Ceramic honeycomb filters are widely used in metallurgy, metal melt filtration of the foundry industry, mullite (cordierite), ceramic materials, high-quality high-density straight hole mesh, so that the product has a high thermal shock resistance and high temperature the characteristics of straight-hole design to ensure the balance between the flow and the strength to remove impurities and slag particles, so that the mechanical properties of castings and greatly improve the surface quality and rate of qualified products.
Honeycomb ceramic materials with the natural ability of chemical adsorption (affinity) oxides, and adsorption on the inner wall of the hole in the liquid metal impurities (particles smaller than the hole size) to improve the filtering effect; advanced extrusion production has a unique square and triangle design process, so that ceramic filters, it increases the contact area with ceramic filters adsorption and the ability to capture small impurities than the non-extruded filters filter good effect, stable liquid metal; casting speed and continuity, reduce casting scrap rate and improve the mechanical properties of castings and prolong life.
Filter out the inclusions in the castings; reduce the gas in the casting, to reduce the degree of turbulence in the metal flow filling, reducing the casting surface defects. Significantly reduce casting scrap rate. The increase in casting performance of compression sealing of castings, and enhance the elongation and tensile strength, and improve the surface finish of the castings. Casting performance to improve the fluidity of the molten metal, to increase the filling capacity of the casting and feeding ability.
The gating system design is simplified. Reduce the length of the runner, and improve the casting process yield. Casting process to reduce processing time and tool damage, and improve its use of castings machined surface quality can reduce waste by 60-80%. Filters the user will receive tens of millions of dollars profit. The uses and advantages of the ceramic honeycomb filters eliminate casting defects, the quality of perfect casting purification of functional elements. Filter can be used for various type of liquid metal in the casting production.
(1) Have a very high high-temperature strength, thermal shock resistance and resistance to metal flow impact the ability. No dregs or rupture phenomenon at work to ensure the quality of the filtration of molten metal.
(2) The ability to mechanical shock. No broken or damaged in use and transport, will greatly facilitate the use of filters of the operation.
(3) Has a very significant filtering effect. Is much higher than the filtering effect of the fiber filter. Significant filtering effect.
(4) Can effectively reduce the turbulence of the liquid metal pouring, filling gentle, to avoid casting surface defects.
(5) Metal flow rate, and the flow rate stability (as distinct from the flow rate of the ceramic foam filters with to capture the increase in the number of inclusions decreased). Even if mixed with the matter content in the molten metal, the normal use will not cause the clogging of filters.
(6) With high chemical stability, not affected by the pH of the liquid metal does not change the chemical composition of the liquid metal.
(7) Have a very high dimensional accuracy, and can be used to automatically place in the production line of filters.
(8) Clearly superior to the use of performance cellular ceramic filters fiber filters, fiber filters in the filter effect, reduce the role of the turbulent flow of liquid metal, ceramic filters are not as good as high-temperature strength and other properties. The ceramic filter is the filter casting manufacturers in terms of practicality, reliability, quality and price considerations, chosen to eliminate the defects in the casting.
Can be Mullite, cordierite, alumina, silicon carbide.
