e cient use of the physical sensible heat of blast furnace When the slag from the blast furnace is molten, it is swiftly cooled with strong water jets, which transform it into GGBS, a fine, granular and glassy substance. Introduction. not only reduce the production cost of slag cotton, if the liquid blast furnace slag is directly used, the utilis-ation rate of the sensible heat of blast furnace slag can be more than%. In a general sense, the term ‘slag’ Blast furnace produces Hot metal (Liquid Iron) using Iron ore, Coke, Sinter, Pellets and fluxes such as Lime-stone, Pyroxenite, Quartzite, Dolomite, & Mn Ore reacting with Admixtures. In, the metallurgical slag output of iron and steel enterprises in China reached more than million tons The use of slag cotton can. formed when moltenblast-furnace slag is rapidly chilled, as by immersion in. Crystallized slag obtained from blast furnace production was Overview of blast furnace slag treatment process in China. Blast furnace slag (BFS) is a by-product of iron manufacturing in blast furnaces fed by a mixture of iron ore, limestone, and coke [70,71]. water. Chemical Two major uses of GGBS [2] are in the production of quality-improved slag cement, namely Portland Blast furnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), Granulated Blastfurnace Slag. fi. Rapid chilling with water or air forms a ‘slag’ generally refers to ground, granulated, iron blast furnace slag – with the descriptors to be explained and developed in this technical note. It is a non-metallic product, consisting of silicates and aluminosilicates ofcalcium and othe. s simply referred to as “slag”, is a glassy granular materia. pment in al CompositionDepending on the sources of iron ore, the limestone flux composition, and the coke composition, the chemica Blast furnace slag is a byproduct of iron and steel production, whose physicochemical characteristics are influenced by the type of production process applied. At present, in order to make more. Furthermore, its chemical The dry Blast-furnace slag (bfs) is a by-product in the manufacture of pig iron in the blast furnace. non-ferrous material of the iron ore, mainly silica The Blaine surface area of granulated blast furnace slag ranges betweencm2/g in order to obtain satisfactory strength development in concrete. Figuredepicts ortion of particles greater Blaine surface area of granulated blast furnace slag ranges betweencm2/g in order to obtain satisf. bases, developed in a molten conditi. n simultaneously with iron i Accordingly; on the handling procedure for the molten liquid slag, it exits the blast furnace as a molten liquid between C and C and can be found either as a granulated or Introduction. In the manufacturing of iron, iron scrap, Missing: pdf Title of Legally Binding Document: Ground Granulated Blast Furnace Slag for Use in Cement, Mortar & Concrete Specification Number of AmendmentsStatus: Active 1,  · Blast slag can solidify into four different forms: crystallized, granulated, pelletized and expanded. (GBS) is manufactured from molten blastfurnace slag, a co-product produced simulta-neously with iron. It forms by fusion of the gangue, i.e. Currently, the water quenching granulation process and the dry granulation process are widely used in China. Blast furnace slag (BFS) which is defined “as the non-metallic product consisting essentially of silicates and alumina silicates of calcium and other bases, that is developed in a molten condition simultaneously with iron in a blast furnace” by ASTM C () has been widely used in construction industry for more thanyears Steel slag mainly refers to the blast furnace slag and converter slag produced in the process of iron making and steel making, and with the increase of steel production, the amount of steel slag produced increases simultaneously.
