Honeycomb Pottery Filters

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.

Melting select any materials for use with honeycomb pottery by metal liquid filter, and honeycomb ceramic unit hole eyes number, wall thick, appearance size, etc. S, should be according to needing to filter the kind of the metal liquid with choosing defining. Select for use heat-resisting to assault sex, heat resistance high titanium sour aluminiums and come stone come and make metal spend the ceramic honeycomb by filter by quality pottery relatively generally.

A lot of developed countries, develop and use the ceramic packing of honeycomb in a lot of fields of alreadying processed in the chemical industry, encircling, petroleum etc, separates the result, has shown the considerable development prospect after receiving very good biography quality.
