Reduction of iron ore briquettes into DRI in the tunnel kiln process

We offer third generation tunnel kiln process from China, to convert soft iron ore lumps or briquetted iron ore fines into Direct Reduced Iron (DRI).

DRI or sponge iron is a high-quality metallic product and used as a feed-stock in the induction furnace / electric arc furnace.  The investments on the tunnel kiln plants are 20-25% lower than the Indian rotary kiln plants. The cost of production is also 20-25% lower. Use of coal gas in place of coal makes the tunnel kiln project environmentally clean and safe………. Click here for more details
