Oct 27, 2011 With world steel production now well over a billion tonnes per year, the slag that arises from some of the processes involved is a major resource. Traditionally it has been used mainly as an aggregate but for some types there are other applications, such as a
11.18.2 Process Description1,4,5 Most mineral wool produced in the United States today is produced from slag or a mixture of slag and rock. Most of the slag used by the industry is generated by integrated iron and steel plants as a blast furnace byproduct from pig iron production. Other sources of slag include the copper, lead, and phosphate

U.S. ferrous slag production, but domestic slag sales1 in 2019 were estimated to be 17 million tons valued at about $470 million. Blast furnace slag was about 50% of the tonnage sold and accounted for 88% of the total value of slag, most of which was granulated. Steel slag produced from basic oxygen and electric arc furnaces accounted for the

Dec 01, 2013 The BF slag is discharged at a temperature of 1450–1550 C and thus, the total energy carried by BF slag amounts to 11 million tonnes standard coal (approximate 1770 MJ of energy per tonne BF slag), corresponding to 13.0% of consumption in the blast furnace process. Meanwhile, the production of steel slag is over 70 million tonnes in recent

Blast furnace slag is a combination of silica and other non-ferrous components of iron ore, ash from coke used as a reducing material, and limestone auxiliary material. Because its specific gravity is less than that of pig iron, during the heating process the molten slag rises above the pig iron allowing it to be easily separated and recovered

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 in metal smelting, they can also serve other purposes, such as assisting in the temperature control of
