More Information
Summary: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.
