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: Is the filter plate of the ceramic filter afraid of freezing?
- The filter plate of ceramic filter is afraid of frost and should be protected.
- Q: Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
- The spindle speed is too fast.The speed is too high to absorb the filter cake.There are other possible reasons.
- Q: What's the reason for high water content in filtration copper concentrate?
- Vacuum: about -0.08MPaIf the vacuum required to consider other factors; such as the vacuum degree is not up to even only about -0.05MPa, it should be related to pipeline inspection of vacuum system leakage, vacuum pump damage, distribution valve failure, ceramic plate breakage, ceramic plate connecting pipe leakage may cause the vacuum is not up to, to achieve early detection and early treatment.
- 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: Can the plate filter press pass through the filter plate?
- Specific, it is necessary to choose the filter characteristics according to different materials. Plate and frame filter press: plate and frame filter press is an industrial realization of solid, liquid separation, plate and frame filter press is suspension, liquid-solid, liquid two phase, applied to chemical, ceramics, oil
- Q: Common troubles of ceramic filter
- (1) low vacuum, can not meet the production requirements. The main reason is the vacuum pipeline leakage, vacuum pump circulating water is not enough, vacuum pump impeller wear and tear, distribution head wear, ceramic filter plate damage, filtrate tank drainage valve is not closed, pulp trough material level is lower;(2) low or fluctuating backwash water pressure. The main reason is the blockage or leakage of the backwash water pipe system and the distribution of head wear;(3) the liquid level of the filtrate tank is high. The main reason is that the circulating water pump impeller or pump shell wear, pressure is insufficient, so that the drain valve can not open or drain valve itself failure, and filter barrels and circulating water pipe between the leakage;
- Q: The vacuum degree of the ceramic filter is normal and the cake water is large
- There is a difference between the vacuum display and the actual vacuumThe main speed of the ceramic filter is too fastThe water content of the filter cake is gradually increased within 0~8 hours after the equipment has been continuously turned onThe ceramic filter plate does not meet the aperture range and the opening rate is lowThe ceramic filter plate has a near life and serious blockageCeramic filter cleaning standards (acid, ultrasonic, backwash water)The scraper can not be completely discharged, and the surface of the ceramic plate is coated with a thin filter cakeFailure to manufacture equipment or other causes of failure
- Q: What is the reason that ceramic filter does not absorb mineral powder?
- 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: How can I avoid the backwash pressure in the production of ceramic filter?
- The backwashing system of ceramic filter is usually made up of water inlet, water inlet, pressure gauge, water filter and filtered water pressure gauge, and then connected to the inside of ceramic filter. Such as the discovery of ceramic filter recoil pressure became smaller or even no recoil pressure, you can carefully observe the surface of the ceramic filter plate is wet or ceramic filter plate wear without water injection at the discharge point, investigation and the reasons for the following aspects:Is the water inlet pressure or normal?How about the sealing performance of the water filter? Does the filter element need to be replaced?Is the recoil system piping (metal pipe, ceramic filter plate, connecting pipe, etc.) broken, leaking or dripping?Is the distributor valve properly installed and is it worn?Are there any cracks in the ceramic filter plate?Is the pressure gauge broken?The most likely reason is 1, 2, two, the best water should not be too dirty, filter should be replaced regularly. I hope the answer can help you.
- 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.
