data for studies aiming at improvement of recycling of steel.<BR>The amounts of steel scraps generated in 2001 were divided into heavy scrap processed by guillotine (58.7%), shredded scrap (7.2%), pressed scrap (3.4%), koudarai scrap (6.9%), shindachi scrap (17.6%) and others (6.2%). Then, the mixing ratios of various kinds of steel scrap and pig iron for raw materials of electric furnace (EF) were estimated. It was found that the mixing ratio of the steel scraps was dependent on steel products, and hence different in three groups ; family EF companies of blast furnace (BF) steel makers, mild steel EF makers and special steel EF makers. For example, the BF family companies produced mild steel (21.6%) and special steels (78.4%) by employing the mixing of 42.2% inhouse scrap, 15.3% heavy scrap, 19.8% shindachi scrap, 7.4% koudarai scrap and 1.3% pig iron for the raw material.
