The inner contact or wear lining is exposed to the highest temperature and is in direct contact with the furnace contents e.g. molten metal slag glass corrosive gases and fluidized particles. The inner lining must therefore be resistant to chemical and erosive attack and consequently it is the best quality refractory with the lowest

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).
