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?
- Alumina made from tabular corundum can be used over 1800 degrees!SiC if there is atmosphere, protection will be higher, there is no atmosphere protection, because the existence of oxidation, generally not more than 1600.Corundum, mullite, 1750 degrees small meaning.
- Q: Why should filter core be used in backwash of ceramic filter?
- The filter in the water filter of ceramic filter is used for filtering water.
- Q: Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
- Generally, the vacuum degree of ceramic filter is about -0.08MPa. Sufficient vacuum pressure is only a prerequisite for a good ceramic suction effect. Besides vacuum, the other factors may affect the suction effect:Vacuum display table fault, the difference between the display value and the actual data is great.
- Q: What is the filtration accuracy of 50nm ceramic membrane?
- 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: 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 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: 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.
- Q: What about the leakage of the ceramic filter static and dynamic sealing points?
- 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. Other questions about ceramic filter, welcome to chat with me or look at my head
- Q: How to determine the quality of ceramic fiber filter board simply?
- Ceramic fiber filter board, in fact, ceramic fiber board, also known as aluminum silicate, refractory fiberboard.
