Nizhniy Tagil Iron and Steel Works (NTMK), subsidiary of the Russian iron ore and steel producer Evraz Group, has completed the first phase of its experimental program which is aimed at reducing the use of coke in pig iron production.
During the first phase of the program, NTMK partially supplemented coke with energy coal. As a result of the testing, the use of coke was reduced to 7.6 kg per one metric ton of pig iron while use of energy coal was increased to 10 kg per one metric ton of pig iron.
As its next step, NTMK is planning to increase use of energy coal to 20 kg per metric ton of pig iron and therefore further decrease the use of coke.
The program will allow NTMK to reduce its primary cost of production.
