Laboratory studies by Baket et al., (1998) have shown that basic oxygen furnace slag can be utilized to remove phosphorous from an onsite waste water disposal system. The researchers postulated that the slag could be used in single pass, self-contained treatment modules in alternative treatment systems. Their studies showed that the slag removed
avoid disposal of these materials in landfills, and to beneficially use them. To date steel slag use on construction projects has not represented significant environmental problems. SCOPE: This interim policy addresses beneficial use of blast furnace and steel slag generated during iron and steel making. It has been
HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
The blast air causes the iron oxides, flux, and coke to react and iron, carbon monoxide and blast-furnace slag is produced. The molten iron and blast-furnace 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).
Blast furnace slag is a nonmetallic coproduct produced in the process in the production of iron from iron ore or iron scrap. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by mass of iron production.
Granulated blast-furnace slag is a co-product of the steel industry produced by adding a limestone flux to the ore to remove non-ferrous contaminants. As such, it may contain small quantities of hazardous heavy metals, including trace amounts of chromium, usually in solution in the glass.
2(a) Classification of the Chemical: Granulated Blast Furnace Slag is considered a hazardous material according to the criteria specified in REACH [REGULATION (EC) No 1907/2006] and CLP [REGULATION (EC) No 1272/2008] and OSHA 29 CFR 1910.1200 Hazard Communication Standard.
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...
EPA recommends that procuring agencies use the existing voluntary consensus specifications referenced below for cement and concrete containing fly ash and/or ground granulated blast furnace (GGBF) slag. Recommended Specifications for Cement and Concrete Containing Recovered Materials Cement ...
Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag.
Jan 22, 2016· Cleaning of Blast Furnace Gas. The process of liquid iron production in the blast furnace (BF) generates gas at the furnace top which is an important by-product of the BF process. This top gas of the blast furnace is at the temperature and pressure existing at the BF top and usually contaminated with dust and water particles.
May 03, 2010· Blast Furnace Modern furnaces are equipped with an array of supporting facilities to increase efficiency, such as ore storage yards where barges .
long reducing conditions could persist in near-surface slag-bearing grouted systems for radioactive waste disposal. The oxidant of most concern is oxygen (O2)—in the gas phase or dissolved in infiltrating water—which could react with the blast furnace slag and decrease the grout reductive capacity.
Even though it can be recycled, slag is frequently sent to landfills for disposal. In producing steel, iron ore is introduced into a blast furnace. Slag is produced during the separation of the molten steel from impurities in the furnace, which is comprised of a complex solution of silicates and oxides that congeals upon cooling.
eventually, sent to slag disposal sites. In comparison, all of the blast furnace slag (a by-product of the ironmaking industry) generated each year is fully reutilized by the cement and concrete industry. As the current methods of stockpiling and landfilling are not sustainable, disposal of steel slag
