In the technological process of the steelmaking plant, secondary products are produced in parallel with the production of the main product, which have the character of secondary by-products or industrial waste. The major secondary products of steelmaking production include waste gases, process fluids, flue dust, sludge, slags, and mill scales. The paper presents the results of a research project directed to the utilization of demetallized steelmaking slag and oxygen converter flue dust in the charge of the top-blown oxygen converter. The influence of demetallized slag additions on the slag regime in the converter and the chemical composition of final slag is described and discussed. Recommendations concerning the amount of demetallized slag additions are also presented. Flue dust was recycled in the form of briquettes. No significant effect of recycling the demetallized converter slag and flue dust briquette on the process of hot metal refining and on the quality of the produced steel was recorded. Regarding the achieved results, it can be confirmed that the use of secondary products like demetallized slag and converter flue dust in the form of briquettes is environmentally acceptable as well as the use of natural materials and poses no increased risk to human health or the environment.
