Maximization of non-coking coal in coal blend is eloquent interest among researchers in
coke making throughout the world. To maximize the non-coking coals in coal blend with the
scarce and expensive coking coals is an essential practice in the iron and steel industry.
The fundamental aspect of the coal blending theory of low value coals to produce good
quality of metallurgical coke in non-recovery coke making process was investigated in this
study by using the composite coking potential technique. The implementation of the
technique has yielded use of up to 25% pulverized coal injection, 20% raw petroleum coke
as a component of coal blend. Results show that the coal blend having composite coking
potential value of \hbox{$\geqslant $}⩾4.8 is desired to achieve the targeted coke strength
after reaction of \hbox{$\geqslant $}⩾65.
