Jul 18, 2013· Traditionally, iron ore has been reduced with coke in a blast furnace and the hot metal product of the blast furnace containing carbon, manganese, silicon, sulphur and phosphorous, was subsequently refined in a steelmaking furnace. During ironmaking as well as during steelmaking, significant amounts of slag are produced.
Steel slag is a residue produced by refining iron to steel in openhearth, basic oxygen and electric arc furnaces. ... recycling slag by means of the sinter plant has declined because of .
The main reasons why steel slag may be considered to be difficult to grind may be due to the incorporation of iron scrap. In the laboratory experiments reported here, about 22% by weight of steel slag was attracted by the reseparation magnet, the separated slag particles consisting mainly of fine iron particles.
Jul 01, 2019· Slag is a mainly nonmetallic byproduct that is made up of silicates, alumina silicates, calcium aluminum silicates, and iron oxides (Joulazadeh and Joulazadeh, 2010). During the BOS process a proportion of the molten iron cannot be recovered so elemental iron is often observed in the slag (Yildirim and Prezzi, 2011). Slags can be classified ...

A slag disposal method for disposing of slags produced in furnaces during iron or steel making processes comprises employing the steps of magnetic sorting of masses of crude slags of a size greater than a value ranging between 300 to 500 mm obtained from the furnaces into slags rich in iron (above about 50 to 60 percent) and slags not rich in iron (below about 50 to 60 percent) .
Slag is the glasslike byproduct left over after a desired metal has been separated (, smelted) from its raw is usually a mixture of metal oxides and silicon, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature .
Slag cement, originally known as granulated blastfurnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag.

Both types of slag are reused as a raw material for cement or as a bedding material in road construction. Compared with regular ...
Among them, 50% of steel slag has been used for the road project directly, with the remaining part for sintering and ironmaking recycling in the plant. The resource application technology of steel slag is usually based on the research and development of steel slag .
Iron Steel Slag Recycling Machine. Slag is a partially vitreous byproduct of the process of smelting ore to separate the metal fraction from the unwanted fraction. Slag is usually a mixture of metal oxides and silicon dioxide. With the development of technology, recycling the iron steel slag has aroused the attention from scientists and ...
Since the beginning of the industrial age, slag, the glassy material left over when metals are refined from ore, has been considered ugly but harmless. ... not ease of disposal .
Jun 06, 2016· One constraint to the recycling of slag to recover the metals is that fine materials may have to be pelletized or briquetted prior to recycling. Reuse The resulting clean slag with low metal content in the above example is either granulated to produce abrasives or cooled slowly and broken into lumps for filling or construction material.
