SAFETY GUIDELINES FOR IRON & STEEL SECTOR BLAST …

vi) Slag Granulation Plant (SGP) / Slag Dumping Yard: During the process of iron making, the impurities are fluxed and removed as slag. The hot liquid slag is made into slag granules by means of high pressure water jets in the Slag Granulation Plant in the Cast House itself (sometimes separate SGP is located at a distance from the furnace proper).

Mineral Resource of the Month: Iron and Steel Slag

Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten crude iron or steel; the slag is then removed from the liquid metal. For typical iron ore grades (60 to 66 percent iron), blast furnace slag output will be about 0.25 to 0.30 metric tons of slag per ton of crude iron produced.

86 IRON AND STEEL SLAG - USGS

slag (GGBFS). Air-cooled iron slag and steel slag are used primarily as aggregates in concrete (air-cooled iron slag only); asphaltic paving, fill, and road bases; both slag types also can be used as a feed for cement kilns. Almost all GGBFS is used as a partial substitute for portland cement in concrete mixes or in blended cements.

Usage of High-LOI Iron Ore Fines in Pellet Making ...

In pellet, green mix (base mix) with 20% high LOI iron ore fines found in the slag phase is more uniformly distributed and result in better bonding with oxide phases. From the above studies, it is confirmed that up to 20% high-LOI iron ore fines can be mixed in the pellet ore blend without affecting the properties of the pellet by applying ...

Loss on ignition - Wikipedia

Loss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science, particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating a sample of the material at a specified temperature, allowing volatile substances to escape, until its mass ceases to change.This may be done in air, or in some other reactive or inert atmosphere.

Types of iron and steel slag : NIPPON SLAG ASSOCIATION

Blast furnace slag. Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron.

Slag-What is it Good for? - USGS

We looked specifically at ferrous slag, the leftover material from the smelting of iron and steel, in the Chicago-Gary area of Illinois and Indiana. Ferrous slag is currently underutilized. Although the construction industry does use some slag as …

An Overview of Use of Linz-Donawitz (LD) Steel Slag in ...

The phosphorus content in LD slag is too high to be reused in iron making and one-hundredth percent of phosphorus go to the metal phase. The major phases present in LD slag in other parts of world are also studied, that contain some reactive mineral phase such as 2CaO.SiO 2, 3CaO.SiO 2, free CaO and MgO (Goldring and Jukes, 1997).Main mineral phases were identified by using X-ray diffraction ...

Characterization of Base and Subbase Iron and Steel Slag ...

ACBF slag has the highest content of aluminum and magnesium and the least percentage of oxides of iron as compared with other slags. Table 2 shows that the ACBF slag does not contain any measurable LOI, which indicates that no carbonates are present. The OH and BOF slags contain aluminum (3 to 4.5 percent), iron

Iron and Steel Slag Statistics and Information

Iron and steel slags are coproducts of iron and steel manufacturing. 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 ...
