Abstract
Evaluates effects of partial replacement of standard blast furnace coke with pea coke with a grain size from 10 to 245 mm on operation of a blast furnace and on coke consumption rates. Coke abrasion was investigated under laboratory conditions at 1,000 C. Reactivity of pea coke and that of standard blast furnace coke was comparatively evaluated at 900 C, 1,000 C and 1,100 C. Effects of partial replacement of standard blast furnace coke with pea coke were investigated under operating condition in a blast furnace with a volume of 3,200 m[sup 3]. Investigations showed that replacing 8-9% blast furnace coke with pea coke did not negatively influence the permeability of a blast-furnace charge. Pea coke should be characterized by reactivity higher than that of standard blast furnace coke. 3 refs.
