Abstract
In view of shortage of coking coal supply in future, it has been expected to establsh the processes which could use non-coking coal for making of metallugical coke.
At first, four main technices which is anticipated to be available for this intention were described in outline. Secondary development of D. K. S formed coke process and SUMICOAL-system which consist of the use of special caking substance, ASP, and the method of briquette blend were elucidated, D. K. S process is not continious, but has reached to possible step could prduce formed coke in commercial.
SUMICOAL-system has consumed non-coking coal over one million ton age for the past year, and its coke quality was confirmed to even to conventional coke, through results of laboratory testes and 5, 000m3 class B. F operation.
