In the steel industry, using high-quality raw materials plays an important role in optimizing the production process. One of these materials is cold briquetted sponge iron, which, with its unique characteristics, has gained a special place in steelmaking plants. This article provides a comprehensive introduction to cold briquettes, their production methods, advantages, and applications
Cold Briquetted Iron (CBI) is a type of compressed material produced by compressing sponge iron at ambient temperature. This type of briquetting, which is part of the cold briquetting process, is done without the application of heat, resulting in a product with high density, adequate strength, and remarkable metallic purity
:Cold briquette production is carried out through the direct reduction process of sponge iron. The process involves
First, the reduced sponge iron is produced
This material is then mixed with some water and a special binder
The final mixture is compressed under high pressure in a briquetting machine
The end result is a cold briquette with high physical and chemical resistance
High resistance to fragmentation and wear
High chemical stability and minimal metallic grade loss
High density (over 4.5 grams per cubic centimeter)
High metallic grade (over 96%)
No need for pelletizing before use
Ability to recycle metallic waste, including pellet fines
:Cold briquettes play a key role in optimizing melting and steel production processes. Some of the main applications include
A suitable alternative to scrap in electric arc and induction furnaces
Used in blast furnaces to reduce coke consumption and increase efficiency
Suitable for producing alloy steels with minimal impurities
Used as a coolant in steelmaking converters
Given the rising cost of raw materials and the need for high-quality steel production, using cold briquetted sponge iron can be an economical and technical choice for steel plants. This material, in addition to reducing production costs, significantly improves the final steel quality
Cold briquettes, with features such as high density, adequate physical resistance, and high metallic purity, are a very suitable option for replacing scrap in steelmaking industries.
