Developing Two New Tundish Plasters and Comparing with
In the continuous casting of steel the porous structure of tundish plaster with high-MgO content is commonly used. Destruction of this type of plaster is the result of silicate phases with low melting points that are created when slag containing SiO 2 and CaO penetrates into pores of plaster and reacts with periclase (MgO).
