Basic slag is a coproduct of steelmaking, and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route. To flux the silica produced during steelmaking, limestone and/or dolomite are added, as well as other types of slag conditioners such as calcium aluminate or fluorspar .
stitution of Basic oxygen furnace slag enhances the Flexural strength of M25 concrete mix up to certain percentage. After adding 15% Basic Oxygen furnace slag in the mix, there is an increase of % strength after 7 days, and % increase after 28 days. The Flexural strength increases as compared to control mix as the percentage of Basic Oxy
Basic oxygen furnace slag. Basic oxygen furnace slag BOS (also called LDconverter slag)is formed during the conversion of hot metal from the blast furnace into steel in a basic oxygen furnace. In this process the hot metal is treated by blowing oxygen to remove carbon and other elements that have a high affinity to oxygen. The slag is generated by the addition of fluxes, such as lime [stone] and/or dolomite
A steelmaking slag (basic oxygen furnace) obtained from the Kardemir Steelworks was modified to be used as a clinker additive in the cement industry. This study confirmed that the compressive stre...
Abstract: Basic oxygen furnace slag (BOFS) was ground to three levels of neness as a replacement for cement at weight proportions of 10, 30, 50, and 70 wt.%. Fineness and weight proportion were shown to have signicant effects on the owability and setting time of the mortars. The expansion of
The lumpmakingswelteringdisintegrating method is applied to manufacture asphalt concrete graded aggregates. Basic oxygen furnace slag at 1200 is poured into a shallow slag pot for initial cooling. The slag with reduced surface temperature is transported to a puddle, and then sweltered in a stockpile, which will make it disintegrate into aggregates naturally so that flattened graded aggregates can be
Basic Oxygen Furnace. Basic oxygen furnaces are equipped with air pollution control systems for containing cooling and cleaning the volumes of hot gases and submicron fumes released during the process. so a more realistic limit for charcoal usage may be around 50 of the total solid sintering fuel. Slag use as an aggregate in concrete
Abstract. Steel slags are industrial byproducts of steel manufacturing, characterized as highly calcareous, siliceous and ferrous. They can be categorized into basic oxygen furnace (BOF) slag, electric arc furnace (EAF) slag, and ladle furnace (LF) slag. They are found to be useful in many fields, such as road construction, asphalt concrete, agricultural fertilizer, and soil improvement.
Basic Oxygen Furnace an overview | ScienceDirect Topics
The molten slag is cooled and solidified into basic oxygen furnace slag, which then undergoes crushing, magnetic separation, and screening to make BOFS graded aggregates. Their physicochemical properties are listed as follows: Composition (%) SiO 2. Al 2 O 3. CaO.
