  1. 1. Secondary Steel Metallurgy Slag Design and MgO-C Refractory Implications : Theoretical and Practical Considerations

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Hellgren Simon; [2019]
    Keywords : MgO-C; CaO-SiO2-Al2O3-MgO; Slag Design; Refractory Wear;

    Abstract : MgO-C based refractory materials, often used in secondary steel making, are exposed to variouswear mechanisms in its application. The wear could be divided into oxidative, chemical andabrasive categories, all behaving differently and all being influenced by different factors. READ MORE
