A Study of EAF HighChromium Stainless Steelmaking Slags
A good slag practice is essential for production of a highquality 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 Stainless Steel Slag on various proportions in Concrete (25% 50% 75% 100%) The basic objective of this study was to identify alternative source of aggregates and cement and to produce new type of concrete made of stainless steel slag as a green concrete And to control the manufacturingPerformance of Stainless Steel Slag in Concrete StructuresJul 01, 2017 In the first process stage (BOF or EAF), steel slag is a byproduct of the aggregate, However, in the second stage of manufacturing stainless steel (ladlefurnace steel refining), stainless steel slag is generated as dust The dusts are the most important byproduct of stainless steelmaking and refining operationsEffect of stainless steel slag waste as a replacement for

The EAF slag has a lower density than steel and therefore floats on top of the molten steel Once the steel has been tapped into a ladle, the slag is either poured from the furnace onto the floor where it is cooled and removed for further processing, or into slag pots where specially designed vehicles are used to transport the slag to purpose Several studies 38 of steel slag in secondary applications will remain important5 have investigated the stabilization potential of numerous com 39 The presence of harmful elements such as Cr in stainless pounds16,17,21,22 but recently, Kim and Hong22 confirmed that 40 steel slag,6,7 however, restricts the fields of applicationBorate Distribution in Stabilized StainlessSteel SlagJan 24, 2016 Stainless steel does not readily corrode, rust or stain with water as ordinary steel does Wrought iron Cast iron assumes its finished shape the moment the liquid iron alloy cools down in the mold Wrought iron is a very different material made by mixing liquid iron with some slag The result is an iron alloy with a much lower carbon contentIron Ore Distribution across the World PMF IAS
