Steel slag, which is a by-product of steel industry, mainly refers to basic oxygen furnace slag (BOF-slag) and electric arc furnace slag (EAF-slag). BOF-slag originates from the further refining of iron in a basic oxygen furnace while EAF-slag is derived from melting recycled scrap in an electric arc furnace ( Barca et al., 2013 ).
BOF Slag Detection Systems Basic Oxygen Furnaces (BOF) slag is the main problem at all iron and steel making factories. Steel slag is a solid waste from steel production. Monocon can provide a range of slag detection cameras as part of the complete slag control package.
Slags from steel convertor operations are characterized by a high lime content, of which a significant percentage of "free" lime. This complicates its valorization.

N2 - In this study, the early age hydration kinetics of BOF slag is investigated. Isothermal calorimetry and in-situ X-ray diffraction (XRD) are used to examine the effects of K3-citrate concentration and nanosilica addition on slag reactivity. The results reveal that brownmillerite is the most reactive slag phase during the first 24 h of hydration. The kinetics of brownmillerite hydration is ...

Basic oxygen furnace (BOF) steel slag is a main byproduct in steelmaking, and its valorization is therefore of considerable interest, from a metal-recovery perspective and from a residue-utilization perspective. In the present study, the carbothermic reduction of BOF slag was investigated systematically. The reductions of Fe- and P-containing phases (i.e., oxide and compounds) are discussed ...
Mar 10, 2021The mining industry generates large quantities of waste as tailings. The tailings have an adverse environmental impact. This study explored the utilization and stabilization of Barberton gold mine tailings (GMTs) and basic oxygen furnace slag (BOFS) to synthesize geopolymers for other applications. The geochemical, chemical, and geotechnical properties of GMT, BOFS, GMT geopolymer, and GMT ...

Slag composition also determines the physical properties of molten oxide mixtures, which is similarly important in the steelmaking process. For example, slag viscosity is im-portant in BOF steelmaking and blast furnace ironmaking in terms of slag fluidity.5-7) In addition, the chemical com-position of molten oxide mixtures affects the life ...

ing of Slag in Basic Oxygen Furnace. In basic oxygen furnace (BOF) steelmaking, a supersonic oxygen (O2) stream is injected onto the surface of the hot metal bath. The impurity elements in the bath such as carbon (C), silicon (Si), manganese (Mn), and phosphorus (P) are oxidized and removed from the bath in the form of CO (carbon mono-oxide ...
This slag is known as steel making slag or BOF/LD slag and is considered as a solid waste by the steel industries. About 150-200 kg of BOF slag is generated per ton of liquid steel...

Both basic oxygen furnace (BOF) slag and cold-rolling wastewater (CRW) exhibiting highly alkaline characteristics require stabilization and neutralization prior to utilization and/or final disposal. Using CO2 from flue gases as the stabilizing and neutralizing agents could also diminish CO2 emissions. In this investigation, ex situ hot stove ...

ABSTRACT Basic Oxygen Furnace (BOF) slag is one of the sub-products generated in the steelmaking process. This waste is characterized by its free lime and free magnesia contents that limit its application in construction. Moreover, the iron content in BOF slag of 14-30wt% is a quantity which is problematic in the manufacture of cements.

The pretreated hot metal was refined in BOF operation with zero addition of slag-forming materials. The total slag amount in steelmaking sector could be reduced from 130 kg/ton (steel) with the conventional operation to a level of 60 kg/ton (steel) in the new system. BOF slag itself was reduced to 10 kg/ton (steel).
The Basic Oxygen Steelmaking process differs from the EAF in that it is autogenous, or self-sufficient in energy. The primary raw materials for the BOP are 70-80% liquid hot metal from the blast furnace and the balance is steel scrap. These are charged into the Basic Oxygen Furnace (BOF) vessel. Oxygen (>99.5% pure) is "blown" into the BOF ...
