TYPE: Silicon carbide ceramic foam filter (Sic) Alumina ceramic foam filter Zirconia ceramic foam filter 1. Silicon carbide ceramic foam filter work at 1500 centigrade degree, apply for iron, copper and copper alloy foundry. 2. Alumina ceramic foam filterwork at 1100 centigrade degree, apply for aluminium foundry. 3. Zirconia ceramic foam filterwork at 1700 centigrade degree, apply for steel, stainless steel foundry. 4. Magnesia ceramic foam filter work at 1700 centigrade degree, apply for magnesia foundry specially. Ceramic foam filter is been made by specific procedures and have peculiar bone-frame holes just like the shape of foam(Called three-dimensional connected channel) and myriad eyelets which only been found in big times microscope. Compare to similar ones, our products have many advantages as below: --Stable chemical composition --Excellent strength --Resistant to high temperature --Calm down of the turbulent flow of metal nicely --big m2/m3 --Superior dimensional tolerances: +0/-2.5 Suggestions: A. Control the melting point satisfactorily. Especially high temperature will destroy it's function. B. Suitable PPI for different casting materials. C. Use the maximum temperature as soon as possibly. D. The pouring highness don't exceed 20cm commonly, and metal liquid don't touch the filtration directly.
