Product Description

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.

High performance ceramic filter plate is used as a core component of the ceramic filter, is the company scientific research personnel to fully digest and absorb the international advanced technology and combined with the characteristics of production technology of domestic high-tech ceramics, carefully developed high-tech products.White corundum series are integrated the original production of dry pressing technology, after 1380 degrees high temperature firing, then coated with micron size corundum membrane surface, and firing again. Characteristics as follows:


1: Integrated dry molding technology, without any organic / inorganic paste, the overall strength of a substantial increase in water pressure, air pressure over 0.7MPa.

2: Uniform pore size, clear and transparent filtrate, wide range of application.

3: Unique and reasonable arrangement of inner water channel. No effect of any adhesive gas, water flow, suction and recoil effect better ore.

4: Can use a variety of regeneration methods: high air pressure, high water pressure, high temperature and so on, the regeneration effect is good

*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
