Advanced resource-saving technologies in NLMK's blast-furnace operations

3D model of the dust preparation department

This technology involves co-injecting natural gas and fine coal particles into the blast furnace. Replacing expensive raw materials with cheaper alternatives reduces the cost of pig iron production approximately by 5%.

The ongoing project to implement PCI technology is an integral part of our overall programme to boost operational efficiency and cut costs. The use of this technology on Blast Furnaces No. 4 and No. 5 allowed for 20% reduction in the consumption of expensive coke and more than 50% reduction in the consumption of natural gas.
