Product DescriptionAlumina ceramic foam filter is a trade
description of low-density foundry filters,which are designed for
filtration of aluminum and aluminum alloys.Ceramic foam filter
plate is produced basing on carrier with solid reticular structure
and combined organic foam pores. The producing procedure is as
below, put carrier into the thixotropic alumina slurry, adopt
square to center correcting automatic extrusion process, so that
slurry evenly deposits in foam skeleton of carrier, after drying
solidification, then carrier will turn into final product by
roasting formed under 1180 ºC high temperature.The filters are
placed into pre-developed chambers in inlet systems of the form or
in sprue cups.They are suitable mainly for chill casting and for
direct and indirect casting on a filter.Product Features1.High
porosity2.Superior dimensional tolerances3.Low loss of thermal
shock4.High mechanical strength at normal and high
temperature5.Large specific surface6.Good chemical
stability7.Excellent filtering functions of screen8.Excellent
filtering residua collection and absorption9.Beveled edges and
compressible gasket Product ParametersChemical
