Experimental Study on Coal-based Direct Reduction of Shirengou Ore in Open-fired Atmosphere

Using Shirengou ore as raw material, pitch coke as reducing agent, according to the orthogonal experimental theory a experimental study of direct reduction was performed with coke-cover under the condition of open-firing atmosphere. The rational operating parameters of DRI production were obtained. The experimental results also show that DRI product can be produced with Shirengou Ore.
