Cold Briquetted Iron (CBI) is defined as DRI which has been molded at a temperature less than 650 �°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.
Linear Alkylbenzene (LAB) is a cost-effective and biodegradable intermediate in the production of detergents and surfactants.
Linear Alkylbenzene Sulfonic Acid (LABSA) is an anionic surfactant that was primarily introduced in 1964. It has been the world's largest-volume synthetic surfactant since then. LABSA is widely used in household detergents as well as in numerous industrial applications
Normal Paraffin (NP) is a clear liquid that are made up of saturated hydrocarbons with a straight-chain structure. They are either extracted from kerosene or through the Fischer-Tropsch process at gas-to-liquid production sites. Paraffin (or called kerosene) is a mixture of hydrocarbons; it usually consists of about 10 different hydrocarbons, each containing from 10 to 16 carbon atoms per molecule; the constituents include n-dodecane, alkyl benzene, and naphthalene and its derivatives. Kerosene is obtained from crude oil by distillation and is used as a fuel for heating and aircraft. N-paraffin C10-C13 is a colorless liquid with a mild odor. It is insoluble in water. It is slow-evaporating, environmentally adapted (fully bio-degradable) with negligible sooting (like lamp oil).
Normal Paraffin is the major raw material for the manufacture of the LAB. Normal Paraffin is extracted from kerosene which contains an average of 20/25% paraffin and therefore is generally produced close to a refinery as the kerosene, free of the paraffin removed has to be returned to the refinery. Over 80% of Normal Paraffin is used for the production of the LAB the remaining N-Paraffin may be further processed to obtain special solvents used for various industrial applications including synthetic resins, paints and varnishes, degreasing agents and printing inks. Normal paraffin operates as a dissolver in industrial for producing polymers and resins, colors, artistic coverings and grease polisher.
Slack wax is the by-product of the base oil refinery process which is a mixture of oil and wax. Slack wax is fed into the system as raw material which is finally processed into different grades of paraffin wax after performing the refining processes, de-oiling and bleaching.
Foundry Pig Iron is suitable for iron castings used in general engineering, machine
tools and parts for the automotive industry. Due to the high proportion of iron ore
used in the production of Foundry Pig Iron, the formation of pearlite in the finished
casting is promoted. This effect is enhanced when more than 10% of Pig Iron per
charge is used.
The use of Foundry Pig Iron promotes graphite formation, reduces primary chill and
improves machinability, particularly important in thin-walled castings The use of costly chill reducing inoculants can be minimised through increased addi-
tions of Foundry Pig Iron.
The high density and high carbon content of Foundry Pig Iron improves melting rates
or reduces energy consumption. In an electric induction furnace savings can be as
high as 50 kWh/t of molten metal. In a cupola furnace savings of up to 50 kg coke/t
of molten metal can be achieved.
The higher bulk density of pig iron relative to scrap means lower storage space re-
quirements, less handling during charge make-up, fewer charge buckets and lower
charging time.
â?¢ The lower surface area : volume ratio relative to scrap means lower oxide (rust) for-
mation and thus lower slag volume.
The carbon content is chemically combined and thus goes into solution more quickly
with lower energy requirement than when adding a recarburiser to scrap
