Basic oxygen steelmaking is a method of primary steelmaking in which carbon-rich molten pig iron (the iron created in the blast furnace) is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.
4 2.1.2 Pickup of Other Elements When adding scrap it is also important to be aware of, and if necessary calculate, the effect of elements other than iron on the overall steel composition. The new content of a given element is calculated by Equation 9-3: where %X!= content of element i in wt-%

basic oxygen furnace and electric arc furnace 12. The iron tapped from the blast furnace is which one of the following: (a) cast iron, (b) low alloy steel, (c) low carbon steel, (d) pig iron, (e) pure iron, or (f) stainless steel? pig iron 13.
Blast furnace sludge (BFS) is a waste with elevated mercury (Hg) content due to enrichment during the production process of pig iron. To investigate the volatilization potential of Hg, fresh samples of BFS mixed with basic oxygen furnace sludge (BOFS; a residue of gas purifiion from steel making, processed simultaneously in the cleaning devices of BFS and hence mixed with BFS) were studied
The oxygen top blown converter (Basic Oxygen Furnaces) is blown by industrial pure oxygen furnace. The lining of the furnace is mostly alkaline, like a straight bucket. The oxygen is injected into the surface of metal liquid by the water-cooled nozzle at the top of the furnace at a high speed of Mach 3/h.
In the process of BOF(basic oxygen furnace) steelmaking, in order to figure out and optimize the amount of alloy addition during deoxidizing and alloying of tapping, optimization model of this process is very indispensable. For this reason, multi-objective
Basic-oxygen furnace slag (BOF-slag) contains >35% CaO, a potential component for CO2 sequestration. In this study, slag-water-CO2 reaction experiments were conducted with the longest reaction duration extending to 96hr under high CO2 pressures of 100-300kg/cm(2) to optimize BOF-slag carbonation conditions, to address carbonation mechanisms, and to evaluate the extents of V and Cr …

----- basic oxygen process furnace is also known as the oxygen blown steel-making process. (It should be noted that oxygen may also be used in the open hearth process to increase production ratas.) High purity oxygen (95% or better) is blown into the molten metal bath in the vessel.
Steel 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.
