slag produced at steel melting shop is known as steel slag. Slag output obtained during pig iron and steel production is variable and depends mainly on composition of raw materials and type of furnace. Typically, for ore feed containing 60 to 65% iron, blast furnace (BF) slag production ranges from about
May 09, 2018· Chemical Composition of Ground Granulated Blast Furnace Slag. The composition of slag essentially depends on the raw materials used in the iron production process. Typical chemical composition contains calcium oxide 40%, silica 35%, alumina 13% and magnesia 8%.

Pig Iron Production Blast Furnace Route More than billion tonnes of blast furnace iron was produced globally in 2016. Blast furnace economics are such that larger units have lower unit production costs, hence there has been a trend to bigger and bigger furnaces.
worldsteel publishes monthly production statistics for crude steel, direct reduced iron (DRI) and blast furnace iron (BFI). These are global steel statistics per country, including the main top steelproducing countries, China, Japan, India, and USA.
Slag is mainly used for the production of cement, either as a cement mixture, can also be made nonclinker cement. After fine grinding blast furnace slag can be used as the main raw material for the production of slag powder. It can replace silicon bath soil insulation packing and save cost.
The blast air causes the iron oxides, flux, and coke to react and iron, carbon monoxide and blastfurnace slag is produced. The molten iron and blastfurnace slag is collected at the base of the furnace, while the gases are recirculated for fuel in the sinter process, after separation of particulate material (Cooper, 2005).

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.
Blast furnace slag is used in the production of cement (iron Portland and blast furnace cement). Aircooled blast furnace slag is formed by allowing the molten slag to cool relatively slowly under ambient conditions; final cooling can be accelerated with a water spray.
Granulated Blast Furnace Slag is obtained by rapidly chilling (quenching) the molten ash from the furnace with the help of water. During this process, the slag gets fragmented and transformed into amorphous granules (glass), meeting the requirement of IS 12089:1987 (manufacturing specification for granulated slag used in Portland Slag Cement).
