Zirconia foam ceramic filter/piece/web:

The basic material of “DERGDS” zirconia foam ceramic filter is ZrO2. The endurable temperature of zirconia filtering web is about 1760℃ and it has extraordinary intensity and great high-temperature impact.

Parts of steel casts are extensively used where the great intensity and good stretch rate are required. So it is hypersensitive for the steel casts to cause the defects by the impurities. The outstanding characteristic of “DERGDS” can effectively eliminate the impurities that induce the quality defects of the products. These impurities are mainly composed of nonmetal particles, slag and the fragments of fire-retardant materials. And it can enhance the quality of the surface of the casts and mechanical performance and can reduce the proportion of wasters.

“DERGDS” filtering web can make the steel liquid equably fill the inside of the mold. While being filled, the melted metal trends to flow in disorder. Through the three-dimensional structure of “DERGDS” filtering web, the disordered flow turns out to be very stable. The stable flow can fill the inside perfectly and reduce the erosion caused by metal liquid impacting the inside of the mold and obviously decrease the proportion of wasters.

·having the obvious effect of filtering all kinds of steel, including carbon steel, stainless steel, co-based superalloy and ni-base superalloy, etc.

·made of pure zirconia and the temperature can achieve 1760℃ and the changes of the molding temperature for different types of steel is not sensitive.

·the excellent raw materials and the advanced production techniques guarantee that the filtering web has the stable tolerance of size.

Nonmetal impurities of the casts are the main factor that induces the defects of the casts. They will influence the brightness of the surfaces and mechanical processing performance and make the proportion of wasters larger. “DERGDS” foam ceramic filter products can eliminate the impurities and reduce the disordered flow in order to obtain a rapid and stable metal liquid flow that fills the mold and can enhance the quality of the casts.
