On October 16-17, ArcelorMittal Kryvyi Rih is hosting the 29th All-Ukrainian Scientific and Technical Conference dedicated to improving the sinter-blast furnace production and the quality of iron ore. The annual conference is held with the participation of specialists from metallurgical enterprises, research and design institutes, as well as leading manufacturers of modern equipment and innovative technologies.
All-Ukrainian conference of blast furnaces and agglomerates is a landmark event in the industry. Every year this forum is held at various enterprises of the country, this year - on the basis of ArcelorMittal Kryvyi Rih. The conference brought together about a hundred participants. Among them are industrialists from Metinvest Holding, Zaporizhstal, Dneprovsky, Enakievsky, Alchevsky, Donetsk metallurgical enterprises, MMK im. Ilyich, Azovstal, Inguletsky, Central, North and South GOKs, Danieli Korus, ArcelorMittal Temirtau, the Institute of Ferrous Metallurgy of the National Academy of Sciences, Krivoy Rog Metallurgical Institute, Mekhanobrchermet and others. The event was organized by the Ukrmetallurgprom enterprise association.
The main topics of discussion were the technical and economic indicators of the operation of blast furnace shops of enterprises in Ukraine and abroad, innovative solutions for the reconstruction of blast furnaces, the experience of introducing the technology of pulverized coal fuel injection into blast furnaces, as well as the determination of the optimal coal base, iron ore part of the charge and quality characteristics of coke for blast furnaces.
Alexander Andrienko, head of the blast-furnace shop, Dniprovsky MZ:
- At the conference, we discuss the most pressing problems for us - raw materials and fuel. This time, more attention was paid to raw materials. At all times, it was unified - the optimal charge and composition were selected for agglomeration or pelletizing of pellets production so that the blast furnace would operate with the best technical and economic indicators. Since I am a blast furnace, I am interested in new directions that concern agglomeration and substitutes for traditional raw materials, all components of the process.
Also, guests of ArcelorMittal Kryvyi Rih were offered an excursion program around the plant. The conference participants got acquainted with the work of the largest blast furnace No. 9 and sinter shop No. 2, where the sinter machines are being reconstructed with the introduction of modern gas cleaning equipment.
Igor Kucher, and. about. Director of the Agglomeration Department of ArcelorMittal Kryvyi Rih:
- Time does not stand still - new developments, technologies, methods, equipment appear. Therefore, it is important for us to be aware of all innovations and offer our own options for solving production problems. Over the past few years, significant changes have taken place at ArcelorMittal Kryvyi Rih. We are constantly working to improve blast furnace production, achieving both economic and environmental improvements. For example, we have mastered the technology of pulverized coal injection at blast furnace No. 9, nitrogen dust suppression systems at the charging devices of blast furnaces No. 6, 7 and 8. The enterprise is undergoing a large-scale reconstruction of the sinter production. Sinter shop # 2 has already upgraded two sintering machines - # 6 and # 5, and at the moment hot tests of the fourth sinter machine are being carried out after its reconstruction. Thus, we are implementing another stage of a large-scale project to modernize the technological equipment of the sinter processing, as well as continue to implement environmental measures.
