Non stick aluminum refractory material, also known as aluminum melting furnace non stick aluminum refractory material, is a non stick aluminum refractory material developed for the aluminum and aluminum alloy industry, using high-purity mullite, andalusite, sillimanite, steel fiber, and other aggregates, combined with various binders such as pure calcium aluminate cement and ultrafine powder.
Physical and chemical indicators of aluminum free casting materials for aluminum melting furnaces:
Due to the combination of high-purity raw materials and ultrafine powders, this material has the characteristics of non aluminum, high bulk density, density, high * * *, anti peeling, high strength, erosion resistance, * * * pores, volume stability, good thermal shock stability, and anti permeability. By adding an appropriate amount of "non wetting agents" (such as high-purity chromium oxide, composite barium salt, composite zinc salt, etc.), it can significantly reduce the wettability of aluminum, alloys, and slag melt on refractory materials, improve the corrosion resistance, erosion resistance, and non aluminum and slag function of refractory materials to aluminum liquid containing salt, flux, and other chemical components, that is, prevent aluminum, alloys, and slag from infiltrating into refractory materials. Materials to extend the lifespan of the furnace lining.
