Coking plant

An own coke oven plant provides the necessary coke for pig iron production.

During a process lasting about 16 hours, the volatile components are withdrawn from the hard coal by indirect heating in the 108 coke ovens. The coke oven gas arising in this process is also used in the steel works.
