wet blast furnace slag
What is a Blast Furnace? Definition from CorrosionpediaThe main purpose of a blast furnace is to convert the iron ores, mined in the form of hematite or magnetite, to pig iron. The blast furnace is in use after the iron ores have been converted into ironrich pellets, and the coke and limestone prepared in the considerable amounts.Evaluation of a Warm Mix Asphalt Manufactured with ACBFS, AirCooled Blast Furnace Slag) and those that do in a faster way applying cold water jets (called expanded slag). The former are mainly used in construction as coarse aggregate (concrete and filling materials, among others), while the latter are more used in cement production (Rondón et al., 2018, 2018a). There are other types of slag
Effect of slag chemistry on the hydration of alkali Granulated blast furnace slag, a byproduct of the raw iron production, is almost exclusively used as a main ingredient of standard cements in Germany so far. A key aspect of slag research is therefore the identifiion of assessment criteria for the reactivity of ground granulated blast furnace slag (GGBFS).As evidence of the RTA's commitment to the increased As evidence of the RTA's commitment to the increased use of recycled materials, in June 1993 the RTA in This Guide to the Use of Iron Blast Furnace Slag in Cement and Concrete produced by the Australasian Slag WET STRENGTH In AS 2758.1(I), one of three methods of
Tapping Hot Slag for Energy Primetals TechnologiesBlast furnaces produce roughly 400 million tons of slag per year worldwide at a tapping temperature of around 1,500°C. Generally, wet granulation plants are used to cool down and process the material, using large quantities of water—it can take more than eight tons of water to treat one ton of slag.Dry Granulation of Blast Furnace Slag for Energy Recovery Dry Granulation of Blast Furnace Slag for Energy Recovery Around 300 kg of liquid slag is produced as byproduct while producing one ton of hot metal in a blast furnace (BF).This slag is at a temperature of around 1500 deg C and has a sensible heat of approximately 400 M Cal per ton.

Blast Furnaces normally generate 250 to 350 Kg of liquid slag for every ton of hot metal produced. This molten slag is at around 1400 – 1550 deg C temperature. Till seventies blast furnace (BF) slag was considered a waste product and was being dumped at a convenient place away from the blast furnace.

Ground Granulated Blast Furnace Slag in Concrete and its The ground granulated blast furnace slag (GGBFS) is a byproduct of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degreeTPT: Dry Granulation of Blast Furnace Slag for Heat RecoveryBlast furnace slag is known as a byproduct from the production of hot metal at integrated steel and iron mills. Approximately 300 kg of this liquid slag with a temperature of about 1500°C is tapped together with each ton hot metal. This results in a worldwide annual production of about 400 million tons of blast furnace slag.
