slag processing and applications thedugong. 5.1 Introduction: blast furnace slag and steel furnace slag applications. The properties of iron and steel slags can vary greatly, depending on the processing done once the slag is removed from the furnace.
Blast Furnace. After mining, various kinds of iron ores are brought to the blast furnace which is the starting process for refining iron ores or mined ores and for the production of pig iron.Blast furnace was invented in 14th century. A typical blast furnace along with its various parts is shown in Fig. 1.
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. 4 sieve) in diameter to dense, sand-size grains passing a .

The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route.
Zinc processing - Zinc processing - The zinc-lead blast furnace: Sintered zinc and lead concentrates, mixed with metallurgical coke, are charged into the top of a shaft furnace, into which preheated air is blown through nozzles, or tuyeres, at the base (see figure). This procedure is similar to that followed in an iron blast furnace, with the important difference that the major products of ...

Stearns Magnet LDP Drum Separator. The heavy-duty construction permanent LPD Drum stands up under even the most punishing slag, blast furnace, foundry or auto scrap operations. Simple, rugged construction minimizes downtime. Sealed cylinder O-ring construction permits use in all environments.
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.
It is necessary to pass the granulated slag under a strong magnet in order to remove any particles of metallic iron. Blast-furnace slag is used in making-four classes of cement— Puzzolan, or ordinary slag cement, usually simply called slag cement. Slag Portland cement, which may be a true Portland cement.
Iron processing - Iron processing - Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
