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 priorÃ?Â¢??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 DRIÃ?Â¢??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

Cold Briquetted Iron (CBI)

Cold Briquetted Iron (CBI) is defined as DRI which has been molded at a temperature less than 650 Ã?Â°C or with a density of less than 5000 kg/m3. Due to the raw material sharp shortage for steelmaking in many countries worldwide, a need arises to find a substitute material to replace the rare pig iron and expensive steel scraps that were used by steelmaking plants. 1- More density and less porosity The apparent density of CBI is about 8.3 grams per cubic centimeter and the density of DRI is about 2.3 grams per cubic centimeter. On the other hand, the volumetric porosity of these two products is about 30 and 50%, respectively. These two factors reduce the environmental reactivity of CBIC and its lower transportation costs. 2- Less fine The wear resistance and higher mechanical strength of CBI compared to sponge iron causes less softening to occur during the handling of the product, and as a result, both the economic value of the product is prevented and the charge losses of the product in the steelmaking furnace are prevented. is significantly reduced. 3- Easier to store and carry Due to the lower reactivity of CBI compared to DRI, the loss of metal grade of the product during storage and transportation is significantly reduced, which will reduce the amount of economic value loss of the product from the time of production to the time of use in the steelmaking furnace. On the other hand, sea transportation of CBI leads to a reduction in transportation costs compared to DRI due to the absence of the need to apply neutral gas to prevent product activation. 4- More thermal and electrical conductivity The thermal and electrical conductivity of CBI is about 2 times that of DRI. This higher conductivity of CBI improves the distribution of heat created in the steelmaking furnace and, as a result, accelerates the melting process of iron materials. This will mean reducing the melting time of the steelmaking process and improving the production capacity of the steelmaking unit. 5- Carbon adjustment The presence of carbon in steelmaking furnaces is necessary in order to provide carbon for the final steel product, prevent excessive losses of iron, and also regulate the physical and chemical conditions of the slag. Usually, induction furnaces require low-carbon iron materials, but in electric arc furnaces, high-carbon iron materials are more attractive. The unique feature of CBI product is the ability to adjust its carbon content in the range of 0.5 to 4% by weight and based on the needs of customers.

Search Products on EximNext — Source From Verified Global Suppliers

This is the EximNext product search page — one place to search across our entire B2B catalogue of wholesale and export-ready products. Type any product name, material, grade, or HS-style keyword into the search bar above and instantly browse matching listings from verified manufacturers, suppliers, exporters, and wholesalers in more than 200 countries. Whether you are sourcing raw materials, components, machinery, or finished goods, the search brings the right products and the right factories to one screen so you can compare and shortlist in minutes instead of days.

Search across hundreds of thousands of products and every major category

The catalogue spans the full breadth of international trade: agriculture and farm inputs, food and beverages, apparel and fashion accessories, electronics and electrical goods, industrial machinery and chemicals, construction and real-estate materials, minerals and metals, home furnishing, and a wide miscellaneous range. Each result links to a detailed product page with specifications, minimum order quantity, FOB and CIF pricing signals, certifications, and the supplier's trade profile. Because every category is interconnected, a single search can surface closely related product families — helping importers discover alternatives, substitutes, and adjacent lines they may not have considered.

Filter, compare, and shortlist the right suppliers

Use the side filters to refine results by supplier country, business type (manufacturer, exporter, trading company, distributor), verification status, certifications, price band, and minimum order quantity. Sort by relevance, price, or recency, and switch between list and grid views. Every supplier on EximNext is surfaced with the trust signals that matter for cross-border trade — verification, response rate, and trade history — so you can build a credible shortlist before you ever send an inquiry.
