FAQ Guide About Zirconia Ceramic Foam Filters
If you want to know anything else about Zirconia Ceramic Foam Filters, please contact us to leave your questions, professional foundry solutions are waiting for you.
Zirconia Ceramic Foam Filter is a phosphate-free, high melting point, It is characterized by high porosity and mechanochemical stability and excellent resistance to thermal shock and corrosion from molten steel.
Zirconia ceramic foam filter is a porous material with high-temperature properties. It is steadfast for filtering steel and alloy steel temperature resistant up to 1700°C.
In the process of transportation & use of the filter plate, it must withstand the impact of a certain pressure from the outside, so the index of compressive strength is also introduced in the standard as one of the bases for measuring the quality of the filter plate.
