A Study of EAF High-Chromium Stainless Steelmaking

2011-5-16  A good slag practice is essential for production of a high-quality stainless steel. In addition, the electrical and material efficiency of the electric arc furnace (EAF) can considerably be improved by a good slag practice. The metallurgical properties of the slag are strongly influenced by its high-temperature microstructure.

Metal slag processing // REMONDIS´ Lippe Plant

The special feature of LEGRAN’s metal slag processing system at the Lippe Plant is the way the material is treated. The slag and spent refractories need to be pulverised before they can be processed and this job is carried out by a rod and ball mill which dates back to the time when the site used to produce aluminium.

Steelmaking Slag - an overview ScienceDirect Topics

2012-4-4  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
