Bonding ability of ladle slags
Original language description
Both Energetic and Metallurgy industry produce large amount of fine grain waste products. Thanks to their properties and composition these waste substances can be recycled back in their original production, where they become from. A typical characteristics of discussed materials is their fineness, and thus their difficult manipulativeness. For their successful regeneration in an original production, it is necessary to densify them into bigger pieces like briquettes or pellets. The research described below in this article focusing on investigation of bonding system, which would be possible to use for compactation of chosen waste products. Usage of ladle slags as a bonding system is not very well explored area. It was found out, that for example ladle slags play a good role as a bonding compound in process of briquette making with addition of fine grain metal bearing wastes. A compressive strength of prepared briquettes was of value 46 MPa after water hydration and 125 MPa in the case of alkali activation. An iron content was changeable depending on amount of specific used raw material. Some tested materials used in this project contain more than 90 wt. % of iron oxides, so it can be concluded, they are based on them. Any content of conventional binder participates on composition of prepared briquettes. Chemical and mineralogical composition of studied raw materials and briquettes was identified by XRFS, XRD methods. A calorimetric measurement of waste hydration heat and determination of cold compressive strength after 2, 7 and 28 days were also applied.
