Utilization of Eaf Metallurgical Slag in “green” Belite Cement
În acest studiu, zgură de cuptor cu arc electric (EAFS) colectată de la Sovel S.A., Grecia şi calcar şi argilă, de la compania de ciment Titan S.A., Grecia, au fost utilizate pentru producerea şi caracterizarea cimenturilor tip belitice. Trei tipuri de clincher au fost preparate: belitic fara adaos de zgură folosit ca referinţă (BC), unul cu 5wt% EAFS (BC5) şi un altul cu 10wt% EAFS (BC10). Ana...
متن کاملThe effective parameters on thermal recovery and reduction of iron oxides in EAF slag
Steelmaking slag of Mobarakeh Steel Company (MSC) has a high iron content which makes it unsuitable for conventional slag recovery; as in cement industries. On the other hand, EAF slag in this company is almost free of zinc because of using more than 90 percent DRI in the charge. Therefore, removal or recovery of iron from the slag can be a suitable solution to slag recovery in this company. In...
متن کاملUse of Slag/Sugar Cane Bagasse Ash (SCBA) Blends in the Production of Alkali-Activated Materials
Blast furnace slag (BFS)/sugar cane bagasse ash (SCBA) blends were assessed for the production of alkali-activated pastes and mortars. SCBA was collected from a lagoon in which wastes from a sugar cane industry were poured. After previous dry and grinding processes, SCBA was chemically characterized: it had a large percentage of organic matter (ca. 25%). Solutions of sodium hydroxide and sodium...
متن کاملNew Cathode Materials for Inert and Oxidizing Atmosphere Plasma Application
This study has been carried out to develop new cathode materials for two types of thermionic cathode. First is concerning to the tungsten electrodes for the plasma furnace and welding torches. The second one is the electrodes for air plasma cutting torch. Tungsten electrodes activated with a single and combined additives of rare earth metal oxides, such as La203,Y203 and Ce02,are produced and p...
متن کاملA Study on Suitability of EAF Oxidizing Slag in Concrete: An Eco-Friendly and Sustainable Replacement for Natural Coarse Aggregate
Environmental and economic factors increasingly encourage higher utility of industrial by-products. The basic objective of this study was to identify alternative source for good quality aggregates which is depleting very fast due to fast pace of construction activities in India. EAF oxidizing slag as a by-product obtained during the process in steel making industry provides great opportunity to...
