Honeycomb Ceramic

At melting metal liquid at ceramic hole eyes, in order to removing metal the refractory piece, alloy and melt the inclusion, such as dreg, etc. That melts of solution. The ceramic filter of honeycomb still plays a peculiar rectification role, can get steady and fast solution laminar flow, can prevent bubbles from entering, avoid the harmful effects that cause by the turbulance makes the metal oxidize and splash by the solution.Through the experiment, the aluminium alloy solution filtered by the honeycomb pottery, mobility improves by about 25 - 30%, casting than spending honeycomb ceramic province of filter low 85%ses, adopt honeycomb after the ceramic filter by rejection rate, the intensity of the casting improves by 10 - 20%, the mobility of the molten iron improves by 10 - 15%, has reduced hole eyes types defects of the casting, have reduced the rejection rate of the casting apparently. It filters impurity of shedding dispel casting hard a bit, improve casting processing characteristics greatly. At present, ceramic filters have already begun to be applied to a lot of casting fields in the honeycomb, in order to improve the dependability of casting performance and yield of the casting.
