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: 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!
- Q: What are the poor filtration effects of vacuum disc filters?
- With the increase of the material level of the ceramic filter trough, the suction time of the ceramic filter plate in the vacuum zone increases, the thickness of the slurry increases and the productivity increases. But the drying time is relatively short, the water content of the concentrate will be increased. Select the best material level to ensure the production capacity and concentrate moisture requirements.
- Q: Influence factors of ceramic filter
- (1) the particle size and the distribution of the material match the microporous of the ceramic filter plate. Although the ceramic filter plate aperture is bigger, easy to suck the pulp, but easy to cause the ceramic filter board to block up.(2) the ceramic filter plate with the same ceramic filter plate with high pore permeability and high water permeability is selected with high water permeability and good slurry absorption performance. The spindle speed is slow, the formation time of growth in the area of vacuum filter cake, production capacity increased gradually, but because the unit time of grout thickness and spindle speed slow is proportional to, so the ceramic filter capacity in a range of showing the highest.
- Q: What are the causes of the powder moisture in the ceramic filter?
- The main speed of the ceramic filter is too fast.The vacuum of ceramic filter is not enough.The cleaning of ceramic filter has not met the requirement.The ceramic filter plate has a near life and a serious blockage.The selection of ceramic filter plate is different.Too much residual of ceramic scraper after discharge.
- 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: What is the working pressure of the ceramic filter?
- Generally speaking, there are two kinds of working pressure of ceramic filter: vacuum pressure and reverse flushing pressure.
- 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 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: 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: What is the reason that the whole ceramic filter does not attract ore?
- After the joint cleaning, 0~2 hours of suction effect may be good, 2~4 may drop slightly, 4 hours later will become worse and worse, or even suck. This case should first check the backwash water pressure (instantaneous maximum pressure should not be less than 0.08MPa) is to meet the requirements, should also advance down (to ensure normal and ultrasonic cleaning combined with nitric acid dosage sufficient) and prolong the cleaning time.
