Abstract

Several pilot scale experiments were performed in HADISOLB Company, where different weight ratios of waste and El-Bahareya ores were mixed, then sintered. The chemical composition, physical and mechanical properties of the produced sinter were determined for each set of experiments. As a result, the validity of this novel method was proved.

Highlights

High content of NaCl in the Ironbearing material is considered a threatening factor in the blast furnace process, while that of MnO is only considered as a threatening factor when we come to the stage of steel production
HADISOLB is facing nowadays a big problem which could be expressed as:”to be or not to be!” [21]. It adopts as an integrated company the sinteringBlast furnace-BOF route which necessitates from the first beginning to have a high-quality iron ore to produce high quality sinter ... and so on, and the highest economic indices for each of these steps will be achieved [18,22,23]
This waste obtained from the EZDK Company was delivered to the Egyptian Iron & Steel Company (HADISOLB), where it was stored in an open space, and different mixtures were prepared from it

Summary

Introduction

Sintering of iron ore has been extensively investigated to get better insight into the process [1,2,3,4,5], including study of the use of pellets, sinter, and nut coke charges [6,7,8], thermodynamic analysis [9,10], and measurements and characterization [11,12]. The Egyptian Iron and steel company (HADISOLB) depends for its pig-iron production on the sintering of El-Bahareya ores, whose iron content is < 50%, beside the following impurities: MnO > 2% and chlorides > 0.6%. HADISOLB is facing nowadays a big problem which could be expressed as:”to be or not to be!” [21] It adopts as an integrated company the sinteringBlast furnace-BOF route which necessitates from the first beginning to have a high-quality iron ore to produce high quality sinter ... This waste obtained from the EZDK Company was delivered to the Egyptian Iron & Steel Company (HADISOLB), where it was stored in an open space, and different mixtures were prepared from it.
