    Theoretical and Experimental Study of the Influence of the Mg in Deoxidisation Al on the Non-Metallic Inclusions Formation in Steel

  • Original language description

    Theoretical and Experimental Study of the Influence of the Mg in Deoxidisation A1 on the Non-Metallic Inclusions Formation in Steel. There were done thermodynamic analyse of the formation of the inclusions on the spinel base in liquid steel. 106/04/0029.Inclusions of type MgO.Al2O3 rise at the deoxidisation of the steel by aluminium containing magnesium. Magnesium increases aluminium deoxidisation ability because rising MgO decreases A1203 activity. A12O3 and MgO.Al2O3 inclusions are solid, hardly float from the steel and can clog the CCM nozzles. There was verified experimentally that in system Al-Mg-Ca-O-Fe (under steel deoxidisation by aluminium and following calcium modification) rise inclusions, whose nucleus is formed by the solid spinel and around the nucleus precipitate liquid cover formed by calcium aluminates.

    Teoretické a experimentální ověření vlivu hořčíku v dezoxidačním hliníku na nekovové vměstky vznikající v oceli

  • Czech description

    V tekuté oceli byla provedena termodynamická analýza tvorby vměstků na bázi spinelu. 106/04/0029. Vměsky typu MgO.Al2O3 rostou při desoxidaci oceli granulovaným hliníkem s obsahem hořčíku. Hořčík zvyšuje schopnost desoxidovat ocel hliníkem, protože rostoucí MgO snižuje aktivitu Al2O3. Vměstky Al2O3 a MgO.Al2O3 jsou pevné, špatně se vyplavují z oceli a mohou ucpat výlevky. Bylo experimentálně ověřeno, že v systému Al-Mg-Ca-O-Fe (při desoxidaci oceli hliníkem s následnou modifikací vápníkem) vměstky rostou, jejíž jádra jsou tvořena tuhým spinelem a okolo pokrytá tekutým hlinitanem vápenatým.
