Non-wetting Additive as a Solution to Minimize the Corrosion of Refractory Castables Against Molten Aluminum
Non-wetting Additive as a Solution to Minimize the Corrosion of Refractory Castables Against Molten Aluminum
摘要
The ternary compound barium aluminosilicate BaAl2Si2O8, known as celsian, a non-wetting additive that increases the corrosion resistance of refractor） materials against molten aluminum, was incorporated into the matrix of a high-alumina low cement castable after its synthesis using barite and a low cost source of alumina and silica. This paper presents the influence of this phase on the wetting angle formed between liquid aluminum alloy and solid refractory castable surface.
