We can supply ceramic foam filters are as follows: 1.Silicon carbide ( SiC) is used as a distinctive element in the refractory mixture material to make foam filters. Gray in color, foam filter is a strong and durable foam filter, which can be used to purge and filter solution of ductile iron casting, grey iron and other iron casting. 2. Zirconia Ceramic Foam Filter is applied to purge and filter solution of steel high temperature metal such as steel alloy stainless steel etc.Typical application of zirconia ceramic foam filter is for in-mold, tundish, pouring cup or baffle-type filtration. 3. Alumina Ceramic Foam Filter is applied to purge and filter solution of aluminium and aluminium alloys. White in color alumina foam filter is made from high purity alumina (AI2O3). It has excellent ability to resist high thermal shock while maintaining efficient removal of impurities with continuous and thorough filtration. Advantage of Ceramic Foam Filters 1.Simplified and shorten gating system,increasing yield. 2.High strength without loose ceramic particles or powder 3.Remove tiny slag effectively and purify molten metal. 4.Three dimensional connected mesh structure and high porosity 5. Well-distributed molten metal and improve performance. 6. Quiet laminar flow of molten metal. 7.Smaller particles are captured on the filter cake created by the larger particles , finer particles are captured within the pores in the filter. Principle Of Using Filter: AcA Ac Set the filters as close as possible of the casting. AcA Ac Use simple gating system without dirt trap ( improve yield). AcA Ac The working area of filter should be 4AcA A 6 times of the section of chocked flow in gating system to make sure that the pouring speed is not affected. AcA Ac Select the proper filters according to types of metal and pouring temperature. AcA Ac The higher porosity, the better filtration.

Stainless steel ,Carbon steel and large cast iron . How To Choose Porosity Of Filter: a c The higher porosity, the better filtration. But too high porosity leads to low speed rate of metal. This is especially important for SG iron.Usually our recommendation are as belowi a c 10ppia for ductile iron, big grey iron, steel casting. a c 20ppia for grey iron, malleable cast-iron,non ferrous alloy casting. a c 30ppia for grey and malleable cast-iron, non ferrous alloy casting. How To Set Filter: The ceramic foam filter can be used in the filtration chamber of a gating system as well as for direct pouring on the filter. Filter is usually set above or below the sprue, runner, in pouring cup.
