Honeycomb Ceramic Filter for Iron Casting:
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. 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
*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.
Honeycomb Ceramic Filter Performance:
*The utilization ratio increasing 5-10%
*Casting tired intensity increases by 15.5%
*Thermal shock, Heat impact resistant: Not break cooling from 1200° C by cold water for 5 times
*Coefficient of thermal expansion: (1000° C) 1.6~5.4*10-6/° C
*Compressive strength in the direction of axis >2~5MPa
*Bulk density: ≥ 0.6~1g/cm3, Water absorption25± 2%
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
