An anti-wetting agent additive of a refractory aluminum alloy furnace lining material, the additive-containing binder, the refractory concrete containing the binder, and the use of the additive

摘要

Anti-wetting agent additive of a refractory aluminum alloy melting furnace lining material, which is suitable for forming a corrosion protection layer on the surface of the aluminum alloy melting furnace lining material by contact reaction of the additive with melt pool components, characterized in that the additive is free of calcium fluoride, does not decompose until at least 1450 ° C. a) at least one fluoride from the group of the following fluorides: aluminum fluoride, barium fluoride, strontium fluoride, and b) has a synthetically produced barium sulfate.
