Blast furnace slag granulation plant technology - Millennium SteelThe blast furnace produces large amounts of liquid slag, which can be processed into valuable raw materials for the cement and other industries. For example, in cement production, granulated slag can replace up to 70% of the more costly Portland clinker. The slag volume depends on the quality of the raw materials used.granulated slag processing,Blast furnace slag granulation at cast house | ispatguruMay 5, 2013 . The process of slag granulation involves pouring the molten slag through a high pressure water spray in a granulation head, located in close proximity to the blast furnace. Granulation process is the controlled quenching of the slag in cold water which does not give time for crystalline growth to take place.

Iron and steel slag - USGS Mineral Resources Program

Dec 31, 2011 . Iron (blast furnace) slag accounted for about 50% of the tonnage sold and had a value of about $250 million; nearly 85% of this value was granulated slag. Steel slag produced from basic oxygen and electric arc furnaces accounted for the remainder.2 Slag was processed by nearly 30 companies servicing.

Iron and steel slag - USGS Mineral Resources Program

firms, with 5 processing only iron slag, 1 processing only steel slag, and the remainder processing both iron and steel slag. Iron-blast-furnace slags were processed at 27 facilities in 12 States; these slags consisted of air-cooled, expanded, and granulated types. Steel slags from open-hearth, basic oxygen, and electric arc.

Granulated blast furnace slag - Mineral Products Association

Slag. Granulated blast furnace slag (GBS). What is GBS? Granulated Blast furnace slag (GBS) is a light coloured 0/4mm glassy sand produced by the rapid quenching of molten blast furnace slag using large volumes of water. Production and Processing.

5.1 Introduction: blast furnace slag and steel furnace slag applications

Granulated blast furnace slag can have up to 99.5% reactive glassy material, which accounts for its self-cementing properties. Stabilising binder: one of the major benefits of using slag products in a stabilised pavement is the slow rate of the cementation process. The pavement material can be reworked up to two days or.

Slag Cement Association > About Slag Cement > IS-01

The molten iron is sent to the steel producing facility, while the molten slag is diverted to a granulator. This process, known as granulation, is the rapid quenching with water of the molten slag into a raw material called granules. Rapid cooling prohibits the formation of crystals and forms glassy, non-metallic, silicates and.
