Highlights The granulation and heat recovery technologies towards molten slag of steel industry are reviewed. The working principle, research status, challenges and prospects of these technologies are analyzed. Centrifugal granulation combined with chemical heat recovery is the most perspective method among all technologies.
Dry slag granulation with heat recovery – Utilization of blast furnace slag heat energy Primetals Technologies, voestalpine Stahl, the FEhS – Building Materials Institute and the University of Leoben joined forces in an RD program to develop a new drygranulation technology using air to cool molten slag and recover the lost heat energy.

Iron and steel slag refers to the type of metal manufacturing slag that is generated during the process of manufacturing iron and steel products. The term "slag" originally referred to slag produced by metal manufacturing processes, however it is now also used to describe slag that originates from molten waste material when trash and other ...
Electric Arc Furnace slag. Produced during carbon steel production, Electric Arc Furnace slag is a manufactured aggregate which is a valuable source of oxides for the cement industry. The content of iron oxides (FeO x) in common Portland cement ranges between 3 and 6%. Possible sources for iron oxide are iron ore or, more preferably, byproducts ...
In addition to slag recovery, the liquid furnace slag and ladle slags are generally processed to recover the ferrous metals. This metals recovery operation (using magnetic separator on conveyor and/or crane electromagnet) is important to the steelmaker as the metals can then be reused within the steel plant as blast furnace feed material for ...

Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. 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
Proven metal recovery with simple, reliable equipment. If your mills are accumulating mountains of minus 3mm fines with varying moisture levels, then you''re in our sweet spot and we should talk.

Arc Furnace (EAF). Because iron in the steel slags is normally encountered in the form of steel (7–10 %), iron oxide and iron bearing minerals, the recovery of iron is achieved by crushing or grinding, screening and magnetic separation [17]. Similarly to iron slags, steel slags can also be used in other applications. • Alloy steel slags.
