Basic Oxygen Furnace (BOF) slag is one of the subproducts generated in the steelmaking process. This waste is characterized by its free lime and free magnesia contents that limit its application ...
Get PriceThe basic oxygen furnace (BOF), whose profile is shown in the figure, is a tiltable vessel lined with refractories such as magnesia carbon brick. Auxiliary equipment includes a chute for scrap charging, hoppers for alloys and fluxes, a lance for injecting pure oxygen gas, a sublance for measuring the temperature and carbon concentration of the ...
Get PriceBasic oxygen steelmaking is a primary steelmaking process for converting the 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.
Get PriceRecycling and Reuse of Basic Oxygen Furnace (BOF)/Basic Oxygen Process (BOP) in Steelmaking Slags (Continued) Based on previous research conducted by MTU, it is believed that steelmaking slag can be processed into highiron and noniron fractions.
Get PriceJNE Automation, in conjunction with NuPro Corporation, has integrated automated basic oxygen furnace (BOF) tapping systems on four Basic Oxygen Furnaces in North America. Our partnership provides a complete solution, including a vision system to monitor the slag level in the vessel during tapping to control the rate of tapping to minimize slag ...
Get PriceBasic oxygen furnace (BOF) slag has increased skid resistance and high level of strength (described by the impact and crushing value) compared to natural rocks ( basalt) and thus makes it an ideal aggregate for road constructions and surface layers for high skid resistance.
Get PriceThe work environment around an open hearth furnace is said to be extremely dangerous, although that may be even more true of the environment around a basic oxygen or electric arc furnace. Basic oxygen steelmaking eventually replaced the open hearth furnace. It rapidly superseded both the Bessemer process and Siemens–Martin process in Western Europe by the 1950s and in Eastern Europe by the .
Get Priceliquid steel by blowing oxygen into the molten iron (Basic Oxygen Steelmaking). Along with the liquid iron that was produced in the blast furnace, recycled scrap steel is also added to the oxygen furnace. Pure oxygen is then blasted into the furnace at supersonic speeds via an oxygen lance that is lowered from the top. An oxygen lance is a ...
Get PriceMeet the Instructors. Among these five elements, silicon is most attractive element to oxygen, so when oxygen blowing is start silicon is the first element to oxidize. Silicon concentration quickly decreases, then it becomes silicon oxide formed slag with added lime .
Get PriceOct 31, 2014· Effectiveness of basic oxygen furnace slag (BOFS) for removing dissolved phosphorus (P) was evaluated in a hypolimnetic withdrawal system. Lake water collected from the hypolimnion, with phosphate (PO 4P) concentrations of to mg/L, was passed through a pilotscale (pore volume, ∼ m 3) treatment system over two successive summers.
Get PriceBasic oxygen furnace (BOF) slag, a byproduct of steelmaking processes, is mainly composed of calcium compounds and thus has high potential for carbonation. The purpose of this study was to use an ...
Get Priceproject fact sheet recycling and reuse of basic oxygen furnace (bof)/basic oxygen process (bop) steelmaking slags new technologies and methodologies may allow value added utilization of steelmaking slag thus reducing waste and use of landfills, and saving energy office of industrial technologies energy efficiency and renewable energy • department of energy
Get PriceDec 12, 2015· In this paper, the results of a series of tests (grainsize analysis, Xray diffraction, specific gravity, compaction, maximum and minimum dry unit weight, direct shear, consolidateddrained triaxial compression, and longterm swelling tests) performed on samples of both fresh and aged basic oxygen furnace (BOF) steel slag from a steel plant in Indiana are presented and analyzed.
