Abstract

PURPOSE: To prepare a reformed coal suitable as a stock material for producing coke for a blast furnace, by a method wherein crushed low-grade coal is separated into a coarse particle portion and a fine particle portion and, after said coarse particle portion is kneaded with a binder at a specific temp., the obtained mixture is kneaded with said fine particle portion.
CONSTITUTION: A low-grade coal with moisture of 5% or less is crushed so as to reduce the particle size to 2W3mm or less and this crushed coal is separated to obtain a portion of which an integrated proportion from the fine particle side is 5W35% as a fine particle portion (particle diameter 1mm or less) and the remainder as a crude particle portion. Subsequently, to this crude particle portion is added 5W10% of the binder such as coal tar or pitch and kneaded for 5W30min at a temp. range (100W150°C) which is above a softening point of the binder and does not deteriorate said coal. Thereafter, the preliminarily separated fine particle portion is added to this obtained mixture and kneaded.
