What is Zirconia Ceramic Foam Filter?

The basic material of zirconia ceramic foam filter is ZrO2.

The heat resistance temperature higher than about 1760℃, and it has very high strength and excellent high-temperature impact resistance.

What is application of Zirconia filter?

Zirconia Ceramic Foam Filters are used for filtration of all types of steel like unalloyed, low alloyed, stainless and high-alloyed.

Filters are recommended especially for high quality grades of alloys. 

Why is Zirconia filter used for steel casting?

Cast steel parts are widely used in aspects that require high strength and elongation requirements. Therefore, cast steel parts are very sensitive to defects caused by impurities.

The heat resistance temperature of zirconia ceramic foam filter is higher than about 1760℃, and it has very high strength and excellent high-temperature impact resistance.

The excellent characteristics of zirconia ceramic foam filter can effectively remove impurities that ultimately lead to product quality defects.

The impurities mainly consist of non-metallic particles, slag, and refractory material fragments.

It improves the surface quality and mechanical properties of the casting parts, reduces the scrap rate. 

What is working principle of zirconia filter?

Zirconia ceramic foam filter can make the molten steel fill the cavity more uniformly.

During pouring, the molten metal has a higher tendency for turbulence, and the turbulence after passing through the three-dimensional pore structure of the zirconia foam ceramic filter is ultimately converted into a very stable laminar flow.

The laminar flow has better filling properties for the cavity, thereby reducing the impact and corrosion of the molten metal solution on the casting cavity and significantly reducing the scrap rate.
