In stainless steel production, slag from argon oxygen decarburization (AOD) converters is dumped on to the ground and then slowly cooled. The slag undergoes phase transformation from β-dicalcium silicate (β-C 2 S) to γ-dicalcium silicate (γ-C 2 S) at approximately 500 °C to 450 °C, resulting in slag volume expansion, disintegration, and dust generation.
(A relatively small amount of chromite ore is used to add directly to stainless steel melts.) The addition of chromium to iron alloys enhances their resistance to corrosion, oxidation, wear, and impact. Another important, although small, metallurgical use of chromite is in the production of chromium alloys with nickel.
Advantages of Calcium Silicate Bricks. There are many advantages of calcium silicate bricks when used in masonry construction, and they are: Mortar required for providing plaster on calcium silicate bricks is very less. Color and texture of these bricks is uniform. Compressive strength of sand lime bricks is about 10N/mm 2.
Stainless steel is known for excellent corrosion resistance. It is an integral part of modern life and is used in a range of applications, including heavy industry, architecture, automotive manufacture, surgery and dentistry..

Limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. Basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material. The process of iron making is …
Cast iron is produced in a 'cupola furnace,' historically built from brick although modern ones tend to be steel with a refractory lining. Charges of iron ore and charcoal (or coke) are fed into the top of the stack and molten metal accumulates in a well a the the bottom where it can be 'tapped' by punching through a clay plug.
Oxygen lancing is often used for removing carbon in the presence of chromium and enables scrap stainless steel to be used. The nitrogen content of steels made by the Bessemer and electric arc processes is about 0,01-0,25% compared with about 0,002-0,008% in open hearth steels.
The argon oxygen decarburization (AOD) process is used to make stainless steel and specialty grades of steel, including tool steels, silicon steels, low-alloy steels, and low-carbon steels. In this process the tuyeres are submerged, resulting in high element recovery, rapid and efficient desulfurization, and good control of the slag chemistry.

12.4 Ferroalloy Production 12.4.1 General Ferroalloy is an alloy of iron with some element other than carbon. Ferroalloy is used to physically introduce or "carry" that element into molten metal, usually during steel manufacture. In practice, the term ferroalloy is used to include any alloys that introduce reactive elements or alloy
Calcium silicate does not cope well with water. To avoid water invasion, it is essential that the silicate is covered with a protective coat. This could be a traditional aluminium or stainless-steel sheet, PVC, a glass-based climate barrier or some other laminate. Sealer is used to make sure that any type of overlaps are watertight as well.
