requirements of coking coal blending in stockpiling
Hard coking coal to fuel steel growth in India | CRU
Given our assumptions around the average furnace size, the use of stamp charging and prevalence of nonrecovery coke ovens, CRU forecasts the average ratio of hard coking coal to semisoft coking coal in the coking coal blend will increase from 65:35 in 2016 to 84:16 by 2035.
