<p><P>PROBLEM TO BE SOLVED: To provide manufacturing methods of a molded product of a ferrocoke raw material and a ferrocoke, which prevent the ferrocoke raw material molded product from softening to fuse and in addition prevent the strengths of the product ferrocoke from becoming lower than those of the conventional ferrocoke. <P>SOLUTION: The manufacturing method of the ferrocoke raw material molded product is provided, which, in mixing coal, an iron ore and a binder to mold in the cold in order to manufacture the molded product, uses an organic binder having a softening point of≤100°C and an organic binder having a particle size of≤0.5 mm and a softening point exceeding 100°C as the above binder. Preferably the organic binder with a≤100°C softening point and the organic binder with a >100°C softening point are mixed, the organic binder with a >100°C softening point is swelled or dissolved and then they are mixed in the coal and iron ore. The ferrocoke raw material molded product is subjected to carbonization to manufacture the ferrocoke. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
