Ceramic foam filters
Arffil ceramic foam filters are characterized as high permeation rate, good strength and thermal shock resistance, stable quality and without loosing impurity in high temperature either in big size or small ppi products.
Advantages compared with traditional filtering materials:
Thermal and chemical stability in high temperatureücavoiding the chemical reaction with the filtered molten metal.
High porosity and good mechanical strength in elevate temperature due to its pure ceramic composite.
Full open cell without loosing ceramic particles or powders (snowing) during filtrating.
Low head loss, easy operation, energy save.
Make metal flow reposeful and avoid the sputtering and backset, this increases the surface quality of the cast, prevent the pore disfigurement and finally lower down the waster rate.
Box quantity depends on the filters's dimensions
Highly exothermic insulating sleeves
* highly exothermic insulating sleeves for feeder of pieces, melted in iron, steel and all the alloys of those metals, cast in sand and other systems. These sleeves provide good pieces, without porosity and without reaction of the metal with the sleeve.
Moulding mode:
Manually, pressure, blow explosion, impact.
Melting applications:
Steel (carbon steel, high and low alloy, stainless, hadfield)
Iron (malleable, nodular, grey, high and low alloy)
* highly insulating sleeves for feeder of pieces melted in iron, steel, copper, aluminium and all the alloys of these metals, cast in sand and other systems and specially for very low stainless steels in carbon. These sleeves provide good pieces, without porosity and without reaction of the metal with the sleeve.
