Ceramic Foam Filter
1. Introduction:

Foam Ceramic are mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses . With their excellent thermal shock resistance and corrosion resistance from molten aluminum, they can effectively eliminate inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

SIC Ceramic Foam filters are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance,SIC Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.

Ceramic Foam Filter For Foundry

Q: The ultrasonic wave of ceramic filter is not good. What's going on?: The earliest filtration was mostly gravity filtration, which was followed by pressure filtration to increase the rate of filtration, followed by vacuum filtration. The drum vacuum filter invented in the early twentieth Century realized the continuous operation of the filter. Since then, various types of continuous filters have appeared. Intermittent operating filters (such as plate and frame press filters) are developed for automatic operation, and the filtration area is becoming larger and larger. In order to obtain the filter residue with low moisture content, the mechanical press filter has been developed.

Q: What filter material are placed in the aquarium filter?: Generally let off the filter cotton and ceramic rings, there are biochemical balls, coral bone, stone, activated carbon and so onConditional: filter cotton, ceramic ring, biochemical ball, coral bone, stone, activated carbon

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: 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: What's the reason for high water content in filtration copper concentrate?: Can the cleaning of ceramic plate meet the requirement?Such as cleaning of ceramic plate is not up to the requirements, plugging holes will increase the risk of ceramic plate, ceramic plate plug serious suction effect will become worse (filter cake moisture content increased, cake thickness reduction), cleaning of ceramic plate refers to washing and cleaning.Backwash to ensure that the water filter filter water pressure in the 0.1MPa or so, at least not less than 0.07MPa or less, it is necessary to consider before the filter water pressure is low or water filter element needs to be replaced.Joint cleaning to ensure that the ultrasonic can be no trouble, every time cleaning the amount of nitric acid up to standard. If the filtration effect is not ideal, the cleaning cycle can be washed from 45--60 every 8 hours, changed to 6--7 hours and cleaned for more than 1 hours.

Q: What are the materials that make up the ceramic mold?: At present, the commercialized porous ceramic membranes are mainly composed of 3 types: flat plate, tubular and multi channel. Flat film is mainly used for small-scale industrial production and laboratory research. The tubular membrane is combined with rice to form a heat exchanger similar to a column tube heat exchanger, which can increase the loading capacity of the membrane, but is gradually withdrawn from industrial application due to its strength problem. The size of the applied ceramic membrane usually adopts a multi channel configuration, that is, a plurality of channels are distributed on a circular cross-section, and the number of general channels is 7, 19 and 37. The main business of the inorganic ceramic membrane preparation technology: using solid particle sintering preparation carrier and microfiltration membrane by sol-gel method in the preparation of ultrafiltration membrane: glass membrane by phase separation method: using special technology (such as chemical vapor deposition, electroless plating, etc.) the preparation of microporous membrane or dense membrane. Its basic theory involves colloid and surface chemistry, material chemistry, solid state ion science, material processing and so on.

Q: Common troubles of ceramic filter: The metering pump is not working properly and backwash water into the bucket of acid. The main reason is that the metering pump is not switched on, the diaphragm is worn out, the frequency is too low, and the check valve of the acid pipe and backwash pipe is worn out.

Q: Excuse me, what's the reason that all ceramic filters do not attract ore?: Whether the ore conditions are changed, such as pulp type, mud content, fineness, concentration, etc..

Q: Ceramic filter suddenly do not smoke, a little later on their own good, what reason?: How old the general ceramic filter suction main reason mud cake thickness is not much of a ceramic filter plate is different, because the ceramic filter backwash water, vacuum suction and nitrate are through the distribution valve, are often the same boat". See your description, you do not know the 5 line is about "5 disc or sideways 5 rows of ceramic plates, that is completely not suction or suction effect
