New Developments in Cokemaking
The cokemaking technology division in a mill in Japan has experienced problems such as price increase and quality deterioration of metallurgical coal, coke oven aging and social demand for environmental friendliness. The Japanese cokemaking industry has struggled to cope with these challenges by developing various new technologies. This paper provides a summary of the recent progress of cokemaking technology such as coal pre-treatment technology for utilizing low-grade, semi-soft coking coal (CMC, DAPS and SCOPE21), diagnosis and repair apparatus for coke oven chamber wall (DOC), and a method to turn waste plastics into chemical raw materials using coke ovens.
