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
Can be Mullite, cordierite, alumina, silicon carbide.
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.
The main advantage of the product are:
(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
(3) Has a very significant filtering effect. Is much higher than
the filtering effect of the fiber filter. Significant filtering
(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
(7) Have a very high dimensional accuracy, and can be used to
automatically place in the production line of filters.
