Honeycomb Ceramic Filter:
Honeycomb ceramic filter plate are widely used in metallurgy and casting industry for the filter of melted metal. Use mullite, cordierite, as its material and quality high density channel have endowed the products with good heat compression resistance and high casting temperature resistance, besides, flat channel design of honeycomb ceramic filter enable the balance between air flow rate and strength, and to remove the contaminants and cast particulates effectively, which hence improve the casting mechanic capability, surface look and product pass rate greatly.
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.
Application:
*Tower packing-high surface area, uniform distribution fluid, high efficiency of mass transfer
*Catalyst carrier-reduce the oxidation temperature of VOA in purification of industrial exhaus gas
*Thermal regenerative packing-good heat capacity, saving energy 40-70%in RTO system
*Gas combustion distributing plate-distribute uniformly and make the combustion complete, saving energy more than 10%
*Refractory kiln furniture-low bulk density, good thermal efficiency
Standard sizes: 150× 150× 600× 450× 300× 150× 100× 50
Others: 100× 100× 100× 40
Advantages:
*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
