Ceramic honeycomb filter is mainly used in metallurgy, foundry industry, the product features in a large surface area, high mechanical strength, good thermal shock resistance. In the casting of liquid metal, honeycomb ceramic filter can filter out impurities, reduce casting porosity, improve casting quality, as a result: casting cost is reduced and labour productivity is improved.When the molten liquid metal passes through the ceramic honeycomb channel, the debris, the slag and other inclusions are removed. Ceramic honeycomb filter improves the quality of molten metal flow. A stable and fast laminar molten metal flow prevents air from getting into the molten metal flow, molten metal getting oxidized and splashing out.

Experiments show that, after using honeycomb ceramic filters, the molten aluminium mobility is improves by about 25 to 30%; the casting rejection rate is reduced by 85%; the casting strength is increased by 10 to 20%; the mobility of molten iron is increased by 10 to 15%; the pore defects in casting is significantly reduced; the casting machining performance is greatly improved. Because the impurities are filtered out, the hard point in casting is also eliminated. Currently, ceramic honeycomb ceramic filter has been applied to aerospace, automotive, machinery and many other casting areas, to improve the reliability and performance casting.

• Base on the case studying in recent years, the prescription and innovate the technique are adjusted to produce ceramic honeycomb filters with different specifications:Cordierite, Mullite, Zirconia mullite, Zirconia corundum filters for the highest temperature 1350 ⁰C, 1500 ⁰C, 1580 ⁰C and 1650 ⁰C
• Good thermal shock properties
• Uniform round hole, avoid small eddy and turbulence molten metal flow when metal liquid passing through
• Accurate extrusion die makes the quality of ceramic honeycomb filter extremely stable and consistency
