An innovative cokemaking process, SCOPE21 (Super Coke Oven for Productivity and Environmental enhancement toward the 21st century), has been developed by JISF (The Japan Iron and Steel Federation) and CCUJ (Center for Coal Utilization, Japan). As a cokemaking process, it is important to guarantee safe and stable pushing. Coke pushing behavior was studied by using a pilot-scale coke oven and influence of coking conditions on the Rankin coefficient was investigated. It was found that Rankin coefficient was dependent on lateral shrinkage and fissure density in coke cake and that it can be controlled by controlling the fissure density in SCOPE21 process.
