Applications. 4. Iron production is via a continuous batch process with the iron and slag produced in the blastfurnace at a temperature around 1500ºC. For chemical uses, such as a raw material for manufacture of glass or mineral wool insulation and for agricultural applications, the chemical composition is quite important. Granulated Blast Furnace Slag Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than 4.75 mm (No. 1. Blast furnace static simulation model - furnace thermal state - wind temperature - oxygen enrichment - wind humidity Charging material data - chemical composition - price Requirements: - pig iron type and composition - slag basicity - furnace output External input parameters Internal input parameters It can also be referred as ‘GGBFS’ or ‘GGBS cement’ and the concrete which is made using GGBS is called ‘furnace concrete’ or ‘GGBS concrete’. Alumina is usually present, though the levels can vary quite widely between sources. ABS is a crystalline by-product produced by the solidification of molten blastfurnace slag. Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. Abstract. The chemical composition of slag from a given source varies within relatively narrow limits since raw materials charged into the furnace are carefully selected and blended. This gas is used for the furnace mills, in gas engines and for electricity and steam generation. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties. The Quantitative Effect of Blast Furnace Slag Composition and Temperature on the Kinetics of Potassium Evaporation. Executive summary 1 1. Electric-Arc-Furnace (EAF) Process of Steelmaking and Slag Generation . Grade 80 has a low activity index and is used primarily in mass structures because it generates less heat than portland cement. Blast furnace slag is composed of silicates and alumino silicates of lime . For every tonne of GGBS used in a concrete mix, the embodied CO 2 levels are reduced by around 900 kg compared to the use of one tonne of traditional Portland Cement. The chemical composition of blast-furnace slag is a significant factor in the potential performance of granulated material in cementitious uses. Blast furnace slag mortar samples were prepared using both sodium silicate and sodium hydroxide solutions as activator. To flux the silica produced during steelmaking, limestone and/or dolomite are added, as well as other types of slag conditioners such as calcium aluminate or fluorspar . formed in the BF slag. economy, since the blast furnace fuel rate increases and the productivity decreases. 4) sieve. Therefore, an in-depth understanding of phase composition and formation mechanism of slag crust is helpful to clarify the protection mechanism of copper stave, so as to control the growth of the slag crust and to increase the service life of copper staves. Blast furnace slag varies in composition and physical structure depending on the method of cooling of the slag. the top, to improve slag formation in the blast furnace. Table 1 Blast furnace observation models Fig. The basicity B2 of primary slag of the pellet, bosh slag, tuyere slag and final slag will then be 1.0, 1.1, 0.9 and 1.2, respec-tively.
