Iron and steelmaking slags (ferrous slags) are co-products of the iron and steel making industry. They are non-metallic rock-like materials which are produced together with the metallic products of these processes. Depending on the iron and steel production process different slag types can be manufactured. Blast furnace slag is made during the melting and reduction of iron []
The calcined limestone combines with impurities to form slag, primarily calcium silicate, which floats on top of the molten iron and can be removed: (5.8) CaO + SiO 2 → CaSiO 3 In the second stage of the steelmaking process, known as basic oxygen steelmaking (BOS), the carbon content of pig iron is reduced from a typical 4–5% to 0.1–1% in
Description. Cast Iron Slag Pot. Slag Pot Iron Casting is a load-bearing device whose sole purpose is to collect molten or solid slag generated during metallurgical or chemical processes, to retain it during transport and to deposit it at a place of disposal.

(PDF) IRON AND STEELMAKING SLAGS: ARE THEY HAZARDOUS
The specific charge of metal stock when melting with slag removal as shown in Table 1 is more by 4.3 kg/t of steel and related to higher slag oxidation (by 1.44 %) and additional iron loss with
Metal Profile: Iron Properties and Characteristics
Jan 12, 2020Slag is lighter than molten iron ore, so it rises to the surface and can easily be removed. The hot iron is then poured into molds to produce pig iron or directly prepared for steel production. Pig iron still contains between 3.5% and 4.5% carbon, along with other impurities, and it's brittle and difficult to work
Effects of Temperature, Oxygen Partial Pressure, and
Slag penetrations are shallower in oxidizing conditions than they are in reducing conditions because the iron-oxide from the slag solutions into the corundum-structured refractory and the slag is depleted of iron-oxide, increasing the viscosity of slags.
Iron Ore Sintering: Process: Mineral Processing and
Feb 16, 2017Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
Control of Slag and Insoluble Buildup in Ladles, Melting

What is an Iron Slag Abrasive? Definition from
Jan 14, 2018An iron slag abrasive is a type of abrasive grit material that is collected from iron ore after it is smelted and refined in a furnace. Iron slag is considered a general purpose abrasive. Iron slag abrasive is also known as calcium silicate, which is the name of the chemical compound that it is made from.

Choosing the Right Blast Media for Abrasive Blasting
Coal slag is by-product of coal-burning power plants, considered a “green” abrasive because it would otherwise be disposed of as waste. It is a relatively cheap, low dusting abrasive with low free silica, but is considered a dirty abrasive and not widely used in wet abrasive blasting because the high amount of “fines” (fine particles

Frequently Asked Questions What is Coal Slag? US Minerals
What is coal slag? This stuff is boiler slag, which is a recycled product from coal burning plants. When coal is “fired” at over 2500 degrees it melts and produces a by-product called slag. When the slag is cooled through a process called vitrification, it crystallizes, forming sharp, angular granules in a variety of sizes.
Slag/metal reactions are very important in the production of clean metals (eg. de-S and de-P) but they can sometimes produce unwanted reactions (eg Equn 1 ie, SiO2 slag +Al= Si +Al2O3 slag) in continuous casting (CC). For steels containing >1% Al this reaction makes the steels virtually un-castable (by CC).

Copper processing Roasting, smelting, and converting
Iron and sulfur are converted to oxides and are removed in either the gas stream or the slag (the latter being recycled for the recovery of remaining values), leaving a “ blister” copper containing between 98.5 and 99.5 percent copper and up to 0.8 percent oxygen. The converter is rotated for skimming the slag and pouring the blister copper.
