Blast Furnace - an overview | ScienceDirect Topics

Steel slag is a by-product of the steel-making process formed from the reaction of flux such as calcium oxide with the inorganic nonmetallic components present in the steel scrap. Two types of steel slag can be distinguished: (1) Basic oxygen furnace (BOF) steel slag. (2) Electric arc furnace (EAF) steel slag.

The primary applications for steel slag in the United States are its use as a granular base or as an aggregate material in construction applications. Disposal. While most of the furnace slag is recycled for use as an aggregate, excess steel slag from other operations (raker, ladle, clean out, or pit slag) is usually sent to landfills for disposal.

electric arc furnace - an overview | ScienceDirect Topics

Electric arc furnace melting is the primary method of manufacture in steel foundries. A basic lined furnace is necessary since the manganese slag will readily attack acid refractories. The melt charge consists of a combination of recycled manganese castings, gates, and feeder heads plus low-phosphorus ferromanganese, silicomanganese, and ...

Born from Iron and Steel - Phoenix Slag Services

The lime combines with the silicates, aluminum oxides, magnesium oxides, manganese oxides and ferrites to form steel furnace slag, commonly called steel slag. Slag is poured from the furnace in a molten state. After cooling from its molten state, steel slag is processed to remove all free metallics and sized into products.

Understanding Electric Arc Furnace Steel Making Operations

While making C steel heats a minimum of slag carry over is aimed. A new slag cover is built during tapping. For ladle furnace operations, a calcium aluminate slag is a good choice for the control of S. Slag forming compounds are added in the ladle at tapping so that a slag cover is formed prior to transfer to the ladle furnace. Furnace turnaround

Common Uses for Slag | National Slag Association

Basic Oxygen Furnace Steel Slag (BOF or Steel Furnace Slag) This slag Is formed when molten Iron, scrap metals and various fluxes, such as lime, are oxidized by injecting large amounts of pure oxygen into the molten iron mix to create molten steel and molten slag. Slow cooling of the molten slag produces a dense rock material.
