Ceramic Filter
Ceramic Filter with mullite-based materials, using straight-hole parallel to straight-channel, multi-pass design to ensure that the product of high strength and thermal shock performance, while ensuring casting pouring time, the use of ceramic filter films, performance, while ensuring casting pouring time, the use of ceramic filter films, of metal materials can be absorbed to reduce the appearance of pores inclusions to improve casting quality and reduce the after-processing costs for steel, iron, alloy steel, aluminum, copper foundry industry.
The use of ceramic filter chip has the following aspects of filtering efficiency:
1) The casting structure of inclusions in the casting filter to reduce the casting of the gas, reduce the metal flow during mold filling turbulence levels, reducing the casting surface defects.
(2) The casting system design simplifies the pouring system design. Reducing the length of the horizontal runner to improve the casting process production rate.
