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
● 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
Refractory Reticulated Structure Zirconia Ceramic Foam Filters are the best choice for filtering of determined for filtering of steel and steel alloys up to the temperature of 1700℃. Filters are recommended especially for high quality grades of alloys.
It is weaved by high silica fiberglass yarn and coated with special refractory coating. It can effectively remove slag, refractory particles and non-metallic inclusions from molten metals. Made from specially treated silica yarns, the thick type silica mesh filters are capable of withstanding pouring temperature up to 1620℃.
