Ceramic foam filter

Ceramic foam filter is produced by special processes with fine ceramic material which can be used for

the filtration of molten steel, iron castings and non-ferrous alloy. The filter can effectively remove

non-metallic inclusions like slag and dross of molten metal. As a result, the pore, sand and dross hole

 could be reduced to a very low level and the surface quality, machining property and mechanical

property is improved. The filter can also reduce turbulence in the gating system and help to improve

the quality of castings. It's a typically ideal choice for producing superior quality castings.
