Ceramic Foam Filter Molten Metal Filtration

All surfaces including the cut sides have the desirable open pore structure of true ceramic foam.

Ceramic foam filter molten metal filtration.

When pyrotek launched in 1956 its primary product was a glass cloth filter for molten aluminium. The cellular design also provides an engineered balance between flow rate and strength. These filters are precision cut after firing to the tightest dimensional tolerances in the world. Introduced by selee in the mid 1970s and redeveloped with cs x the selee ceramic foam filter continues to be the standard for aluminum filtration in cast houses all over the world.

Extruded ceramic filters can effectively capture inclusions and reduce turbulence of the molten metal mullite based ceramic material could withstand heavy pouring thermal shock and extreme pouring temperature. Zirconia ceramic foam filters are determined for filtering of steel and steel alloys up to the. Temperature of 1700 c. Molten metal filtration and distribution during aluminum casting it is common practice to use the filter bag made from the heat resistant glass fiber fabric in order to filter the molten aluminiuim that is being poured through a spout and to distribute it all over the mold surface.

Filters are recommended especially for high quality grades of alloys. Inline filters for casthouse applications can take many forms and are usually categorized into multiple use filter boxes or single use disposable filters such as trough socks and ceramic foam filters cff. The ceramic foam filter cff of selee structure was the first cost effective media to remove non metallic inclusions from molten aluminum. Disa automatic moulding line disa mouding line horizontal and vertical extruded ceramic filter pressed ceramic filter or ceramic foam filter used for molten metal filtration by inserting into filter seat.

Alumina ceramic foam filter is mainly for the filtration of molten aluminium and alloys in foundries and. With the excellent resistance to attack and corrosion from molten aluminum the filter can effectively remove inclusions reduce trapped gas and provide laminar flow and then the filtered metal is significantly cleaner. The superior dimensional tolerances of selee filters for iron filtration are recognizable at first glance. Using cost effective metal filtration cup filters simple but very effective to replace ceramic foam filter.

Fibrete is proved to be very effective for molten metal filtration in almost all types of aluminium foundries including sand permanent mold shell die casting and investment castings and it will be optimized choice to improve casting quality by using the fiberglass fabric mesh filters. Zirconia ceramic foam filter application.
