Physical properties of molten slag such as viscosity, density and surface tension have a significant influence on the slag splashing process in an oxygen steelmaking converter. Particularly, viscosity determines the shear forces that rule droplets formation. Besides, stirring of the molten slag bath strongly depends on this property. In this work, the influence of viscosity on the efficiency of...

many researchers have reported positive effects of converter sludge and slag, two by-products in isfahan iron melting factory. in this work, the optimum rate of application and the availability of some essential elements (for plant growth) in the converter sludge and slag for corn were investigated. the converter sludge contains about 64% fe іі and ііі oxides and some other essential elements f...

Some variables that influence the slag splashing phenomenon in an oxygen steelmaking converter are numerically analyzed in this work. The effect of lance height, jet velocity, jet exit angle and slag viscosity on the washing and ejection mechanisms of slag splashing is studied in this work employing twodimensional transient computational fluid dynamics simulations. A parameter here called avera...

C. X. Li, H. Li, H. Lu, W. W. Mao: State key laboratory of advanced Metallurgy, University of Science and Technology Beijing, China This work examined phosphorus enrichment in different micro areas of the earlier slag and the final slag in converter double-slag technology. The results show that: phosphorus has high enrichment in the micro-area the basictity of which is between 2 to 2,5; the pho...

An important problem in metallurgy of iron and steel is management of hydrated, fine-grained, iron-bearing waste which can be formed as a result of gas scrubbing. The article presents a model of application of converter slurry in a closed-circuit flow system. The correct preparation of slag, namely briquetting with defined additives, allows for application of such slag in the steel-making proce...
