Product Description:

Silicon Carbide Ceramic Foam Filter for iron castings


Products confirm with China National Standard GB/T 25139-2010.

Application:For the filtration of molten Iron,copper ,aluminum and alloy.


Silicon carbide ceramic foam filters are mainly designed to improve the quality of iron castings. The filter can effectively remove non-metallic inclusions including slag and dross from the molten metal stream.Additionally, they aid in reducing turbulence in the gating system.
SIC ceramic foam filter's outstanding thermal shock resistance and high strength properties were developed for superior performance in extreme iron or aluminum and copper based alloy foundry applications.

Product Features:

-Precise sizes control during filter media sponge cutting to final sinter.
-High strength with enough slurry and free from loose debris,no break and no filter slag
-Branded main raw material to ensure stable quality
-Good porosity and free from block during pouring molten metal
-Mature sintering technology to ensure high refractory and good thermal shock resistance.

Q:How should the static and dynamic sealing points of the ceramic filter be leaking?
When the main shaft is rotated, the filter cake is adsorbed on the surface of the ceramic filter plate and dehydrated by the vacuum generated by the vacuum pump.
Q:Can the ceramic plate filter the hot air?
The vacuum degree of the ceramic filter in the vacuum system is about -0.085MPa. If the abnormal vacuum is found, the normal vacuum suction will not be available, and the suction effect will be poor, even without suction. If the vacuum is abnormal, should adhere to the vacuum pump, vacuum connection pipe is whether the fault Water Leakage leakage, distribution valve friction sealing, ceramic filter plate is connected with the rubber tube is aging or exfoliation, ceramic filter plate rupture.
Q:The working principle of ceramic filter
The working principle and mechanism and the shape of ceramic filter disk vacuum filter is similar to that in the pressure under the action of suspension by filtration medium, particles are trapped cake is formed at the surface of the medium, and the liquid through a filter medium outflow, reached the purpose of solid-liquid separation. The difference is that the filter medium of ceramic filter plate with microporous capillary effect, the capillary force in the pores is larger than the vacuum force applied to microporous keep full liquid state, no matter under what circumstances, the ceramic filter plate does not allow air through, because there is no air through solid-liquid separation, low energy consumption, vacuum a high degree of.
Q:Microporous ceramic filter plate cleaning
Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.
Q:Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems
Equipment comes with cleaning:Ceramic filter comes with a combined cleaning system, usually to ensure the normal backwash water pressure, combined cleaning (nitric acid + ultrasonic + backwash) time is sufficient, sufficient amount of nitric acid.
Q:How much is the accuracy of 50nm ceramic membrane filtration?
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:How can I avoid the backwash pressure in the production of ceramic filter?
Recoil of the ceramic filter is on the clean water under certain pressure, from the inside out flushing blockage blockage in the ceramic filter plate on the internal pore water pressure, the recoil is generally less than 0.12MPa, the pressure is too small or no recoil recoil effect is not good.
Q:Ceramic filter suddenly do not smoke, a little later on their own good, what reason?
How old the general ceramic filter suction main reason mud cake thickness is not much of a ceramic filter plate is different, because the ceramic filter backwash water, vacuum suction and nitrate are through the distribution valve, are often the same boat". See your description, you do not know the 5 line is about "5 disc or sideways 5 rows of ceramic plates, that is completely not suction or suction effect
Q:What is the filtration accuracy of 50nm ceramic membrane?
The filtration accuracy is the maximum particle size that the membrane can pass through.
Q:The ceramic filter plate is broken. What will happen to the vacuum pump?
If it is found that the ceramic plate is broken, it should stop in time to replace the broken ceramic plate. Ceramic filter is produced by vacuum suction vacuum pump to the pulp in the water through the ceramic plate away, the surface aperture ceramic plate for several microns, so it can intercept the cake on the ceramic plate on the surface, if the ceramic plate is broken, a hole is a few millimeters, when the vacuum suction pump when they go together along with the pulp pump.
