The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a #4 sieve. The efficiency, which the molten blast furnace slag is rapidly chilled, as well as the chemical composition of the slag source, largely determines its cementitious properties for use in concrete.
Blast furnace slag materials are generally available from slag processors located near iron production centers. Cements containing ground granulated blast furnace slag are available from many producers of Portland cement or directly from ground granulated blast furnace slag cement manufacturers.
Slag formers are either charged with the scrap or blown into the furnace. The Si and Al in the scrap are oxidized first to form SiO 2 and Al 2O 3 (fluxing oxides). As oxygen is blown into the furnace, the principal flux (FeO) is generated. The "slag balance" now starts to shift and the slag …
Aug 07, 2015· Slag and its Role in Blast Furnace Ironmaking Blast furnace (BF) is the oldest (more than 700 years old) of the various reactors which are being used in the steel plants. It is used for the production of liquid iron (hot metal).
A ground granulated blast furnace slag for sulfate resistant cement comprising a mixture of ground granulated blast furnace slag with an alumina content of 12 to 17.5 mass % and high dissolution rate gypsum of 2 to 6 mass % of gypsum converted to mass of SO 3 .
The amounts of dissolved Si, Ca, and Mg increased with decreasing solution pH. The solubility of the convertor slag was highest amount the tested slags in terms of the percentage of dissolved Si to total Si in the slag when solution pH was from 5 to 7, but was lower than those of blast furnace slags at pH 4.

US Patent for Roll press grinding aid for granulated blast . A grinding aid and an enhanced roll press method of grinding granulated blast-furnace slag by treating the slag feed of the roll press with from about 0.002 to 0.2 weight percent of polyacrylic acid or its alkali metal salt in combination with up to about 4 weight percent water.
The effect of microwave-supported leaching of electric arc furnace (EAF) slag by ammonium salts was investigated to improve calcium leaching ratio for CO2 mineral sequestration process. The results show that the calcium leaching ratio from EAF slag at the constant temperature in the microwave field increases about 10% than that under the water bath at the same leaching time.

immobilization method using blast furnace slag is a method of immobilizing it as calcium carbonate by the reaction of calcium oxide in the slag and CO 2 on the surface of slag particles. Therefore, it is important to promote the reaction between CO 2 gas and calcium content in the slag…
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Substantial amounts of magnesium, silicon, aluminium, and iron originating from the blast furnace slag also ended up in the calcium carbonate precipitate. The calcium acetate solution should therefore be free of these elements, in order to produce calcium carbonate suitable for use as PCC (i.e. 99% purity) from blast furnace slag.

Solid solution of iron (ll)-oxide with MgO and MnO ... Gehlenite, calcium-aluminum-silicate [Ca2Al2SiC>7] Bredigite, calcium-magnesium-silicate 4. FIRST AID MEASURES EYES: If ...
As the extraction ratio of calcium in EAF slag is nearly 70% and reaction ratio of calcium in leaching solution with carbon dioxide almost reaches, CO 2 uptakes can be calculated as 306 g CO 2 /kg slag for the EAF slag containing 39% calcium oxide, compared to the thin-film condition and slurry-phase route (176~280 g CO 2 /kg slag) .
Basic slag is a co-product 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 .

Oct 01, 2018· Large quantities of CO 2 and blast furnace (BF) slag are discharged in the iron and steel industry. Mineral carbonation of blast furnace slag can offer substantial CO 2 emission reduction and comprehensive utilization of the solid waste. An energy- and cost-efficient mineral carbonation technology combined with NH 3 capturing CO 2 and simultaneous power generation is presented in this article.
Slag plays a very important role in steelmaking to the extent that it is said that "make a slag and slag makes steel". Slag is a generic name and in steelmaking it is mostly a solution of oxides and sulphides in the molten state and t he multi -crystalline phases in the solid state. Slag is a separate phase because

Calcium carbide is converted into acetylene in a controlled reaction with water using an apparatus called a generator. Acetylene, which has the chemical formula C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between the carbon atoms.
