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:Influence factors of ceramic filter
(1) the particle size and the distribution of the material match the microporous of the ceramic filter plate. Although the ceramic filter plate aperture is bigger, easy to suck the pulp, but easy to cause the ceramic filter board to block up.(2) the ceramic filter plate with the same ceramic filter plate with high pore permeability and high water permeability is selected with high water permeability and good slurry absorption performance. The spindle speed is slow, the formation time of growth in the area of vacuum filter cake, production capacity increased gradually, but because the unit time of grout thickness and spindle speed slow is proportional to, so the ceramic filter capacity in a range of showing the highest.
Q:Can the plate filter press pass through the filter plate?
There are many types of pumps to be used, such as screw pumps, slag pumps, rotary pumps, piston pumps, and diaphragm pumps.
Q:Microporous ceramic filter plate cleaning
In order to avoid the possibility of plugging, ceramic filter plates with suitable aperture range of different manufacturers can be selected.
Q:Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems
Oxalic acid immersion:For the use of a long time, the method 1, the effect is still no significant improvement, that is how to plug the ceramic filter plate regeneration? The ceramic filter plate with uneven or non sucking slurry can be removed, and oxalic acid or other acid liquid with certain concentration and certain temperature can be taken together to dredge the microporous of the ceramic filter plate.
Q:What is the reason that the ceramic filter does not absorb mineral powder?
The recoil pressure is regulated by the pump loop valve and the pressure regulating valve. In order to avoid frequent fluctuations in pressure and pressure within a short period of time, a buffer cylinder with a stabilizing effect is provided in the backwash pipe.
Q:Performance advantages of ceramic filter
A ceramic filter for fine coal mud recovery, there is a base, the lower part of the frame is provided with a fine slime liquid trough, the fine slime liquid material groove is provided with a liquid level controller, the slime liquid material at both ends of the groove is provided with a negative pressure water tank, the water tank is provided with a negative pressure suction connection assembly fixing the other side is provided with a vacuum pump pipeline, the pipeline is communicated with a vacuum pump and vacuum pump;
Q:How many degrees does the ceramic filter melt?
You should say clearly what ceramic you useHowever, as a melting furnace or filter medium, alumina products are the most versatile, but also silicon carbide, corundum, mullite, spinel and so on. They use very high temperatures.
Q:The vacuum degree of the ceramic filter is normal and the cake water is large
There is a difference between the vacuum display and the actual vacuumThe main speed of the ceramic filter is too fastThe water content of the filter cake is gradually increased within 0~8 hours after the equipment has been continuously turned onThe ceramic filter plate does not meet the aperture range and the opening rate is lowThe ceramic filter plate has a near life and serious blockageCeramic filter cleaning standards (acid, ultrasonic, backwash water)The scraper can not be completely discharged, and the surface of the ceramic plate is coated with a thin filter cakeFailure to manufacture equipment or other causes of failure
Q:The ceramic filter suddenly did not smoke, and later he was all right. What's the reason?
Ceramic filter is mainly ceramic filter plate and vacuum system, ceramic filter plate is mainly product size of ceramic plate is a new, different manufacturers of different sizes; the vacuum system can be gradually investigation vacuum components and pipelines.The ore concentration, fineness and the concentration distribution in the slurry tank are different.A ceramic filter is composed of a plurality of system, more prone to such an unknown problem, fortunately: good!
