Crucible protective coating
Graphite crucible is one of the indispensable tools in aluminum smelt-ing production. The temperature of aluminum smelting is mostly concen-trated between 700-800 ℃,and the oxidation weight loss of graphite crucible is particularly significant in this temperature range.BCC-30 is a water-based coating designed to protect crucibles, with a unique combina-tion of high-temperature adhesives that can firmly adhere the coating to a smooth graphite surface;The use of ultra-fine high-purity aluminum oxide powder can fill the surface gaps of graphite crucibles, making it difficult for aluminum liquid to immerse; In addition, high-purity Boron nitride is added,which not only protects the crucible and melt, but also has excellent demoulding effect.
