honeycomb ceramic foundry filters
   
 
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 non-metal impurities.
 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 requirements.
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
