SINTERING shall mean those operations conducted by the heating of iron bearing wastes (mill scale and dust from blast furnaces and steeling making furnaces) together with fine iron ore, limestone, and coke fines in an ignition furnace to produce an agglomerate for charging to the blast furnace.
The sintering converts fine-sized raw material, iron ore, coke breeze, limestone, mill scale, and flue dust into an agglomerated product (sinter) at suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a cohesive matrix and then placed on a travelling grate called the sinter strand. A burner
Mill Scale is not a common commodity to carriers and while is may not be covered by any steel industry code of practice it is covered by the marine industry IMSBC Code requirements. It should however be no surprise that as a commodity much likened to iron ore fines it is liable to liquefaction.
Whether referring to naturally iron-rich DSO fines or lump or artificially enriched beneficiated concentrate, one of the key elements that determines value is its chemical composition, or 'grade'. As a rule of thumb, a higher iron content will generally mean a higher market value for the ore since iron units are what a steel mill wants.
The sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.

Mill scale is a valuable ferrous raw material, containing 65 to 70 pct iron and is often recycled through the sintering process. During iron ore sintering, iron ore fines are mixed with limestone and coke breeze. The combustion of coke breeze supplies the necessary heat to achieve partial melting and reaction of the raw materials.
Direct reduced iron is iron ore in the form of lumps, fines or pellets that have had the oxygen removed by using hydrogen and carbon monoxide. Typical sources of carbon monoxide are natural gas, coal gas, and coal. Other energy inputs into the production process often include oil and electricity. Since much of the energy used is in the form of ...
Sinter is the primary feed material for making iron and steel in a blast furnace.

Iron ore slime is generated from mines during processing and washing of iron ore, and it is not considered for pelletizing due to its excessive fineness and high gangue content, despite its good green bonding property. Mill scale is generated from steel rolling mills and reheating furnaces; it has almost nil gangue content, but is not individually considered for pelletizing due to its poor ...

Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product ...
We are beneficiating Iron Ore fines bearing Fe 56% to 300-325 mesh and then using a series of hydro-cyclones to bring the Fe up to 64%. I would like to explore the use of mill scale in crushed form (325 mesh/44 microns) for: 1. upgrading by green ball Fe content & 2. increase the quality of finished pellets in terms of reduction.

But, the mill scale can be reduced by suitable reductant to produce DRI (Direct reduced iron) or metallized iron ore. During the direct reduction process mill scale or iron ore has been reduced in a solid-state at a high temperature below the melting point (T < 1300 °C) in the presence of suitable reductants (solid or gaseous) to give metallized iron ore or DRI.

Mill scale is very attractive industrial waste due to its richness in iron (about = 72% Fe). In this paper, the characterizations of mill scale were studied by different methods of analyses. The produced mill scale briquettes were reduced with hydrogen at varying temperatures, and the reduction kinetics was determined. Two models were applied and the energy of activation was calculated.
Characteristics. As mill scale is a quite uncommon cargo, knowledge of its qualities is scarce. However, for practical purposes, the cargo can be compared with iron ore fines. It possesses a Transportable Moisture Limit (TML) and is liable to liquefy and/or form a wet base unless appropriate measures are taken.

Mill scale from rolling mills are collected. It is screened to seperate fastener or any other steel pieces present in the mill scale. The screened tailings are ground in pulverizer to fines.
Mill scale is traded effectively in the same way as primary mined iron ore fines since the physical nature of mill scale is similar to primary mined iron fines. However, it is to be noted that the mill scale is not a proper ?bulk cargo shipping name? (BCSN) under the IMSBC (International Maritime Solid Bulk Cargoes) Code.
