摘要： PURPOSE:To industrially obtain at a low cost granulated coke useful as a fuel for calcining an iron ore powder, etc. by compounding a coke powder consisting of an intermediate particle portion, a fine particle portion and a coarse particle portion with a cement setting agent followed by roll granulation with adjustment of the water content. CONSTITUTION:A coke powder consisting of not more than 40% intermediate particle portion of particle size 0.5-0.15mm., at least 20% fine particle portion of particle size 0.5mm. is compounded with 3-10% cement setting agent. Then the resulting mixt. is adjusted in the water content to 12-20% and granulated by rolling. More than 40% said intermediate portion remarkably deteriorates the granulatability, so that an enormous amt. of fine particles is necessary for improvement, which makes a prolonged granulation time inevitable. A fine particle of particle size

摘要： PURPOSE:To decrease the inclusion of sulfur contents into an iron or steel bath while providing necessary strength by dividing granulation to a base grain forming period and a shell forming period for forming firm shell layers on the outside of the base grains, and changing the cement formulation in the raw materials used in the respective forming periods. CONSTITUTION:Iron-contg. powder and granules such as rolling sludge, converter dust, powder iron one and the like are so compounded that fine powder components of =80%. A small amt. of cement setting agent necessary for forming base grains and maintaining their shapes is added and these are mixed under controlled humidity so as to contain 11-15% water, after which the mixture is granulated by rolling to allow the contained water to ooze on the surfaces. Said base grains are then rolled in covering powder consisting of iron-contg. powder in a dry state, and a cement setting agent of an amt. necessary for formation of shell layers of required strength, whereby the covering powder is stuck on their surfaces and the shell layers are formed.
