Slag's ain't Slag's. SLAG is a broad term covering all non metallic co products resulting from the separation of a metal from its ore, Its chemistry and morphology depends on the metal being produced and the solidification process used. Slags can be broadly categorized as ferrous (iron/steel) and nonferrous (copper,...
Fig 6: Colour of GGBS. Ground granulated blast furnace slag „GGBS‟ is one of the „greenest‟ of construction materials. Its only raw material is a very specific slag that is a by product from the blast furnaces manufacturing iron. Manufacturing of „GGBS‟ utilises all of .
Two types of blast furnace slag such aircooled slag and granulated slag are being generated from the steel plants. In most cases, this slag is produced in the form of granulated slag. The specific gravity of the slag is approximately with its bulk density varying in the range of 1200 1300 kg/m3.

What is Slag Cement. This process, known as granulation, is the rapid quenching with water of the molten slag into a raw material called granules. Rapid cooling prohibits the formation of crystals and forms glassy, nonmetallic, silicates and aluminosilicates of calcium.
Slag Granulation Systems. Slag granulation using water sprays is now an established technology that not only simplifies blast furnace casting floor operations but also provides an economical route for producing of a valuable raw material for a host of industries. The slag granulation plant comprises three sections: for granulation, dewatering and storage.
Sep 30, 2008· Abstract. Blast furnace slag samples with phase separation structure were prepared by remelting and then water quenching process. By use of XRD, DTA and SEM technologies in combination with mechanical property experiment, the structure characteristics of samples were determined and their effects on cementitious reactivity were investigated.
PDF | This research focused on the design of a ferrochrome – slag mechanical separator for a company in Harare, Zimbabwe. The company's current production is 420 tonnes of alloy per month. The ...
Step 3: determination of water content of SCC Now the water to effective cementitious materials content ratio of self compacting concrete with slag is given by ws /(cs + k28 g), where 'ws' is the water content of self compacting slag concrete which is to be determined.
7) Shells unfossilized shell of fresh water clams 8) Coal, wood, and other foreign materials 9) Materials with loosely cemented grains and/or a weathered coating Coke and Iron Coke and iron are of concern only with the slag materials. Coke is an ingredient in the steel making process. Slag .
Ground granulated blastfurnace slag Groundgranulated blastfurnace slag ( GGBS or GGBFS ) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
2. At the tiltingfurnaces, after a thorough fusion has taken place and the furnace is prepared for a separation of the slag and matte, it is tilted and a man with a long hoe skims the slag from the furnace into a trough, from which the slag is granulated and sluiced to the river like the blastfurnace slag .
iron. This enables ease of separation of the slag from the furnace. Upon removal from the furnace, the cooling method used determines the type of slag produced. If the natural cooling process is used, with water being sprayed over the slag, it is categorised as an aircooling slag.
GGBF slag has been used in concrete in Japan and Western Europe since the 1940s. Concrete containing slag is estimated to comprise approximately 20 percent of the hydraulic cement produced in Europe. Blast furnace slag is used predominately as base and concrete aggregate. It can also be granulated and used in the manufacture of cement.
EFFECT: increasing filtration speed of residual water, reducing the wear of dehydrator parts contacting abrasive particles of granulated slag, and simplifying the design. 2 cl, 2 dwg The invention relates to techniques for dewatering of granulated slag, and is intended mainly for use in prirechnyh installations for granulating metallurgical slag.
