Product Description:

APPLICATION:For the filtration of molten aluminum and non ferrous alloy.

Alumina Ceramic Foam Filters mainly for filtration of aluminum and alloys in foundries and cast houses .With the excellent
resistance to attack and corrosion from molten aluminum, the filter can effectively remove inclusions, reduce trapped gas
and provide laminar flow and then the filtered metal is significantly cleaner.Cleaner metal results in higher-quality castings,
less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

-Reduce scrap related to inclusions.
-Reduce costs related to inclusion defects.
-Increase productivity with higher extrusion or rolling speeds.
-Increase casting flexibility with easy alloy changes.
-No holding metal.

FEATURES:
*Superior dimensional tolerances
*Stable chemical composition
*Highest filtration efficiency
*Excellent strength
*Resistant to corrosion attack by molten aluminum and alloys
*Beveled edges and compressible gasket

Q:What is the filtration accuracy of 50nm ceramic membrane?
It should be noted that due to wear, plugging and so on, the new and different degrees of ceramic film, the pore size will change. Micron scale ceramic membrane filtration accuracy is very good, nano scale aperture range of such a small ceramic film does not know in what way.
Q:Ceramic filter suddenly do not smoke, a little later on their own good, what reason?
The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.
Q:What are the causes of the powder moisture in the ceramic filter?
The ore condition has changed, such as high concentration of material, fine grain size and increase of mud content.
Q:Ceramic filter capacity.
60 square meters of ceramic filter power 35kW or so, a high degree of automation, each class can complete the operation.
Q:Excuse me, what's the reason that all ceramic filters do not attract ore?
Vacuum system failure, no vacuum or vacuum can not meet the requirements. Should check the vacuum pump and vacuum piping, distribution head, ceramic plate, such as failure or leakage.
Q:The ultrasonic wave of ceramic filter is not good. What's going on?
In ancient China, filtration technology was applied to produce paper made from plant fibers in 200 bc. The paper method was improved in AD 105. He wandered in dense in papermaking during plant fiber pulp fine bamboo. Water curtain gap filtration, a thin layer of wet pulp stay on the bamboo surface, after drying into paper.
Q:What is the backwashing pressure of the ceramic filter?
Ceramic filter is a kind of solid-liquid separation, dehydration drying equipment, such as dehydration pulp, mortar. The backwash of ceramic filter is to flush the filter medium (ceramic filter plate) with clean water with a certain pressure.
Q:The vacuum degree of the ceramic filter is normal and the cake water is large
The concentration, particle size and mud content of the raw materials are not suitable for or due to changes, which are no longer suitable for dehydration using ceramic filters
Q:What is the reason that the whole ceramic filter does not attract ore?
Vacuum system failure, no vacuum or vacuum can not meet the requirements. Should check the vacuum pump and vacuum piping, distribution head, ceramic plate, such as failure or leakage.Whether the ore conditions are changed, such as pulp type, mud content, fineness, concentration, etc..
Q:Can the ceramic plate filter the hot air?
The cleaning of the ceramic filter is divided into two parts: reverse flushing (also useful gas) and combined cleaning. The purpose of cleaning is to discharge the particles from the hole to the ceramic filter board. Anti flushing and cleaning water filter after direct visual pressure can, generally between 0.08--0.12MPa, such as less than 0.05MPa, while the poor flushing effect without even washing effect, resulting in blocking accumulation eventually led to the ceramic filter plate hole plugging scrap. Replacing the filter element in time and ensuring the water pressure before filtration can provide stable backwashing water pressure. Combined cleaning by ultrasonic vibration, nitrate dissolution method for maximum remove blockage of backwash rushed out, the general ceramic filter every 8 hours of continuous work should stop cleaning 1 hours, such as the use of the old plate or the suction effect is poor, can strengthen cleaning (such as shorten the cleaning period, prolong the period of cleaning, increase the amount of nitric acid etc.). Other reasons such as 1,2,3 are normal, but can not be discharged from the spindle speed too fast, even the ceramic filter itself manufacturing defects, the user equipment modification and so on, are likely to lead to abnormal operation of equipment. We specialize in ceramic filter boards for many years and welcome exchanges.
