Figure 2: Slag buildup in the inductor and throat of a vertical channel furnace (gray shaded area) 3 (a) (b) Figure 3: Circulation and metal flow (shown by the arrows) in a (3a) single loop inductor and (3b) double loop inductor. Figure 3 illustrates circulation and metal flow through both single and double loop inductors. Not only can buildup occur in the inductor loop and throat areas, but ...
amounts of stainless steel slag were landfilled or stored in slag yards as hazardous solid waste (waste egory in China: HW21), which not only occupied a large amount of land but also polluted the natural environment. Previous studies[2] have shown that trivalent chromium in unstable phases among the stainless steel slag could be converted into highly toxic hexavalent chromium in air and ...
Figure 1 displays a Richardson diagram for selected compounds of stainless steel slags, calculated with thermodynamic data from HSC 8. It can be seen that from a thermodynamic point of view the reduction of chromium oxide is possible with manganese, silicon, aluminum and carbon at a temperature of more than 1200 °C. However, the Gibbs free energy difference of chromium oxide and manganese ...
· Disintegration of stainless‐steel slag during cooling is caused by the β→γ transformation of dicalcium silie (2CaOSiO 2 or C 2 S). It is well established that disintegration can be avoided by borate additions, which are commonly believed to stabilize the high‐temperature polymorphs by forming a solid solution with C 2 S. In this study, the borate distributions in slowly cooled ...
Steel Slags and Steel SlagAsphalt Paving Mixes A ... using the standard Proctor method and stainless steel molds with perforated base plates to allow for moisture movement during the immersion period. The specimens were then immersed in the water bath and maintained at 71 °C ± 2°C, and the vertical expansion with time was recorded daily for 2 weeks. Steel slag~asphalt briquettes with 8 to ...
Austenitic stainless steel is used in this example what is recommended for use in aggresive environments. Dimensioning of steel plates, stiffened and unstiffened, according to Eurocode is carried out according to EN 199317, which refers to plates loaded out of their plane. Within the first part of the analysis dimensioning is performed according to Eurocode 3. The second part of the paper ...

Stainless steel wire with a lay of 1 x 19 has the greatest elastic modulus and will take up the same load with less extension than equivalent wires with other lays. 9. Sharp ends of wires at terminations and swages need to be removed for the safety of children and other people. No wire end should protrude more than half the diameter of the wire from the swage or termination fitting. Table ...
stainless steel in South Africa. Dimensional analysis was done to correlate mathematically the dispersed phase holdup with the operating conditions and the modified Froude number. The overall expression of the holdup revealed that the dispersed slag phase decreased with the vertical distance from the original interface between the liquid phases. The dispersed phase also decreased with the ...

Results on liquid steel Figure 3 shows the results obtained on liquid steel. The red solid line represents the temperature of the liquid steel, corresponding with the second yaxis on the right. The vertical positions of the dots indie the meniscus level as measured by the radar. The colour of the data point denotes the relative strength of the radar signal. At time 13:48, the induction ...
Figure 1 pictures a few of the most important ones. Vertical machines are used to cast aluminum and a few other metals for special appliions. Curved machines are used for the majority of steel casting and require bending and / or unbending of the solidifying strand. Horizontal casting features a shorter building and is used occasionally for ...
