INVESTIGATIONS REGARDING UTILIZATION OF POWDER-TYPE FERROUS WASTES FOR HOT METAL PRODUCTION

摘要

The paper analyses the using possibility of the melting schop dust and ferrous concentrates obtained from ashes from the termo-electrical station at the pig iron making in blast furnaces. These ferrous by-products can be used to make pellets which are then used in the furnace charge. Also are presented the pellet characteristics obtained from charges containing melting schop dust and ferrous concentrates from termo-station ashes, in comparison with the pellets from Ukraine. This comparison leads to the conclusion that pellets can be obtained corresponding qualitatively using such charges
