Introduction of Energy Efficient Solutions During Cast Iron Smelting at PJSC “NLMK”

The use of coke with hot strength of 60–65% in the blast furnaces of PJSC “NLMK” allowed to increase the intensity of the blast furnace smelting and utilize the efficiency enhancement potential associated with the reduction in specific heat losses, increase in the degree of gas utilization, and increase in gas pressure at the furnace top. As a result, a plant-average coke consumption of 376 kg per ton of cast iron was achieved in 2015.
