What is the abbreviation for Basic Oxygen Steel-making? What does BOS stand for? BOS abbreviation stands for Basic Oxygen Steel-making.
Get PriceBasic Oxygen Furnace (BOF) is a steel making furnace, in which molten pig iron and steel scrap convert into steel due to oxidizing action of oxygen blown into the melt under a basic slag. Primary steelmaking Known as Linz-Donawitz-Verfahren steelmaking 28.4.2015 2 In 1856, Henry Bessemer patented a steelmaking process involving oxygen
Get PriceSteel is made by the Bessemer, Siemens Open Hearth, basic oxygen furnace, electric arc, electric high-frequency and crucible processes. In both the Acid Bessemer and Basic Bessemer (or Thomas) processes molten pig iron is refined by blowing air through it in an egg-shaped vessel, known as a converter, of 15-25 tonnes capacity.
Get PriceBasic oxygen steelmaking is a primary steelmaking process for converting molten pig iron into steel by blowing oxygen through a lance over the molten pig iron inside the converter. Exothermic heat is generated by the oxidation reactions during blowing. The basic oxygen steel-making process is .

Oxygen is one of the basic chemical elements. In its most common form, oxygen is a colorless gas found in air. It is one of the life-sustaining elements on Earth and is needed by all animals. Oxygen is also used in many industrial, commercial, medical, and scientific applications. It is used in blast furnaces to make steel, and is an important ...
Get PriceA basic oxygen furnace is a reactor in which oxygen is blown through molten pig iron that is heated to approximately 1,600℃ to convert it into steel. As the basic oxygen furnace shell is exposed to severe high-temperature conditions during use, its material experiences gradual degradation leading to thermal deformation and cracking that ...
Get PriceBasic oxygen steelmaking is a method of primary steelmaking in which carbon-rich molten pig iron is converted into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into steel. The process is known as basic due to the chemical nature of the refractories—calcium oxide and magnesium oxide—that line the vessel to withstand the high .
Get PriceThis is one of the three original 60-ton vessels by which the basic oxygen process (BOP) of steel making was introduced into this country from Austria, where it was invented. It heralded the first new technology in fifty years to become the basis of a major process for steel production throughout the world.
