PJSC Novolipetsk Steel intends to boost the quality of its coking coal and drive down costs by implementing the stamp-charging process at its JSC Altai-Koks facility in Siberia.
The new process involves compacting coal outside the coke oven into a briquette, which is then fed into the oven horizontally as opposed to the conventional top-charging method.
The company said June 13 that it is investing €57 million in the initiative. The project is still in the design stage; a full rollout of new equipment is planned for the second half of 2019.
"The upgraded coke plant will be equipped with highly efficient, advanced systems for capturing and treating off-gases, significantly improving the environmental performance of the process," said Konstantin Lagutin, vice president of investment projects at Novolipetsk.
Altai-Koks is using stamping technology at Coke Plant No. 5, which started up in 2006 and covers 25% of Altai-Koks' production requirements.
To rollout the technology across the whole facility, Novolipetsk plans to overhaul the plant, build a storage bunker equipped with stamping machines and install conveyors and machines to load stamped charge into the oven.
