Ferro-coke is an innovative iron making process expected to achieve energy saving by low reduction agent ratio (RAR) operation in the blast furnace. Asphalt Pitch (ASP) was selected as one of appropriate binder to make high-strength ferro-coke. However, it is concerned that ASP will be short of supply in the phase of industrialization. Therefore, it is necessary to develop a new binder to respond to the demand. We have been developing the Hyper-coal (HPC) process, which produces a low ash coal by adopting solvent de-ashing technology. The binder effects between new binder (HPC) and ASP were compared by measuring strengths of ferro-coke in this study. It is considered that the new binder can be applied as the ferro-coke binder to enhance the strength.
