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.

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: The ultrasonic wave of ceramic filter is not good. What's going on?
- In ancient China, filtration technology was applied to produce paper made from plant fibers in 200 bc. The paper method was improved in AD 105. He wandered in dense in papermaking during plant fiber pulp fine bamboo. Water curtain gap filtration, a thin layer of wet pulp stay on the bamboo surface, after drying into paper.
- Q: Influence factors of ceramic filter
- On the other hand, as the spindle speed slows down, the thickness of the slurry is thickened, and the moisture of the concentrate is also affected. For viscous material, ceramic filter with ceramic plate to work as filter media, when the cake is formed gradually into the porous filter medium filter cake itself, and the cake is not easy to form a viscous material, forming a dry cake appearance does not slow, the spindle speed is easy to reduce the water content of concentrate. Similarly, the spindle speed is accelerated, the cake formation time in the vacuum zone is shortened, and the slurry thickness is reduced, and the material can be improved for the easy molding material. But the spindle speed is too fast to be cleaned after each cycle of the ceramic plate. As for the viscous material, the cake is difficult to form after the spindle speed increases, and it will affect the capacity. Therefore, the use of ceramic filter should focus on the inherent nature of the concentrate to explore the best spindle speed. Generally, the higher the temperature, the smaller the viscosity of the liquid, the more conducive to improve the filtration rate, reduce the cake or sediment water, while reducing the viscosity of the slurry, can improve the processing capacity.
- Q: What happens when the pressure on the filter plate is uneven during backwashing?
- It should be said that the ceramic filter backwash, usually with a certain pressure of clean water to backwash.
- Q: Why should filter core be used in backwash of ceramic filter?
- Ceramic filter recoil stage is with certain pressure of clean water from the inside out washing ceramic filter plate, the outer aperture ceramic filter plate from inside is gradually reduced, such as flushing water and unclean inside contain impurities that may block ceramic filter board, other structures in the recoil stage of pollution. Such as recoil, water is not clean, you must go through the water filter cartridge to filter again, the choice of filter core, the higher the accuracy of filtration, the more clean water, but the filter is more likely to plug, scrap. Of course, the water is clean and contains little solids. The filter core is not easy to plug and even water filters can be removed.
- Q: The working principle of ceramic filter
- The working principle and mechanism and the shape of ceramic filter disk vacuum filter is similar to that in the pressure under the action of suspension by filtration medium, particles are trapped cake is formed at the surface of the medium, and the liquid through a filter medium outflow, reached the purpose of solid-liquid separation. The difference is that the filter medium of ceramic filter plate with microporous capillary effect, the capillary force in the pores is larger than the vacuum force applied to microporous keep full liquid state, no matter under what circumstances, the ceramic filter plate does not allow air through, because there is no air through solid-liquid separation, low energy consumption, vacuum a high degree of.
- Q: Microporous ceramic filter plate cleaning
- Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.
- Q: How much is the accuracy of 50nm ceramic membrane filtration?
- 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: What's the acid of the ceramic filter plate?
- Ceramic filter automatic control system: control system through the metering pump will be concentrated nitric acid automatic mixing ceramic filter plate into nitrate after proportioning through the pipeline, so that it can be dissolved, dredge the blockage in the most microporous ceramic filter plate. This is the ceramic filter plate pickling, pickling, acid dosage should be sufficient as little pickling effect.
- Q: Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?
- The ceramic filter ceramic plate ceramic microporous pumping vacuum adsorption concentrate filtration water, the adsorption parameters according to the angle of rotation, reverse cleaning process, check whether there are loopholes in the exhaust pipe, check the ceramic plate use cycle is too long.
- 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.
