Silicon Carbide Ceramic Foam Filter
Silicon Carbide Ceramic Foam filter is justdeveloped as a new type molten metal filter to decrease casting flaw in recentyears. With its characteristics of light-weight, high mechanical strength,large specific surface areas, high porosity, excellent thermal shockresistance, erode resistance, high-performance, silicon carbide ceramic foam filter is designedfor filtering impurities from molten Iron & Alloy, nodular cast ironcastings, grey iron castings and malleable castings, etc.
CNBM silicon carbide ceramic foamfilter ischaracterized by high porosity and mechanochemical stability and excellentresistance to thermal shock and corrosion from moltenmetal. It can effectively remove inclusions, reducetrapped gas and provide laminar flow when iron molten metal filtrated, ceramicfoam filter is machined to tight dimensional tolerance during production,this combination of physical properties and precise tolerance make them firstchoice for iron molten metal filtration.

- 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:What are the causes of the powder moisture in the ceramic filter?
- The ore condition has changed, such as high concentration of material, fine grain size and increase of mud content.
- Q:How can I avoid the backwash pressure in the production of ceramic filter?
- Recoil of the ceramic filter is on the clean water under certain pressure, from the inside out flushing blockage blockage in the ceramic filter plate on the internal pore water pressure, the recoil is generally less than 0.12MPa, the pressure is too small or no recoil recoil effect is not good.
- Q:What's the reason for high water content in filtration copper concentrate?
- Ceramic filter plate1) the service life of the ceramic filter plate has arrived.2), ceramic filter plate uneven in quality on the market, the production capacity of some ceramic products difference (table mask size is too large or pore size uniformity is poor as a result of suction effect is poor, short life), but the price is low, but some users in order to reduce the operation cost of ceramic machine, tend to choose low price the ceramic plate, sometimes a ceramic machine ceramic filter plate with several may be different, so do not get the expected effect in normal use.In addition, the concentrator slurry, especially metal slurry, is very powerful on the wear of ceramic filter plate, the mechanical strength and wear resistance of ceramic filter plate requirements (corundum has high mechanical strength, good abrasion resistance, especially suitable for metal slurry dehydration).When selecting ceramic filter boards, these two points should be taken as a reference.
- 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: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:How many degrees does the ceramic filter melt?
- Spinel is basically over 1600-1700. It's not too acid proof.There are other materials such as silicon nitride. Ceramics can be more than 1300 degrees in temperature. So the material you are using now is unlikely to melt and melt, and you can change it into one of the top materials. Baidu, this stuff is all over the street.
- 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:Ceramic filter suddenly do not smoke, a little later on their own good, what reason?
- The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.
- 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.
