High Alumina Ceramic Foam Filter for Foundry Industry

high silica mesh casting filter can effectively remove slag,refractory particles and non-metallic inclusions from molten metals.It is developed as a low cost but with rather filtration efficiency alternative to ceramic filters.
Made from specially treated silica yarns,silica mesh filters are capable of withstanding pouring temperatures up to 1620 Degree C.
Silica mesh filters are ideal for in-mold filtration of gray, malleable,white,compacted graphite and ductile cast irons, as well as non-ferrous aluminum and copper-based metal alloys and many types of small scale steel casting filtration.

ADVANTAGES:

• Low cost and easy to use

• Improves fluidity and metal distribution

• Removes micron sized inclusions and impurities

• Can be used with existing pattern equipment

• Eliminates inclusions created by ceramic chips

APPLICATIONS:

• Cut pieces for in mold filtration like sand casting,gravity casting,etc.

• Cut pieces for riser sleeves,bottom or across ports in walls

• Cut pieces to provide a weakened plane for riser knock-off

• Cup shapes for investment casting

FILTERING TIPS:

• Copper alloys&leaded bronze:1.5x1.5mm mesh

• Gray Iron:1.5x1.5mm mesh

• Ductile Iron:2.0x2.0mm &2.5x2.5mm mesh

• Small scale steel:1.5x1.5mm mesh

*Cut pieces can be rectangular or round,size from 20mm to 900mm.

*Preformed cup filter OD can be 100/110/115/120mm or as per request.

Q:What filter material are placed in the aquarium filter?: Submerged in water. Submersible pumps and filter cotton (often replaced by sponge) installed in one, and some brands will also be installed heaters, which become multi-purpose fish farming equipment. When working, the water is absorbed into the filter in many directions, and the filtered water is returned to the water tank by other means. This filter because of its low price and popular beginners of all ages, but the effects from the use of view, only suitable for small fish density, on the flow and filtration requirements are not high, a small aquarium, "fish" will be built in filter (especially the heating function of the filter for seedling and foster) water tank. The effect is very good. The biggest disadvantage of this device is that when it stops working, a lot of dirt stuck to the filter runs back into the water.

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:Ceramic filter fineness thin mud suction is not what to do more: Users such as pulp size is too small, too much mud, after analysis, the following methods of testing, the results have improved, it may wish to try the following methods, perhaps of help:The vacuum degree is about -0.08MPa.Adjust spindle speed and increase drying time.Ceramic filter plate with suitable pore size range.Ceramic filter plate brand on the market range, its quality is good or bad, the feed condition itself is not an ideal situation, such as ceramic filter plate with the aperture to the mine conditions do not match, it will exacerbate the effects of poor, life is short.It can shorten the combined cleaning cycle, strengthen the cleaning effect and prolong the cleaning time.

Q:What are the functions of honeycomb ceramic filters?: At present, it is widely used in metallurgy, foundry industry, metal melt filtration, using mullite (cordierite) ceramic materials

Q:Can the plate filter press pass through the filter plate?: There are many types of pumps to be used, such as screw pumps, slag pumps, rotary pumps, piston pumps, and diaphragm pumps.

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:The ceramic filter suddenly did not smoke, and later he was all right. What's the 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 is poor, I hope to help you:

Q:Why does not the iron filter of the ceramic filter work?: You should make it clear that the filter cake has always been dry or suddenly dry, and now how much moisture? Generally, the ceramic filter is used to filter iron powder, and the water content of the filter cake is about 10%.

Q:How should the static and dynamic sealing points of the ceramic filter be leaking?: When the main shaft is rotated, the filter cake is adsorbed on the surface of the ceramic filter plate and dehydrated by the vacuum generated by the vacuum pump.

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.
