Key words:
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.
Key words:
BSC-20 is a water-based ultra-high temperature release agent, which is different from Boron nitride coating (temperature resistance is about 1000 ℃). The product can meet a maximum temperature of more than 1800 ℃, and has good lubrication effect and high temperature stability. It is suitable for the melting and casting process of steel, copper alloy and other metal materials. It can be painted on the surface of launders, crucibles and other materials, effectively preventing the adhesion of molten metal and refractory materials under high temperature,and improving production efficiency, At the same time, it does not cause pollution to the product and the environment.
