May 05, 2013· Blast furnace slag granulation at cast house. ... Water vapours generated during the slag granulation are emitted through a stack normally made of stainless steel. Factors affecting granulated slag quality. The following parameters affect the quality of the granulated slag.
Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.

The observation by Altun, et al. [34] showed that the cement with 30% steel slag fine powder addition qualified the Turkish standard requirements for Portland cement. Huang, et al. [35] prepared a cementitious material by utilizing phosphogypsum(PG), steel slag (SS), granulated blast-furnace slag (GGBFS) and limestone(LS).
The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.
A review of the different types of steel furnace is provided, the slag produced in each of them are described and the cooling or recovery methods that determine the characteristics of the slag and concrete are analysed. The most-used slag is produced in a blast furnace in the manufacture of cements or as aggregates.
2.3 Stainless steel slag waste 93 The stainless steel slag waste used in this investigation was obtained from a producer of 94 ferritic stainless steel produced by a steel plant Acerinox in Algeciras, Cádiz, Spain. The 95 steel slag is produced during the direct reduction of iron in an electric arc furnace.
Slag : Air-cooled blast furnace slag (ABS) What is ABS? ABS is a crystalline by-product produced by the solidification of molten blastfurnace slag. Production and Processing. Iron production is via a continuous batch process with the iron and slag produced in .

SLAG Slag is a grainy, grey and metallic byproduct of steel production that can be used to produce slag cement and composite cement. One of the most sustainable construction materials available, slag decreases greenhouse gas emissions and the use of materials. Shun Shing Group trades both granulated
silicon metal blast furnace slag silicon metal blast furnace slag description 1 . The siliocn slag is much cheaper than purity silicon metal, and has many industrial applications. The silicon slag powder can be made silicon briquette which has far and wide market at home and abroad. 3 .
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.Ground -granulated blast furnace is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing ...
Slag : Air-cooled high alloy electric arc furnace (EAF) and stainless steel slag (AOD) What Are High Alloy and Stainless Steel Slags? High alloy and stainless steel slags are by-products of the manufacture of these steels by either the electric arc furnace process (EAF) or the argon oxygen decarburisation (AOD) process.

The chapter describes the characteristics of blast furnace slag and steel slag, the main two types of ferrous slag. Blast furnace slag is created during the melting and reduction of iron ore in a blast furnace, while steel slag is produced during the conversion of hot metal to crude steel or during the melting of scrap in various kinds of furnaces.
Paul Wurth has approached the topic of dry slag granulation with a simple but effective method in which steel spheres and liquid slag are mixed to achieve fast cooling of the blast furnace 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.
Steel slag can also be produced by smelting iron ore in a basic oxygen furnace. According to methods for cooling molten steel slag, steel slag is classified into five types: natural air-cooling steel slag, water-spray steel slag, water-quenching steel slag, air-quenching steel slag, and shallow box chilling steel slag .
