Recycling of steel plant mill scale via iron ore sintering ...

The mill scale contains high amounts of Fe and low amounts of silica and alumina. Thus, recycling it through the sintering process helps in the saving of raw materials like iron ore and limestone. This paper presents preliminary findings of a study that investigates the potential for recycling steel mill scale in the sintering process. Experiments were conducted using the mill scale in sinter making from 0 to 70 kg/t

Recycling of steel plant mill scale via iron ore ...

2013-11-29  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.

Preparation and Characterization of Mill Scale

2019-8-30  However, a study on recycling mill scale of steel in the sintering process showed that the sinter productivity decreased with the increase in mill scale addition due to decreased permeability of the sinter bed. In recent years, steelmakers used this mill scale as an oxidizer in a conventional electric arc furnace steelmaking process [ 5 ].

What exactly is Mill Scale and what is done about it

Mill scale is porous and poorly adherent scale of magnetite, it will only give limited short term protection to steel against corrosion. If you are coating any steel surface against corrosion it is necessary to blast clean (with garnet or similar) to a finish of Sa2.5 blast standard before coating.
