Because of the bright future of the universal requirement for DRI briquette over the next two decades, a new method was created in 2009 in Iran to produce a cold briquette of CDRI (Patent No. IR60923). Cold-Briquetted Sponge Iron (CBSI) was the name given to the new product. Afterward, following pilot-scale and performing various laboratory studies, Cold-Briquetted Iron and Carbon (CBIC) was invented in Iran as a premium product over CBSI because of the prior�¢??s higher carbon content sand higher efficiency through processes of steelmaking (Patent No. IR84090).
Owing to the fact that the cold-briquetting process of DRI is being done under high pressures, the density and mechanical strength of CBIC should be higher and the surface area and also porosity should be less than DRI�¢??s. thus, the oxidation rate, dust and fine generation rate, and the moisture adsorption capacity of DRI will considerably decrease through the process of cold briquetting. These improvements would have big technical, economic and environmental effects on direct reduction and industries steel manufacturing and will push them heading for more sustainability
