Nov 20, 2014 Ground granulated blast furnace slag (GGBFS) and alkaline activators. The original base material of the studies was an industrial GGBFS. This slag was modified with pure oxides to reach the desired composition and re-molten in a graphite crucible under nitrogen atmosphere at temperatures between 1,550 and 1,650 C.

Blast furnaces may have the following ancillary facilities: a stock house where the furnace burden is prepared prior to being elevated to the furnace top by skip cars or a belt conveyor system; a top-charging system consisting of a vertical set of double bells (cones) or rotating chutes to prevent the release of furnace gas during charging; stoves that utilize the furnace off-gases to preheat

Irregularities in Blast Furnace during Operation – IspatGuru

Nov 02, 2013 The different causes for channeling to occur in the blast furnace are charging of excessive fines, improper distribution of the burden material inside the furnace and high level of liquid iron and liquid slag in the hearth. In case of fines charging, the channeling leads to the increase of the heat load at the walls of the blast furnace.

Laboratory studies by Baket et al., (1998) have shown that basic oxygen furnace slag can be utilized to remove phosphorous from an onsite waste water disposal system. The researchers postulated that the slag could be used in single pass, self-contained treatment modules in alternative treatment systems. Their studies showed that the slag removed

Blast Furnace Slag In the production of hot metal, the blast furnace is charged with iron-bearing materials (iron ore, sinter, pellets, etc.), flux (limestone Figure 3-6. Ironmaking Iron Units, U.S. 2000 and/or dolomite), and fuel (coke). (SRI 2001)Two products are obtained from the bottom of the blast furnace: molten iron and slag.

Jun 01, 2016 The high-temperature blast furnace slag is conventionally treated by water quenching (WQ) method with enormous waste heat unrecovered. To address this issue, dry slag granulation (DSG) technology has been proposed to recover the waste heat from molten slag.

Ground granulated blast furnace slag (GGBFS) has similar cement-like properties to Portland cement. The glass content of GGBFS varies between 60 % and 100 % by volume, depending on the granulation process. For many applications, blast furnace slag cements have even better properties than conventional Portland cements. 3 Global market data
