ArcelorMittal Kryviy Rih Inks Contract With CISDI For BF 9 Upgrade
ArcelorMittal Kryvyi Rih signed an agreement with the Chinese company CISDI to upgrade blast furnace No 9. The contract worth nearly USD 30 million includes engineering design, supply of basic equipment, its supervision, supervision and training staff of the plant. Comprehensive modernization of the DP-9 will allow it to work out the next 20 years, to bring the rate of use of pulverized coal to 200 kilograms per ton of pig iron, to reduce the coke equivalent and to reconstruct the aspiration system, thereby reducing dust emissions to less than 20 milligrams per normal cubic meter and technological gas purification to a level no higher than 5mg / Nm3, which will give an opportunity to radically improve environmental performance. The project also provides for 100% granulation of blast furnace slag with the optimum flow of water to it and obtaining its required quality.
ArcelorMittal Kryvyi Rih has four blast furnaces. "Nine" is the largest of them, its useful volume exceeds 5,000 cubic meters. It produces about half of all pig iron at the steel plant and is still considered one of the largest in Europe. After the modernization of the furnace, its capacity will increase to 10 thousand tonnes of pig iron per day on the existing raw materials and up to 12 thousand tons using sinter and pellets.
ArcelorMittal Kryvyi Rih and CISDI have already begun to prepare the project, a joint design team has been formed, which includes experts from the investment and engineering department of the Krivoi Rog enterprise. 3D-scanning of objects, geodetic and topographic surveys have already begun.
CISDI is part of the Chinese state corporation MinMetals and is one of the world leaders in implementing large-scale engineering projects for the metallurgical industry.
