Abstract
PURPOSE: A modified coal that has been made by heating general-grade coal and a binder over the softening point of the binder to fuse them, a binder are incorporated to a low-fluidity coal in a specific proportion, thus producing said metallurigical coke with high strength.
CONSTITUTION: Previously, a general-grade coal and a binder are heated together over the softening point of the binder to fuse them and prepare a modified coal. Then, the resulting modified coal and a binder are incorporated to a low-fluidity coal, thus producing said metallurgical coal. At this time, the mixing ratio of the binder to the low-fluidity coal is given as α, when the strength of the coke becomes maximum; the mixing ratio of the binder to the general coal is given as β, when the strength of the coke becomes maximum; the contents of the low-fluidity coal, the modified coal and the binder are given as X1, X2, and X3 respectively and the amount of the binder and modified coal to be added are determined according to formula I and II and the mixing ratio of the binder in the modified coal and the general-grade coal is regulated by formula III, thus producing said metallurgical coke with high strength.
