Oct 18, 2017 Blast furnace slag BFS is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.
Lump blast furnace slag is formed by slowly cooling the liquid slag in the slag beds. Afterwards, it is prepared crushed or screened and used as a material for road and pathway construction. Granulated blast furnace slag is produced by quickly cooling the liquid slag with water in the granulation plants.

Granulation of the excess hot metal is a process that deals with these issues and produces a by-product - Granulated Pig Iron GPI - that can readily be used internally, for example as BOF coolant, or sold to third parties as feedstock for electric arc furnaces, cupolas and induction furnaces.
GBFS Granulated Blast Furnace Slag GBFS can be used like sand as an additional aggregate for building materials. Granulated Blast Furnace Slag is obtained by quickly chilling quenching the molten ash from the furnace with the help of water. Throughout this procedure, the slag becomes fragmented and changed into amorphous granules glass.

Slag cement specifications are described and slag produced from European and North American blast furnaces ...
Jan 01, 2010 Important properties of sinter for blast furnace process are reducibility, size and size distribution, cold and hot strength, and softening and melting behavior. Typical sinter suitable for blast furnace process is from 15 to 25 mm, as is illustrated in Figure 1.1.10 22.Another important property is the disintegration of sinter in reduction, which occurs during the transformation of hematite ...
The process is time consuming and hence expensive thereby increasing the cost of producing granulated blast furnace slag. Another process which attempts to overcome the increased costs of granulating slags in a partially closed system is described in U.S. Pat. No. 4,046,542 issued to Kees J. Schmidt entitled Method and Device for Granulating ...
The main objective of the slag granulation plant is to process liquid blast furnace slag into valuable raw materials for the cement and construction industries. The value of the slag depends on its characteristics such as mineralogical, chemical, physical and mechanical properties, glass content, structure and moisture content.
Mar 06, 2019 The main objective of the slag granulation plant is to process liquid blast furnace slag into valuable raw materials for the cement and construction industries. The value of the slag depends on its characteristics such as mineralogical, chemical, physical and mechanical properties, glass content, structure and moisture content.
The use of slag cement as a cementitious material dates back to 1774, when a mortar was made using slag cement in combination with slaked lime Mather 1957. In 1862, a granulation process was proposed to facilitate removal and handling of iron blast-furnace slag leaving the blast furnace. The use of granulation produced glassy material that played
