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

In 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.


Use of granulated blast furnace slag and lime in cement-bentonite slurry wall construction
Talefirouz, D.; Çokça, Erdal; Omer, J. (2016-01-01)
This paper describes an experimental investigation on the use of ground granulated blast furnace slag (GGBFS) and lime as stabilizers for cement-bentonite (CB) slurry used in constructing vertical barrier walls. The primary objective is to develop a blended material, which can reduce the permeability and also enhance the strength of CB slurry walls with a shortened curing time. Mixtures comprising various proportions of cement, bentonite, GGBFS, and lime were prepared and tested for particle size distributi...
Application of acoustic emission for damage classification and assessment of corrosion in pre-stressed concrete pipes
Goldaran, Reza; Türer, Ahmet (Elsevier BV, 2020-08-01)
The present study describes the usage of the AE technique for detecting different types of damage in corrosion process with characterization of corresponding AE sources in pre-stressed concrete cylinder pipes. Firstly, several small-scale tests were implemented to specify the characteristics of AE sources including water absorption of concrete, hydrogen bubbles bursting and concrete cracks, as well as determining the appropriate sensors positions. Later on, a full-scale pre-stressed pipe was subjected to co...
Use of aluminium dross for slag treatment in secondary steelmaking to decrease amount of reducible oxides in ladle furnace
Aydemir, Onur; Geveci, Ahmet; Department of Metallurgical and Materials Engineering (2007)
In this study it was aimed to analyse refining processes such as decreasing reducible oxide content of ladle slag with affecting parameters in low carbon aluminum killed grades and for the research Erdemir low carbon steel grades 7112K and 7110K are selected. There was a negative correlation between reducible oxide amount in ladle slag and desulphurization capacity of ladle slag with metal-slag reaction and steel internal cleanliness. To refine these properties of slag, aluminium dross, which was aluminium ...
Utilization of wet-handled and dry-handled coal bottom ashes in portland cement based composites
Tirkeş, Sera; Akgül, Çağla; Department of Civil Engineering (2021-9-7)
Coal bottom ash (BA) is a coarse, granular, incombustible by-product collected from the bottom of coal-burning furnaces. Traditionally, it has been handled by wet-handling systems (WHS) that use large amounts of water for cooling and conveying BA. WHS relies on established technologies such as impounded hoppers or submerged scraper conveyors. However, the need for water treatment, environmental concerns such as contaminated water, and high operational costs caused a necessary shift from WHS to more sustaina...
Optimization of the aquifer remediation costs and design with pulsed pumping
Aksoy, Ayşegül (null; 1999-06-10)
(No paper) Pump-and-treat is a common technique for the remediation of contaminated aquifers. However, slow kinetic mass transfer at sites contaminated with organic compounds may reduce the efficiency of the pump-and-treat remediation. Although continuous pumping tends at first to remove high concentrations from an aquifer, it soon removes much lower concentrations due to slow mass transfer from immobile to mobile phases. Pulsed pumping, in which the pump is periodically turned off, has been suggested as a ...
