Ceramic Foam Filters
Zirconia for Steel Foundries
Characteristics
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.
Advantages
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.
Selection
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.
Package
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: 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: 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: Why does not the iron filter of the ceramic filter work?
- You should make it clear that the filter cake has always been dry or suddenly dry, and now how much moisture? Generally, the ceramic filter is used to filter iron powder, and the water content of the filter cake is about 10%.
- Q: The vacuum degree of the ceramic filter is normal and the cake water is large
- The vacuum degree of the ceramic filter is normal at about -0.08MPa. Under normal circumstances, the water content of the filter cake treated with a ceramic filter is about 10%, and the moisture content of the tail filter cake is about 15%. The water content of the filter cake increases with the increase of water content in the ceramic filter. I analyze the reasons from two aspects.
- Q: Ceramic filter capacity.
- You ask too general, to say processing capacity (ie capacity), at least to provide material conditions, such as: material name, concentration, particle size distribution. In addition, the basic conditions of equipment operation should be taken into account.
- 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: What are the reasons for the program alarm of ceramic filter?
- If that is the ceramic filter tank body of the slurry concentration is diluted, has nothing to do with the ceramic filter itself, can think of ways to enter the ceramic filter tank before the slurry concentration increased, thereby improving the dewatering efficiency of ceramic filter.
- Q: How should the static and dynamic sealing points of the ceramic filter be leaking?
- When the ceramic filter works, the operation may be as follows: 1. The feed is injected and the pulp is injected into the tank of the ceramic filter. 2, mixing system, ceramic filter stirring rake back and forth mixing, driven by mixing reducer. 3, spindle rotation, material level reached a certain range, through the spindle speed machine to drive the ceramic filter disk rotation.
- Q: What about the leakage of the ceramic filter static and dynamic sealing points?
- 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?
- Ceramic filter by vacuum suction effect in the ceramic filter plate to cake drying purpose, ceramic filter plate needs cleaning and life, if you discover that the slurry sucking effect is poor or even grout should first consider the three aspects: the two factors of ceramic filtering plate of ceramic filter plate most likely, are fracture and hole plugging: rupture will lead to distortion and poor vacuum cleaning; plugging holes will cause the filter plate suction effect is poor even if grout, ceramic filter plugging hole, can strengthen the appropriate cleaning (such as shortening cleaning cycle, prolong the cleaning time, increase the amount of nitric acid, such as strengthening cleaning etc.) after the effect is still not improved, you should consider the life is approaching should be scrapped and replaced with ceramic filter plate new (replacement plate should not put new or different manufacturers is mounted on the same line, the most OK, complete replacement.).
