PROCESS FOR PRODUCTION OF COKE AND PROCESS FOR PRODUCTION OF PIG IRON

摘要

The invention provides a process for the production of coke which brings about an improvement in the strength of coke or which permits simplification of the humidity control step substantially without lowering the strength of coke; and a process for the production of pig iron by using the coke obtained by the process, more specifically, a process for the production of coke by loading coal into the carbonization chamber of a coke oven and carbonizing the coal which is characterized in that the coal to be loaded into the carbonization chamber is a mixture of 100 parts by mass of coal for coke making with at most one part by mass of substantially ash-free coal; and a process for the production of pig iron which is characterized by using a coke obtained by the above process for the production of coke.
