Abstract
It was attempted that sintering ore could be used in stead of iron ore (limonite or hematite) for oreing because of iron ores lacking. This sintering ore is made of pyrite cinder or purple ore. Sintering ore was used oxidizing process of cast steel making in the basic electric furnace (capacity : 6 ton). Its result is favcurable and can stand comparison with iron ore. Moreover, sintering ore is superior at several points than limonite. From our studies, it can be co cluded that shown in followings. (1) Decarburizing velocity is about 0.005∼0.008 C % /min by using 10 Kg ore/T molten metal, and is a match for iron ore. (2) Sulpher and cupper contents of sintering ore are free out of plain carbon steel making. Particularly, we gain sulpher content below 0.015% by using sintering ore pyrite cinder and purple ore. (3) Sintering ore does not hold H2O and much powder as limonite. (4) Sintering ore is cheaper price.
