More Information
Summary:A method for the granulation treatment of raw materials for iron making is disclosed, characterized in that a composition for the granulation treatment comprising raw materials for iron making (sintering materials or pelletizing materials) is subjected to a granulation treatment (quasi-granulation or pelletization) by the use of a composition compounded in a manner such that when the composition is dispersed in water at a predetermined proportion, the amount of fine particles floating in water after a predetermined period of time elapsed is 2 wt% or more relative to the solids of the composition used. The method can be suitably used for subjecting raw materials for iron making to a granulation treatment at a low cost, to thereby produce a quasi-granulated or pelletized composition of raw materials.
