Usage of aluminum dross for slag treatment in secondary steelmaking to decrease amount of reducible oxides in ladle furnace

Sohn International Symposium on Advanced Processing of Metals and Materials -- AUG 27-31, 2006 -- San Diego, CAWOS: 000241814600029In this work it is aimed to assess the plant analytical data which appeared during efforts to decrease the effect of carry-over slag (basic oxygen furnace slag) that can not be prevented to leak during tapping of steel in the ladles. While the amount changes, carry-over slag that escaped to ladle, consists of appreciable amount of reducible oxides ("FetO" and MnO) which act as oxygen source for steel bath. By using aluminum dross, containing %30-35 metallic aluminum, which is a non-recoverable process outcome (discard) for most of the aluminum factories, slag reduction behavior will be analyzed together with other parameters such as reaction time, initial amount of total Fe+MnO, amount of reducing agent and reducing effect of soluble aluminum in steel bath while obtaining a slag composition which promotes higher desulphurization capacity and inclusion removal for liquid steel.Minerals, Met & Mat Soc, Acad Mexicana Ciencias Mat, Amer Foundry Soc, Amer Inst Chem Engineers, APMI Int, ASM Int, Asociac Argentina Mat, Assoc Iron & Steel Technol, Assoc Italiana Met, Australasian Inst Min & Met, Austrian Soc Met & Mat, Beijing Gen Res Inst Min & Met, Benelux Met, Brazilian Assoc Mat & Met, Brunei Darussalam Inst Chem, Ceram Soc Japan, Chem Soc Japan, Chem Soc Pakistan, Chem Soc Peru, Chilean Chem Soc, Chinese Soc Met, Cobalt Dev Inst, Colegio Ingenieros Chile, CSIRO, Czech Soc New Mat & Technologies, Danish Ceram Soc, Danish Chem Soc, Danish Met Soc, Electrochem Soc, Electrochem Soc Japan, Engn Conf Int, Eurometaux, European Ceram Soc, Federat European Mat Soc, Georgian Ceram Soc, German Soc Min, Met, Resource & Environm Technol, Gintsvetmet Inst, Gipronickel Inst, JS, Hellen Ceram Soc, Indian Inst Met, Inst Nonferrous & Rare Met, Inst Mat Engn Australasian, Inst Mat, Minerals & Min, Inst Met & Technol, Inst NonFerrous Met, Inst Argentino Siderurgia, Integrated Chemists Philippines, Int Aluminium Inst, Int Energy Fdn, Int Lead Zinc Res Org Inc, Iron & Steel Inst Japan, Israel Chem Soc, Japan Inst Met, Jordanian Chem Soc, Korean Acad Sci & Technol, Korean Chem Soc, Korean Inst Chem Engineers, Korean Inst Met & Mat, Malaysian Inst Chem, Mat Res Soc, Mat Soc Portugal, Met Sco CIM, Min Engn Int, Min & Mat Proc Inst Japan, Nonferrous Met Soc China, N Amer Thermal Anal Soc, Polish Assoc Met Engineers & Technicians, Portugese Chem Soc, Slovak Met Soc, Slovenian Ceram Soc, Slovenian Soc Mat, Soc Francaise Chimie, Soc Francaise Met & Mat, Soc Royal Chimie, Soc Min, Met & Explorat, Soc Chem Engn Japan, S African Inst Min & Met, Swedish Soc Mat Technol, Swedish Steel Producers Assoc, Technol Inst VZW, Amer Ceram Soc, Chem Soc Thailand, Finnish Assoc Min & Met Engineers, Canadian Min Journal, Ferrous Met Journal, Ind Minerals, Journal Tech Elect Mat, Magnesium Monthly Review, Mat Engn News, Mineral & Met Proc, Mineral Proc Journal, Min Journal, Nonferrous Met Journal, Ore & Met Publishing House, European Journal Min Proc & Environm Protect, Ausmelt, FLOGEN Technologies Inc, Korea Inst Geosci & Mineral Resources, Korea Zinc Co Ltd, LS Nikko Copper, Outokumpu Technol, Posco, Umicore Precious Met Refining, Xstrata Techno
