In this paper, a new method of basic oxygen furnace (BOF) slag component modifiion with a regulator was studied. The main mineral was designed as C4AF, C2S and C3S in modified BOF slag, and the batching method, mineral compositions, hydration rate, activation index and capability of resisting sulfate corrode also were studied. XRD, BEI and EDS were used to .

· Basic Oxygen Furnace (BOF) steel slag aggregates from NW Spain were tested in batch and column experiments to evaluate its potential use as a substrate in constructed wetlands (CWs). The objectives of this study were to identify the main P removal mechanisms of BOF steel slag and determine its P removal capacity. Also, the results were used to discuss the suitability of this material as a ...
· 10 BASIC OXYGEN FURNACE (BOF) From the blast furnace, molten pig iron (hot metal) is poured into a torpedo car and subsequently into a ladle. The metal in the ladle is sent directly to the basic oxygen furnace (BOF) or to a pretreatment stage. A water cooled lance is lowered down into it. This lance blows 99% pure oxygen into the converter, igniting the carbon dissolved in the steel and ...

· Basic oxygen furnace slag (BOFS) is a byproduct of the steel manufacturing industry. The steel industry is amongst one of the largest waste producers. The global slag output from the steel industry was reported to be over 1600 million tons per annum .
· Slopping of Slag in Basic Oxygen Furnace. Steelmaking in basic oxygen furnace (BOF) is a batch process in which steel is made from liquid iron. The concentration of elements such as carbon (C), manganese (Mn), and phosphorous (P) have an impact on the steel quality. For the steel to be cast, it needs to be at a predefined temperature. To achieve the predefined temperature and composition ...
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 appliion in construction. Moreover, the iron content in BOF slag of 14–30wt% is a quantity which is problematic in the manufacture of cements. On the other hand, BOF slag is a source of available iron in the ...
Basic oxygen furnace (BOF) slag is a byproduct of steel plants and is different from conventional natural aggregates. Studies have shown that BOF slag asphalt concrete is able to store heat. However, no quantitative research results have been presented. In this study, conventional natural aggregates and reclaimed asphalt pavement (RAP) are replaced by BOF slag in an asphalt concrete mixture ...
Basic oxygen furnace (BOF) slag media were studied as a potential treatment material in onsite sanitation systems. Batch and column studies were conducted to evaluate attenuation of the bacteriophage PR772 and microm diameter microspheres by BOF media, and to delineate the relative contributions of two principle processes of virus attenuation: inactivation and attachment.

· basiciddecarbonization, chemistry, slag, Chemistry of Steelmaking by Basic Oxygen Furnace. During the steelmaking process by basic oxygen furnace (BOF), impurities in hot metal such as carbon (C), Silicon (Si), manganese (Mn), phosphorus (P) etc. are removed by oxidation for the production of liquid steel. Oxidation is carried out with high ...
· 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 monooxide), CO2 (carbon dioxide), .
