The max. pore sizes-8ppi of zirconia ceramic foam filter

For Iron liquid filtration, zirconia ceramic foam filter is one of the best choice.(SIC is also best choice.)

PPI is the key point that decide if ceramic filter is availble or not. Because suitable ppi can ensure molten iron flow through them into ceramic molds quick enough, then make the perfect casts.

For now, the max. pore sizes of zirconia ceramic foam filter we can do is 8ppi.

Zirconia ceramic foam filters are the best choice for filtering steel and steel alloys up to the temperature of 1700℃. Filters are recommended especially for high quality grades of alloys.

Application: For the filtration of molten steel and alloy, large scale iron casting

Functions:

● Reduction in inclusion levels

● Good filtration capacity

● Ideal for the filtration of high alloyed steel

● High efficiency

● Filters can be preheated for investment casting application
