Honeycomb Ceramic Filter also can be called Extruded Ceramic Filters or Molten Metal Cellular Filters, are widely used as molten metal filtration in metallurgical and foundry industries. This product has the characters of excellent resistance to thermal shock, high strength, high porosity and specific surface area. With its unique straight channel honeycomb designs, it can increase the specific surface area between molten metal and ceramic filter, thereby to improve its adsorpting and capturing tiny impurities ability, so as to get ride of non-metal impurity and gas, make the metal liquid steady, purify metal liquid. It can not only reduce casting cost, but also improve casting quality.
*As support of catalyst, ceramic honeycomb materials are typically used for purifying automotive emission, removing bad smell etc.
*As heat exchange media, ceramic honeycomb materials are mainly utilized in heat recovery unit of RTO's instead of ceramic saddles.
*As filtrate substrate, ceramic honeycomb materials are generally utilized in food processing, water treatment, environmental industry, metallurgical industry etc.
Shapes and sizes
The shapes include as follows: Round, square, triangular, sector, or to be customized etc.
The size include below: Standard type 150mm x 150mm x 300mm, 100mm x 100mm x 100mm, 100mm x 100mm x 150mm, other size can be manufactured according to customers' requirements.
*Good work strength under high temperature, good thermal shock resistance and melted metal inflow resistance
*High strength under room temperature, mechanic push resistance
*Obvious filter effect
*Ease the uneven inflow of casting, smooth the casting process, avoid surface defect
*Have a large and even melted inflow rate
*Good chemical stability, not affected by of melted meta, no change in its chemical compound
*Precise dimension and can be used in production line automatic filter mounting equipment
Series of products of new material honeycomb ceramics takes the key part in environment protecting industry, which includes industrial waste gas, waste water purified, rubbish burning etc., at the same time, it is the first choice for the material of heat exchanger, regenerator, Gas stove etc., which relates to environment protecting product. At melting metal liquid at ceramic hole eyes, in order to removing metal the refractory piece, alloy and melt the inclusion, such as dreg, etc. That melts of solution. The ceramic filter of honeycomb still plays a peculiar rectification role, can get steady and fast solution laminar flow, can prevent bubbles from entering, avoid the harmful effects that cause by the turbulance makes the metal oxidize and splash by the solution.
