VUKOPOR^® HT ceramic foam filters are determined for filtering of steel and steel alloys up to the temperature of 1680 °C. Filters are recommended especially for high quality grades of alloys.

The ZrO₂ based filters are intended for filtering steels, in particular highly alloyed steels, where high reliability and chemical purity is requested – aerospace and IGT markets. High mechanical strength is their great advantage, because it enables their application for filtration systems of heavy and massive castings – filtration carousels and grates.

VUKOPOR^® HT filters can be used in gating systems by different ways. It may be used directly in the gating system in special filter prints, inside the ceramic shell or ceramic cups in lost wax process.

It is necessary to take into consideration high thermal capacity of zirconium filters and their suitability for different alloys filtration at their usage in exothermic sleeves or pouring basins.

The perfect stability and high mechanical resistance allow the utilization of filters inside the filtration carousels and filtration grates and thus filtering of heavy castings of several dozens of tons is enabled.
