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 product is widely used in metallurgy, foundry metal melt filtration, using mullite (cordierite) and ceramic materials, high-quality high-density mesh straight holes to make our products with high thermal shock resistance and high fever casting temperature characteristics, straight-hole design ensures a balance between flow rate and intensity to effectively remove impurities and residue particles, so that casting mechanical properties, surface quality and product qualification rate increased substantially. 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. Significantly reduce the rate of casting scrap. Casting performance, increase the compressive sealing the casting to enhance the elongation and tensile strength, improve casting surface finish. Performance improvements casting molten metal flow, to increase the filling capacity and casting feeding ability. (2) The casting system design simplifies the pouring system design. Reducing the length of the horizontal runner to improve the casting process production rate. Casting process reduces machining time and tool damage, improved casting surface quality, its use can reduce waste 60-80%. Filter the user will receive years of Linklaters million yuan. Use and advantages of ceramic filter film is to eliminate casting defects, to obtain the best quality and the perfect casting purification functional elements. Can be used for casting the production of various types of liquid metal within the filter.
