1–8%. The slag basicity from BOF slag is in the range of 3.5, which is higher than the basicity of EAF slags with a basicity of about 2.0. The SMP slags often have an even higher basicity of around 46. Steel slag is a secondary resource of raw material in metallurgical plant. It can be directly taken back to

Possible Uses of Steelmaking Slag in Agriculture: An Overview

Steelmaking slag deriving from BOF process (using the Linz-Donawitz (LD) converter) comes from the pig iron refining process, wh ich converts molten pig iron and steel scraps into high quality steel. Most slags from steel pl ant derive from this pr ocess, with an average of 150-200 kg of slag generated per tonne of st eel produced.

Steel Slag an overview ScienceDirect Topics

The first stage of the scrap-based steel industry production generates EAF slag (EAFS) and a second stage is performed to refine the molten steel. The slag produced in the LF (LFS) is the result from steel refining and, therefore, it is generally a heavy metal carrier such as chrome, lead or zinc (CEDEX Ministerio de Fomento, 2018).

Apr 04, 2012 D. Sichen, in Fundamentals of Metallurgy, 2005 9.5.1 Slag–metal mixing. In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag–metal reactions.

Slag Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of
