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...

Ladle refractories were subject to repeated chemical erosion and physical scouring by various hot fluids such as steel slag, liquid steel, argon oxygen. Firstly, the heat transfer model of ladle wall was established, refractory under different corrosion conditions analyzed. The relationship between residual thickness lining temperature field outer surface established. Secondly, a set infrared t...

Abstract Fluorspar (CaF 2 ) is commonly used to control the fluidity of slag in ladle-refining steel. However, because it desirable reduce CaF consumption its environmental impacts, industrial waste material such as white mud (WM) was investigated a potential substitute for fluorspar. Steel sample (Fe-0.3C-0.9Mn-0.3Si-0.03Al-0.05S, mass pct) melted high-frequency induction furnace, followed by ...

A method of contactless identification is proposed for steel ladles to eliminate manual inputs that negatively affect the monitoring system ladles. It an RFID (Radio Frequency Identification) based on principle radio data transmission between sensor and a moving object (in our case, ladle), which equipped with so-called transponder (RFID tag). The tag was part ladle; it placed its shell, reachi...

A series of industrial trials argon injection into ladle shroud (AIILS) with different argon-blowing rates were conducted in this study. Firstly, bubbles actual liquid steel the tundish captured by method “cold plate dipping” and characterized microscope examination. detailed investigation on three-dimension morphology was carried out using computerized tomography (ICT). Then, two-phase flow ga...

To investigate the gas agitation characteristics of side blowing, fluid flow and mixing phenomenon in a 1:3 scale model ladle 150 t industrial gas-stirred with bottom plugs were studied by using physical numerical modelings together. Side blowing enhanced horizontal water ladle. Compared that is close to more than two increases average velocity water, which represents power, improves uniformity...
