Fluid flow in the mold region of the continuous slab caster at Panzhihua Steel is investigated with 0.6-scale water model experiments, industrial measurements, and numerical simulations. In the water model, multiphase fluid flow in the submerged entry nozzle (SEN) and the mold with gas injection is investigated. Top surface level fluctuations, pressure at the jet impingement point, and the flow...

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...

In order to investigate the influence of SiC on composition and structure mixed slag (blast-furnace slag: steel = 1:9), chemical composition, equilibrium-phase microscopic morphological characteristics elemental distribution in region SiC-reagent-tempered samples were analyzed by X-ray diffractometer (XRD), FactSage7.1 thermodynamic analysis software, scanning electron microscope, energy spectr...

is known that metal which is produced by the method of electroslag remelting (ESR) has service properties superior to those of metal made by open refining and casting. This can be attributed to the better conditions which exist for refining in the specially chosen slag and for the crystallization of the metal in the case of ESR. However, the need for a two-stage metallurgical conversion (essent...

This paper describes a review of the potential use of High Strength Incorporating Ground Granulated Blast Furnace Slag and Steel Fiber Reinforced Concrete used in construction industry to improve the structural strength and reduce steel reinforcements requirements. Blast furnace slag (GGBS) has been used as a supplementary material along with the cement. It helps in increasing the durability an...

This paper demonstrates the use of a new model consisting of a genetic algorithm in combination with thermodynamic calculations and analytical process models to minimize the processing time during a vacuum degassing treatment of liquid steel. The model sets multiple simultaneous targets for final S, N, O, Si and Al levels and uses the total slag mass, the slag composition, the steel composition...

the use of various slags as by-products of steel industry is well established in civil engineering applications. however, the use of bos slag in the area of soil stabilization has not been fully researched and developed despite having similar chemical composition and mineralogy to that of portland cement. this paper reports on efforts to extend the use of bos slag to soil stabilization by deter...

We study the formation of singularities for the mean curvature flow of monotone Lagrangians in C. More precisely, we show that if singularities happen before a critical time then the tangent flow can be decomposed into a finite union of area-minimizing Lagrangian cones (Slag cones). When n = 2, we can improve this result by showing that connected components of the rescaled flow converge to an a...

have low base saturation and pH values with high A pot experiment was carried out to study the concentrations d soluble aluminium and ]OW conceneffect of carbonate and various silica-contrations of silica. A pot experiment was therefore taining materials on cane growth and to compare designed to test the effect of silica on soils from this the relative efficiencies of calcium carbonate and area...

In this study, unconfined compression tests have been conducted to investigate the impacts of copper slag on mechanical characteristics for stabilized cement and un-stabilized soil. Dozens of specimens were prepared at four percentages of cement (i.e. 0%, 2%, 4% and 6%) and five percentages of copper slag (i.e. 0%, 5%, 10%, 15% and 20%) by weight of dry soil. The samples compacted into a cylind...
