Steelmaking
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. ironmaking with iron sand under dynamic states in a low height furnace. As results, in the iron-sand refin-ing using a low-height furnace, the subjects of unit operations in the Methodology of Steel-making and Iron-making in Low Height

Manufacturers generally classify Sand materials into several main categories: Chromite, Silica, and Zircon. Chromite is an iron chromium oxide mineral that belongs to the spinel group.It is the most industrially Chromite Sand Manufacturing Process. Chromite ore is predominantly used in ferrochrome production an alloy of chrome and iron containing between 50% and 70% chromium. Steel production is the largest ferrochrome consumer, especially stainless steel production, which contains 10% and 20% ferrochrome content.

Steps in the Modern Steelmaking Process ThoughtCo
The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%. The EAF method, however, feeds recycled steel scrap through high-power electric arcs (with temperatures of up to 1,650 degrees Celsius) to The cast-iron is manufactured by re-melting pig-iron with coke and limestone. This re-melting is done in a furnace known as the cupola furnace. It is more or less same as the blast furnace, but it is smaller in size. Its shape is cylindrical with diameter of about 1 m and height of about 5 m. Fig. 10-2 shows a typical cupola furnace.Cast-Iron: Manufacture, Composition, Types, Properties and
