COMPOSITION FOR COKE PRODUCTION, MOLDED COAL, COKE FOR BLAST FURNACES, METHOD FOR PRODUCING COKE FOR BLAST FURNACES, COMPOSITION FOR IRON-MAKING STARTING MATERIALS, MOLDED PRODUCT FOR IRON-MAKING STARTING MATERIALS, IRON-MAKING STARTING MATERIAL FOR BLAST FURNACES, AND METHOD FOR PRODUCING IRON-MAKING STARTING MATERIAL FOR BLAST FURNACES

摘要

This composition for the coke production contains coal and a binder material; and the binder material contains a binding filler that uses ash-free coal as a starting material and a strength retention material that uses ash-free coal as a starting material and has a lower softening starting temperature than the binding filler. A composition for iron-making starting materials according to the present invention contains coal, iron ore and the above-described binder material.
