Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. ...

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, iron oxides consisting of Iron(+II,III) oxide, hematite, and magnetite. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.

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.

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. The raw materials are sometimes mixed with water to provide a cohesive

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.

A byproduct of the steel manufacturing industry, mill scale has many industrial uses as a raw material. It consists of oxides of iron that form on the surface of hot metal during processing. While the steel is very hot, it picks up oxygen from the air and forms a thin crust. As the steel is stretched and shaped, the thin crust falls to the ground.

Overall, steel production is the largest iron ore application. The basic raw materials of large-scale steelmaking are: The basic raw materials used in the large-scale steelmaking process are: • iron ore, treated in some way after it comes from the mine • coal, which must be converted to coke • limestone

Our robust pug mills (paddle mixers) and rotary dryers are also frequently relied upon for processing steel by-products in the form of dust and scale in order to liberate iron ore. Rotary dryers may also be used in ore drying applications. We can also supply briquetters for briquetting sponge iron and hot briquetted iron (HBI).

According to the U.S. Environmental Protection Agency, 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 can be used in other iron ore preparation for steel making but it may require crushing and grinding it to very specific sizes and too expensive or it can be briquetted and used directly. If it is used directly the further preparation and processes to use it would have to be scrutinized to ensure that it would be efficient and ...

The function of an iron sintering plant is to process fine-grained materials, e.g iron ore fines, iron concentrates or secondary iron oxide wastes like millscale or collected dust, into coarse-grained iron ore sinter for use in charging the blast furnace. The sintering process is a pre-treatment phase in the production of iron.

Mill scale is an iron oxide waste generated during steelmaking, casting and rolling. Total generation of mill scale at JSWSL is around 150 t/day and contains 60–70%FeO and 30–35%Fe 2 O 3.To recover the iron, the mill scale must be smelted in a blast furnace or other reduction furnace; however, it is usually too fine to use without previous agglomeration such as via pellet or sinter mix.

MILL SCALE: Is a by product of iron and steel industries. It is formed when iron is rolled or by steel billets in rolling mills. We have good grade of mill scale as per your requirements.

Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies.
