China Thermal Shock Resistant Honeycomb Ceramic Filter for Metallurgy

Honeycomb Ceramic Filter has the characteristics: Larger specific surface, high mechanical strength, and perfect heat-resistance performance. It can make the following result through filter: Purify metal liquid and get ride of non- metal impurity and gas. Make the filling type of the metal liquid steady and reduce the swirl. Simplify the pouring system and improve the producing rate. Reduce the air vent of castings and optimize and thin out metal organization. Improve surface quality of castings and mechanical performance. Reduce the rejection rate of castings, reduce the surplus of processing, raise the life span of the cutter and reduce casting cost.
base on the case studying of domestic and international cast field in recent years, our factory adjust the prescription and innovate the technique to produce filters products series with different appearance specifications, wall thickness, hole type and aperture.
Cordierite, Mullite, Zircon mullite, Zirconia-corundum filters for the highest temperature 1350 Degree C, 1500 Degree C, 1580 Degree C and 1650 Degree C.
Good thermal shock properties, not blowdown, not be collapsed
Uniform round hole make when metal liquid go through, small eddy will not be produce, more conducive to change metal liquid from laminar to turbulence.
Accurate extrusion die make product quality extremely stable and consistency.
The same appearance ceramic filters, the openings rate of square hole's is exceeding 10% than round hole's.
