Abstract: In a ferrocoke manufacturing method by shaping and carbonizing a mixture of coal and iron ore, a hardly softening coal having a button index (CSN) of not more than 2.0 is used as the coal. The coal can be a blend of hardly softening coal and easily softening coal, and the hardly softening coal can be a coal having a button index (CSN) of 1.0 and a volatile matter of not less than 17%, and the easily softening coal can be a coal satisfying that a value obtained by multiplying CSN of easily softening coal by a blending ratio of easily softening coal in all coals is a range of 0.3-5.2. The coal can also be a blend of hardly softening coal and easily softening coal, and the hardly softening coal can be a coal having a button index (CSN) of 1.5-2.0, and the easily softening coal can be a coal satisfying that a value obtained by multiplying CSN of easily softening coal by a blending ratio of easily softening coal in all coals is nit more than 5.0.

Abstract: A method for producing ferrocoke in which it is possible to use a cheap and poor-quality coal having a high ash content while suppressing the decrease of the strength in ferrocoke or formed coke and a special coal mixing is not performed with respect to the fusion frequently causing problems in the carbonization with the shaft furnace. In a method for producing ferrocoke by molding and carbonizing a mixture of coal and iron ore, the coal is a single coal or a mixture of plural coals and a non-caking or slight caking coal having a load average value of ash content of not less than 10.7% and a load average value of mean maximum reflectance of not less than 0.81% is used.

Abstract: A method for producing a molded product for ferrocoke, wherein a high-strength molded product for ferrocoke can be produced advantageously without making particular investment in facilities and inviting the operating troubles. In a method for producing a molded product for ferrocoke by molding a mixed starting material of coal, an iron-source material, a high-softening point binder having a softening point of not lower than 150° C., and a low-softening point binder having a softening point of lower than 150° C., at least one of the iron-source material and the high-softening point binder is previously heated to not less than a temperature lower by 20° C. than a softening point of the high-softening point binder to perform molding of the mixture.
