The present invention relates to a system for drying steelmaking slag using waste heat. The system includes: a slag port; a tundish; a gas nozzle; a cooling fence; a bucket elevator; a sieve screen; a separator; a dryer that receives the waste heat from the separator, dries the slag through heat exchange, transfers the slag to down-line equipment, and transfers the heat exchanged waste heat to
Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties.
Supplementary cementitious materials such as blast-furnace slag (BFS) and pulverised-fuel ash have been used as a partial replacement for Portland cement (PC) in UK and international nuclear waste encapsulation for many years (Angus et al., 2010; Sharp et al., 2003).Encapsulation in a cementitious wasteform is the current preferred method of disposal of intermediate level waste in the UK
Abstract: A large amount of solid waste slag is generated in the production process in iron and steel enterprises. As for enterprise which takes blast furnace as the process, blast furnace slag accounts for more than 50%.

A slag disposal method for disposing of slags produced in furnaces during iron or steel making processes comprises employing the steps of magnetic sorting of masses of crude slags of a size greater than a value ranging between 300 to 500 mm obtained from the furnaces into slags rich in iron (above about 50 to 60 percent) and slags not rich in iron (below about 50 to 60 percent) and then
Supplementary cementitious materials such as blast-furnace slag (BFS) and pulverised-fuel ash have been used as a partial replacement for Portland cement (PC) in UK and international nuclear waste encapsulation for many years (Angus et al., 2010; Sharp et al., 2003).Encapsulation in a cementitious wasteform is the current preferred method of disposal of intermediate level waste in the UK
Even though it can be recycled, slag is frequently sent to landfills for disposal. In producing steel, iron ore is introduced into a blast furnace. Slag is produced during the separation of the molten steel from impurities in the furnace, which is comprised of a complex solution of

Slags, especially waste from slag processing and unprocessed waste slag, are classifiable in the Green List if suitable for admissible recovery operations (e.g. recovery in the construction industry or use as sand-blasting products) and if they in no way constitute hazardous waste (e.g. because of contamination, especially in the case of many
Steel slag is a waste material produced during the process of steel making. For many years, a large amount of steel slag was deposited in slag storing yards, occupied farmland, silted rivers and
Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.
