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?
One is leakage, two is no liquid output or output weakness, pressure is too low, cleaning effect is not good, the pressure is too large, will cause damage to the filter plate and reduce the slurry concentration. The recoil pressure is regulated by the pump loop valve and the pressure regulating valve.
Q:What is the working pressure of the ceramic filter?
Vacuum pressure or suction is the vacuum of the equipment, the size of the vacuum directly affects the effect of ceramic filter board suction (yield and water content). The vacuum system of ceramic filter consists of vacuum pumps, tanks, distribution device, ceramic filter plate and a connecting pipe is composed of ceramic filter, the vacuum pump is generally 2BV series water circulation pump, the vacuum pump vacuum limit is -0.097MPa, using a vacuum pump for a long time or vacuum system has poor sealing performance may cause a certain degree of vacuum distortion, so the ceramic filter vacuum is generally difficult to achieve in the -0.097MPa, -0.08 ~ 0.097MPa, which indicates that the vacuum degree is good, such as the vacuum degree is not up to -0.07MPa or less, the vacuum system may be an exception.
Q:Microporous ceramic filter plate cleaning
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. (do not recommend sulphuric acid)
Q:What are the poor filtration effects of vacuum disc filters?
The concentration can change the properties of the suspension, because the viscosity is no longer constant when the concentration of the suspension reaches a certain value, and belongs to the properties of non Newtonian fluid. For the suspension of fine particles, the filter cake resistance of low concentration slurry is higher than that of high concentration slurry, so the filter performance can be improved by increasing concentration. If the concentrate concentration is high and the general treatment capacity is high, the running overflow can be used to increase the concentrate content. The concentrate concentration is too high to influence the agitation, and the high productivity can be achieved by adjusting the overflow position.
Q:What are the causes of the powder moisture in the ceramic filter?
Generally, the ceramic filter is used to filter iron powder, and the water content of the filter cake is about 10%.
Q:The vacuum of ceramic filter is not enough
Maybe the vacuum meter is broken. It doesn't show or show the data is different from the actual data.It could be the source of the vacuum, the vacuum pump failure.Pipeline leakage: vacuum system connecting pipes (metal pipes or rubber pipes) corrosion, aging and water leakage.Distributor head leakage: wear or poor sealing.Leakage of ceramic plate: rupture of ceramic plate.Other reasons.
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:Why should filter core be used in backwash of ceramic filter?
The filter in the water filter of ceramic filter is used for filtering water.
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?
At this time, take the filtrate (this is not the first water slurry) will pollute the ceramic filter pipe, friction ring, filtrate pump, may damage the vacuum system, remaining in the pipeline in the pulp will recoil pressure under the action of pollution caused by the other ceramic plates, ceramic plates blocked him. Once the ceramic plate is broken (depending on the severity), it will make the vacuum distortion, resulting in ceramic filter suction effect worse or even no suction!
