Blast Furnace Slag is a co-product of the iron making process. It is removed from the blast furnace and allowed to cool. ASMS then further process the blast furnace slag

How to divide molten Metal from Slag (the Blast Furnace)

Nov 09, 2007· The molten iron is denser than the waste slag, so it collects at the bottom. Most modern blast furnaces are designed so that when a given amount of ore is put in, the slag line will always be Slag Wikipedia,Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste Sustainability-Environmental-Waste Management, Recycling,Use of iron and steel slag in place of mined and quarried rock and mineral aggregates saves these natural resources and reduces impact on the environment. Blast furnace slag is used in cement manufacturing, asphalt mixes, glass manufacturing, precast concrete, wallboard, mineral wool and sub-base for road and interstate highway construction.

Iron and Steel Slag Statistics and Information

In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed.Slag Aggregate an overview ScienceDirect Topics,A synthetic aggregate may also be the byproduct of manufacturing and a final burning process—blast furnace slag is an example of a synthetic aggregate.
