Ceramic honeycomb Filters slice for the metal melting now are
extensively applied to the metallurgic plants of casting/foundry,
for example,steel, iron, copper and aluminum, etc. Because of its
high mechanical intensity and heat-resistance, it is used to get
rid of the metal impurity, refractory scrap, solid refractory
alloy, sinter, in the molten metal liquid when casting the
products, so as to reduce the air vent of casting, improve the
quality of casting and also reduce the casting cost.
The honeycomb ceramic can be used as filter applied in metallurgy
and foundry industries, such product has below features:
1.Purifying the metal liquid, absorbing the oxide and filtering the
2.Making the metal liquid flowing at stable speed, reducing the
vortex and reducing the bubbles in the cast part.
3.Equalizing the phase structure and prolonging the tools lifetime.
4.Improving the cast part surface performance and improving the
density of the cast part.
Short summary of the advantages provided by casting filters:
in applications of light metal, grey cast and ductile iron
vermicular iron and other casting processes with highest
control, direct and filter the molten metal flow
available in cell densities of 50 300 CPSI
provides a free cross-section of 55 to 75 %.
removes dross,slag, and other impurities from the melt
efficiently accumulates and removes slag during the casting process
reduces or eliminates turbulences in the metal flow
