ArcelorMittal Kriviy Rih has stopped using natural gas at two of its blast furnaces (##6 and 7) by switching to gasless charge, and thus decreasing the prime cost of pig iron.
“In March both blast furnaces worked with this technology. Thanks to that AMKR became one of the companies in the field to get the best results on prime cost. More over, ArcelorMittal is the only company to use gasless charge on constant basis”, said the company in its statement.
These blast furnaces were chosen because their volumes (2 thousand cubic meters) suited best. After the blast furnaces were switched to the new technology, the oxygen consumption decreased from 70-80 cubic meters per 1 ton of pig iron to just 10 cubic meters. (Ukrainian metal)
