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: Is the filter plate of the ceramic filter afraid of freezing?
- In addition, the temperature is one of the factors affecting the filter suction effect of ceramic filter. The lower the temperature, the worse the suction effect.Therefore, the ceramic filter plate, especially the ceramic filter plate after use, should be protected under low temperature environment.
- Q: What is the filtration accuracy of 50nm ceramic membrane?
- It should be noted that due to wear, plugging and so on, the new and different degrees of ceramic film, the pore size will change. Micron scale ceramic membrane filtration accuracy is very good, nano scale aperture range of such a small ceramic film does not know in what way.
- 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: How much is the accuracy of 50nm ceramic membrane filtration?
- The filtration accuracy is the maximum particle size that the membrane can pass through.
- 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: Does the ceramic factory use hydrochloric acid?
- 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's the acid of the ceramic filter plate?
- General ceramic filter running for eight hours or so, you need to stop for joint cleaning, general cleaning at an hour or so. When washing together, there is acid washing, usually concentrated nitric acid. The purpose is to dissolve the pores in the ceramic filter plate through nitric acid.
- Q: How should the static and dynamic sealing points of the ceramic filter be leaking?
- The filtrate pump works to drain or recycle the water that has been pumped out. 6 、 cleaning system work, cleaning system includes backwashing (water pump pressure or height difference pressure), acid liquid (metering pump, automatic acid injection), ultrasonic (ultrasonic work), etc.. 7 、 control system and other electrical systems. In addition, the filter cake which is absorbed and dried on the ceramic filter plate is unloaded automatically by the scraper and then falls on the belt conveyor, and is conveyed to the concentrate storage yard by a belt conveyor.
- 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?
- The cleaning of the ceramic filter is divided into two parts: reverse flushing (also useful gas) and combined cleaning. The purpose of cleaning is to discharge the particles from the hole to the ceramic filter board. Anti flushing and cleaning water filter after direct visual pressure can, generally between 0.08--0.12MPa, such as less than 0.05MPa, while the poor flushing effect without even washing effect, resulting in blocking accumulation eventually led to the ceramic filter plate hole plugging scrap. Replacing the filter element in time and ensuring the water pressure before filtration can provide stable backwashing water pressure. Combined cleaning by ultrasonic vibration, nitrate dissolution method for maximum remove blockage of backwash rushed out, the general ceramic filter every 8 hours of continuous work should stop cleaning 1 hours, such as the use of the old plate or the suction effect is poor, can strengthen cleaning (such as shorten the cleaning period, prolong the period of cleaning, increase the amount of nitric acid etc.). Other reasons such as 1,2,3 are normal, but can not be discharged from the spindle speed too fast, even the ceramic filter itself manufacturing defects, the user equipment modification and so on, are likely to lead to abnormal operation of equipment.
