Ceramic Foam Filters 10 20 30 40 50 PPI Round Zirconium Oxide Foam Filter
Product Description
Zirconia Ceramic Foam Filters:
Excellent performance: Suitable for purification and filtration of stainless steel, carbon steel, copper castings and other high temperature alloy solutions below 1700C. Can filter non-metal slag inclusions and slags as small as micrometers, making the surface of steel castings smoother and reducing machining losses; the filter can make the molten steel fill the cavity more uniformly, and the molten metal has a higher turbulence during pouring tendency, the turbulent flowing through the three-dimensional pore structure is finally converted into a very stable laminar flow. Laminar flow fills the cavity better, which reduces the impact corrosion of the metal solution on the casting cavity, and significantly reduces the reject rate, reduces production costs, and improves labor productivity.
