Blast Furnace Slag is shaped when iron pellets or iron ore, coke, and limestone or dolomite (Flux) are heated together in a blast furnace. When the metallurgical melting procedure is finished, the lime in the flux has been chemically united with the aluminates and silicates of the ore and coke ash to procedure an outcome named blast furnace slag which is non-metallic. Throughout the period of chilling and becoming hard from its melted state, Blast Furnace Slag (BFS) can be cooled in numerous ways to procedure any of the different types of BFS products.
Burning substantial and ore are supplied from the top while airflow is abounding from the bottom of the chamber. This imposition the chemical response to take place all over the ore, not only at the superficial. Granulated slag is quickly cooled by large amounts of water to produce a granule which is sand-like and is mainly ground into a cement generally known as Ground Granulated Blast Furnaces Slag (GGBFS), or Type S slag cement. It also can be mixed with Ordinary Portland Cement Clinker to make a combined Type 1 cement.
GGBFS is formed when Granulated Blast Furnace Slag (GBFS) is an additional processed or ground using cement clinker grinding skill.
On an unplanned inspection, GGBFS can be off-white in look and could pass for a powder fineness naturally between 380m2/kg – 420m2/kg.
Subsequently, molten slag has been quenched quickly by passing it through high compression, high capacity water sprays, the heat energy controlled in the molten slag causes it to explode and promptly procedure Granulated Blast Furnace Slag (GBFS).
We are proud to let you know that Arij Global Trading supplies Ground Blast Furnace Slag (GBFS) and also Ground Granulated Blast Furnace Slag (GGBFS) with high quality. In case you are interested, please take a look at our specifications here.
