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:What is the reason that ceramic filter does not absorb mineral powder?
There may be a failure of the filtrate pump, the diaphragm of the pump is damaged, and the mechanical seal of the pump is invalid
Q:Principle of chemical engineering drum vacuum filter, the faster the speed, the less the amount of filtrate obtained per turn, the more the amount of filtrate obtained per unit time?
In unit time, the more turns of the drum, the greater the centrifugal force, the greater the rate of filtration in unit time, that is to say, the amount of filtrate in unit time is moreRotating drum vacuum filter, the greater the speed, the greater the filtration rate, but the shorter the time each turn, the amount of each filtrate will be reduced
Q:What are the causes of the powder moisture in the ceramic filter?
The main speed of the ceramic filter is too fast.The vacuum of ceramic filter is not enough.The cleaning of ceramic filter has not met the requirement.The ceramic filter plate has a near life and a serious blockage.The selection of ceramic filter plate is different.Too much residual of ceramic scraper after discharge.
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 can I avoid the backwash pressure in the production of ceramic filter?
The backwashing system of ceramic filter is usually made up of water inlet, water inlet, pressure gauge, water filter and filtered water pressure gauge, and then connected to the inside of ceramic filter. Such as the discovery of ceramic filter recoil pressure became smaller or even no recoil pressure, you can carefully observe the surface of the ceramic filter plate is wet or ceramic filter plate wear without water injection at the discharge point, investigation and the reasons for the following aspects:Is the water inlet pressure or normal?How about the sealing performance of the water filter? Does the filter element need to be replaced?Is the recoil system piping (metal pipe, ceramic filter plate, connecting pipe, etc.) broken, leaking or dripping?Is the distributor valve properly installed and is it worn?Are there any cracks in the ceramic filter plate?Is the pressure gauge broken?The most likely reason is 1, 2, two, the best water should not be too dirty, filter should be replaced regularly. I hope the answer can help you.
Q:The efficiency of ceramic filter is low. What's wrong with it?
Ceramic filter is a new and efficient dehydration equipment. If users find the ceramic filter board surface suction effect is poor, or even do not suck slurry, we should promptly investigate the causes, so as not to affect production efficiency.
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: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.
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: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
