Chromium stabilization of tannery sludge by co-treatment with ladle furnace slag
Hazardous solid wastes may pose a serious risk to human health and to the environment, if not managed appropriately and disposed of safely. In this study, the effective stabilization of tannery sludge, a toxic industrial solid waste produced from the physico-chemical treatment of tannery wastewaters, was examined by the addition of ladle furnace slag (LFS), another industrial solid waste. Moreo...
متن کاملNumerical Study on Flow, Temperature, and Concentration Distribution Features of Combined Gas and Bottom-Electromagnetic Stirring in a Ladle
A novel method of combined argon gas stirring and bottom-rotating electromagnetic stirring in a ladle refining process is presented in this report. A three-dimensional numerical model was adopted to investigate its effect on improving flow field, eliminating temperature stratification, and homogenizing concentration distribution. The results show that the electromagnetic force has a tendency to...
متن کاملINVESTIGATION ON SLAG-REFRACTORY INTERACTION IN LADLE USING COMPUTATIONAL TECHNIQUES
Abstract: Thermodynamic computational packages MTDATA and FactSage have been used to carry out calculations on the variation with temperature of the phases precipitated on cooling in both oxidising and reducing conditions of a typical ladle slag composition, in the temperature range 1700 - 900°C. The current coverage of the databases associated with the computational packages is discussed i...
متن کاملImprovement of Cleanness in Melt of Tool Steel by Control of Gas Bubbles And Electromagnetic stirring in the ladle during vacuum treatment
The first part of the project is mainly about changing of slag compositions and see it affect on the inclusions in the ladle furnace. The second part of the project is to study the influence of stirring (EMGAS) on the large inclusions in the steel by changing stirring conditions. The project has done at Uddeholm AB, Hagfors. First, the scrap is melted in ARC furnace then moved to the ladle de-s...
