Product Description

Product Description

Aluminum Oxide Filter, Alumina Porous Ceramic Foam Filter for Casting

Alumina 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.
