Abstract: The volume weight, compression properties and water absorption character of slag wool fiberboard were studied with sodium silicate as binder. The results show that: the sodium silicate binder can increase the volume weight of the fiberboard, improve the compression properties and water insulation of fiberboard. At the same time, the microscopic morphology of the slag wool fiberboard were observed through SEM, it can be gotten that the fiber is wrapped by sodium silicate binder, and a layer of effective adhesive films is formed on the fiber surface which makes the slag fiberboard have the higher stability at a high temperature.

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: To introduce the situation of removal phosphorus from steel slag at present, the existence of phosphorus in the steel slag was analyzed. The technical concept that steel slag was used as a sintering raw material in sintering process was proposed by the thermodynamic analysis on the base of adding ferrous manganese ore.The technology has reference value for making steel slag be the raw material of sintering and can control the content of phosphorus in the sintering to a certain extent.
