Oct 27, 2011 It can also be used to supplement the raw feed material for the manufacture of both mineral wool and cement.Steel Making Slag . Basic Oxygen Steel Slag BOS and Electric Arc Furnace Slag EAF Both BOS and EAF slag are very similar in their basic properties and are generally used in the same applications, with the exception of but a few.
Some natural rock is also used. Typically, slag wool insulation uses a minimum of 70 - 85 percent blast furnace slag, with the remaining volume of raw materials being natural rock. Application Stone and slag wool batts are available in pre-cut sizes that fit standard wall cavities and wall heights.
Typically, slag wool insulation uses approximately 70 blast furnace slag, with the remaining volume of raw materials being natural rock. Due to the similarities between the two types of mineral wool, an aggregate view will be used throughout this document that combines both slag and rock wools. Table 1 Mineral wool loose fill material content
In 1988, WHO 1 classified MMVF into four categories according to their manufacturing process and dimensions. Continuous-filament fibres are made exclusively from glass and have an approximate range of mean diameters of 615 m. Insulation wool includes rock wool, slag wool and glass wool. Rock and slag wools are

2.1.2 Blast furnace slag In the rst stage of moulding steel, impurities in the form of iron byproducts e.g. furnace slag will be removed. The second stage of steel manufacturing is to clean up the steel and free it once again from the iron impurities. The byproducts in the second stage are denoted blast-furnace slag BFS
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 120891987 manufacturing specification for granulated slag used in Portland Slag Cement.
