High Temperature Honeycomb Ceramic Filter Ceramic Honeycomb Filter for Foundry

Ceramic honeycomb filter 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.

By using Al2O3, it independently developed cellular filters with pore density of 400 pores per square inches, compressive strength >20mPa, porosity > 20%. The shape of such filters include spherical, polygonal and mesh partition. Due to the strong corrosion-resistant property, high adsorption rate, no fall-off andenhanced durability, these type of filters have been favored by customers from Europe and the United States for years, using for the carrier of desulfurization and denitrification catalyst in petrochemical industry.

Materials: Mullite, cordierite ceramics, alumina, etc

Applications:
*As support of catalyst, ceramic honeycomb materials are typically used for purifying automotive emission, removing bad smell etc
*As heat exchange media, ceramic honeycomb materials are mainly utilized in heat recovery unit of RTO's instead of ceramic saddles
*As filtrate substrate, ceramic honeycomb materials are generally utilized in food processing, water treatment, environmental industry, metallurgical industry etc

Features:
*Purifying the metal liquid, absorbing the oxide and filtering the non-metal impurities
*Making the metal liquid flowing at stable speed, reducing the vortex and reducing the bubbles in the cast part
*Equalizing the phase structure and prolonging the tools lifetime
*Improving the cast part surface performance and improving the density of the cast part
