Characterization of Ladle Furnace Slag from Carbon Steel ...

Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers' current waste footprint.

STEEL SLAG : THE HIGH PERFORMANCE INDUSTRIAL AGGREGATE

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being ...

Sep 29, 2014· The slag has been used as an effective aggregate for road making. Vitrified ceramic tiles have also been developed from the EAF slag. Continuous casting. Major waste materials generated in the continuous casting process is continuous casting scale, refractory waste, scrap, slag and muck.

Iron Ore Smelting Process - Bright Hub Engineering

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.

Industrial uses of slag—The use and re-use of iron and ...

Steel - Steel - Ladle metallurgy: The carrying out of metallurgical reactions in the ladle is a common practice in practically all steelmaking shops, because it is cost-efficient to operate the primary furnace as a high-speed melter and to adjust the final chemical composition and temperature of the steel after tapping.
