Abstract
The oxidation of sponge iron products and its destructive effects on iron content as well as other properties have been considered by ferrous technologists for a long time. In this investigation, a unique new low temperature method of preventing and/or retarding the oxidation of direct reduced iron is introduced. Experimental results from laboratory and pilot plant tests show the success of the method which has been named cold briquetting of sponge iron. The optimum condition for briquetting is achieved at 80 kN (Lcm)-1, 6% binder, 10% sponge iron fines and 4% anthracite. While hot briquetted iron has become a successful method for the new generation of iron reduction plants, cold...

Abstract
In the present paper, the effects of charging of Cold-Briquetted Iron and Carbon (CBIC) into the electric furnace on the steelmaking operating parameters was investigated and compared to the performance of Cold Direct Reduced Iron (CDRI) and Hot-Briquetted Iron (HBI) as the other products of Direct Reduced Iron (DRI) family. The efficiency of the carbon charged through CBIC compared to free-charged carbon into the steelmaking furnace was also evaluated. The results revealed that although the energy consumption of CDRI is somewhat lower than CBIC, the Fe yield content of CBIC is higher and its tap time is lower than CDRI which may improve the productivity of industrial steelmaking plant....
