ArcelorMittal Kryvyi Rih was visited by CISDI specialists – suppliers of technology and basic equipment for the reconstruction of blast furnace No. 9

Kryvyi Rih, March 23, 2021 ArcelorMittal Kryvyi Rih welcomes guests – specialists from the Chinese company CISDI, which is a partner in the implementation of a key investment project. An agreement on the reconstruction of the largest blast furnace at the enterprise No. 9 worth $ 30 million was signed in 2019. It includes the development of engineering, the supply of main equipment, supervision of installation and commissioning, as well as training of the steel mill personnel. Yesterday, March 22, representatives of the Ukrainian companies STEM and M.Technology, which are CISDI’s subcontractors in the modernization of the furnace, also took part in a welcoming meeting with Chinese specialists. CISDI is part of the MinMetals state corporation of China and is one of the world leaders in the implementation of engineering projects for the metallurgical industry. A meeting with partners at the ArcelorMittal Kryvyi Rih production site was planned at the first stages of the project discussion. But last year it had to be postponed due to “due to the COVID-19 pandemic and tough quarantine restrictions around the world. As a result, the project schedule was revised and re-approved jointly with CISDI. The specialists of the Chinese company will spend about three months in Krivoy Rog to complete basic engineering, preparation of the “project” stage and the ATS report. Dong Long, Project Manager, CISDI, China – Our goal is to implement everything planned, to make the project as efficient as possible. We have many tasks before us, however, we have a large team of highly qualified specialists, capable of covering the entire technological process of the blast furnace. We have already visited the “maidens” tent, and got to know about the “objects of the complex”. Grateful to ArcelorMittal Kryvyi Rih for the warm welcome and good organization. Goutam Pinapotu, project manager for the reconstruction of blast furnace No. 9, ArcelorMittal Kryvyi Rih – reconstruction of blast furnace No. 9 will allow us to present a new technology in the production of pig iron – we will build a modern blast furnace that will fully comply with environmental standards … Our Chinese partners have a wealth of experience in the implementation of such projects. This is a truly professional team. The result of our joint work will be successful, we will make every effort for this. ArcelorMittal Kryvyi Rih has four blast furnaces. “Nine” tents “is the largest of them, its useful volume exceeds 5000 cubic meters. It produces about half of all pig iron at the plant and is still considered one of the largest in Europe. Comprehensive modernization of blast furnace No. 9 will allow it to efficiently operate the next 20 years, to achieve the maximum level of use of pulverized coal (up to 200 kg per ton of pig iron), to reduce the coke equivalent (total fuel consumption – gas, coal and coke) and, accordingly, to reduce the cost of pig iron. As a result, it was decided to upgrade the aspiration system using bag filter technology and install two new axial cyclones instead of the currently operating dust collectors. to normal cubic meter (mg /Nm3), and technological gas cleaning – up to a level not higher than 5 mg /Nm3. This will significantly improve environmental performance. The project also provides for one hundred percent granulation of blast furnace slag with optimal water consumption using modern dewatering drum technology. As a result of the modernization, a new blast furnace shell with an increased thickness, a modern refractory lining of a furnace hearth with a ceramic glass, a new closed-type cooling system using copper cooling plates, as well as cast iron refrigerators will function. A flat casting yard with new equipment will be in operation: hydraulic machines, a coneless loading device and probes for measuring the level of the charge. By this time, ArcelorMittal Kryvyi Rih had already completed a large order of new equipment from leading international companies: machines for the foundry yard manufactured by DHM, furnace casing from Danieli Corus, furnace top from CISDI, carbon block from Takoi COBEX, foundry yard and aspiration system for warehouse premises from Sinosteel. The company is also negotiating with various local and international contractors to carry out construction work. Thanks to the modernization of the furnace, its capacity will increase to 10,000 tons of pig iron per day using existing raw materials and 12,500 tons using sinter and pellets. ArcelorMittal Kryvyi Rih plans to produce pellets after the construction of a modern pelletizing plant. The declared capacity of the new plant will be up to 5 million tons per year. The pellets will be used as raw materials for blast furnaces,
