Abstract: In order to study the application of fluidized bed process for the gas quenching steel slag(GQSS) slag-iron separation, according to the principles of fluidized bed material separation, based on the all GQSS, this paper researches the influence law of fluidization characteristics and the fluidization performance of GQSS after adding 20% (calculated by volume) iron grains. The experiment uses single hood fluidized bed as experiment device, studies the GQSS and iron grains of critical fluidization and slugging fluidization of other characteristics in the fluidization process, and determinates the packing density in interior and exterior of the tube. The results show that: when the material is all GQSS, the appropriate fluidization thickness of material layer is 300~400mm ; after adding 20% iron grains in the tube, the appropriate fluidization thickness of material layer is 350~400mm. The results of this paper on GQSS slag-iron separation have important theoretical significance.

Abstract: Based on electromagnetic theory, a billet model electromagnetic continuous casting of physical and mathematical were established. The three-dimensional mold for billet electromagnetic field was calculated by finite element method of ANSYS three-dimensional numerical simulation. Then the distribution of the electromagnetic field inside the crystal was gotten. At the same time, the influence of the power frequency and current strength on the intensity and distribution of the magnetic field were simulated. The result shows that the maximum of the electromagnetic flux density lies in the center of induction coil (steel surface in the center of the coil), and the magnetic flux density gradually reduces along the casting direction; the magnetic flux density increases while the power frequency is increasing; the magnetic flux density increases with the increasing of the current intensity.
