Blast Furnace Slag Disposal System

Slag Disposal Sites - EnviroBlend

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 …

Blast Furnace Slag - Material Description - RMRC

The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product. This molten iron product can be cast into iron products, but is most often used as a feedstock for steel production. Blast furnace slag is a nonmetallic coproduct produced in the process.

Blast Furnace Slag | National Slag Association

Blast furnace slag is allowed to slowly cool by ambient air, is processed through a screening and crushing plant and is processed into many sizes for use primarily as a construction aggregate. Common uses are as aggregates in ready-mix concrete, precast concrete, hot mix asphalt aggregate, septic drain fields and pipe backfill.

Environmental Information | National Slag Association

Physical and stone Characteristics of Blast Furnace, Basic Oxygen Furnace, and Electric Arc Furnace Steel Industry Slags. Because slag contains heavy metals at concentrations that are higher than most soil, questions have been raised regarding the need to evaluate the potential human health and environmental hazards associated with current applications.

Ground granulated blast-furnace slag - Wikipedia

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing ...

Blast Furnace - an overview | ScienceDirect Topics

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 …

First and foremost, it’s a recycled product – created from blast-furnace slag otherwise destined for disposal. The energy, emissions and raw materials required to produce slag cement is a fraction of that needed for traditional portland cement.

Disposing Of The Slag. Continued

The "hot pot" method of handling slag is economical for a large plant of furnaces, and where dumping room is available within a reasonable distance; but in congested districts where the only available land between high bluffs and a river is a narrow strip of bottom, every inch of which is necessary for plant and railroad tracks, it is not always easy to find a place in which to dispose of the slag without a long …

Estimated Longevity of Reducing Environments in Grouted ...

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.

Slag - Wikipedia

Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route. To flux the silica produced during steelmaking, limestone and/or dolomite are added, as well as other types of slag conditioners such as calcium aluminate or fluorspar. The major components of these slags therefore include the oxides of …
