Restored at a cost of $48.5 million, the new battery nearly triples capacity to 470,000 metric tons of coke annually. The highlights of the upgrade include an automated workflow control system and improved safety and environmental protection measures. The No. 6 launch will allow Mechel-Coke to begin reconstruction of coking battery No. 5 while increasing production volumes by 5% in 2011 compared to the same period last year.
