Ceramic Foam Filters

Zirconia for Steel Foundries





Ceramic Foam Filters are designed for the filtration of molten steel, alloy steel, and especially for high quality steel alloys casting temperature up to 1700 °C , which have high porosity (76%-82%), high thremal shock resistance and large specific surface.






Ceramic foam filters help to enhanced quality of castings and reduce cost.


l  Special 3D structure to reduce turbulence of flowing molten metal.

l  Reduce defective rate of castings.

l  Improved mechanical properties of castings.


l  Improved precision of dimensions and shapes of castings.


l  Reduced costs of machining operations.


l  Simplify pouring systems and increase utilization ratio of mold.

Note: Special size and 10-20 pore size (PPI) can be custom made.





1) Pore size is based on casting material and casting weight, regularly 10ppi and 20ppi for steel casting filtration.

2) Filter size is decided by the sculpt, fusion and the characteristic of ceramic foam filter.


The filters are packed in carboard box and pallet protecting them from damage.

Box size: 54x36x28cm.

Pallet size: 1.1x1.1x1.9m.

36 boxes per pallet, 10 pallet per 20’’ container, 20 pallets per 40’’container.

Notice of Application

1. In order to reduce the impact of hot molten metal to filters, pouring bowl shall put down as low as possible from filters.

2. It is recommended to use compressed air to blow dust off from filter before usage.

3. Ceramic foam filters should be stored in dry place to avoid moisture.

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 materials that make up the ceramic mold?
Ceramic membrane, also known as CT film, is one of the solid membrane, the earliest by Japan's large Japanese printing company and Toyo ink company in 1996, the introduction of the market. The ceramic coating is mainly A12O3, Zr02, Ti02 and Si02 of inorganic materials such as porous membrane preparation, the pore size of 250mm. Has good chemical stability, acid resistance, alkali resistance, solvent resistance, high mechanical strength, can reverse flushing: anti microbial ability: high temperature, narrow pore size distribution, higher separation efficiency characteristics, has been widely used in food industry, biological engineering, environmental engineering, chemical industry, petroleum chemical industry, metallurgy industry etc. The market sales, with an annual growth rate of 35% growth. Compared with plastic products of ceramic membrane with similar high cost, but also has many advantages, it is hard to withstand strong, durable, not easy to have chemical resistance village, invasive and high temperature liquid cleaning liquid has a stronger ability to resist, its main drawback is the price expensive. _ complex manufacturing process
Q:Common troubles of ceramic filter
The metering pump is not working properly and backwash water into the bucket of acid. The main reason is that the metering pump is not switched on, the diaphragm is worn out, the frequency is too low, and the check valve of the acid pipe and backwash pipe is worn out.
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?
50nm refers to the nominal pore size, but it does not mean that the holes in the ceramic membrane are 50nm, but the approximate number of holes. The size of the pores may be between 40~60 and 45 to 55nm. Generally introduced, annotated range, you can also own to detect.
Q:The ultrasonic wave of ceramic filter is not good. What's going on?
The earliest filtration was mostly gravity filtration, which was followed by pressure filtration to increase the rate of filtration, followed by vacuum filtration. The drum vacuum filter invented in the early twentieth Century realized the continuous operation of the filter. Since then, various types of continuous filters have appeared. Intermittent operating filters (such as plate and frame press filters) are developed for automatic operation, and the filtration area is becoming larger and larger. In order to obtain the filter residue with low moisture content, the mechanical press filter has been developed.
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:Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
The filtrate is not discharged smoothly.The filtrate can not be discharged in a timely and smooth manner, the new filtrate can not be sucked out, and the filtrate can not be continuously sucked out, so that the filter cake can not be adsorbed on the ceramic plate.
Q:What is the backwashing pressure of the ceramic filter?
It should be said that the ceramic filter backwash, usually with a certain pressure of clean water to backwash.
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!
