1.Production of ceramic foam filter

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, 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.

2. Functions of ceramic foam filter

1). Thermal and chemical stability in high temperature,avoiding the chemical reaction with the filtered molten metal;

2). High porosity and good mechanical strength in high temperature due to its pure ceramic composite;

3). Low head loss,easy operation,energy-saving;

4). Making metal liquid flowing at stable speed and avoiding the sputtering and backset,thus increasing the surface quality of the cast part,preventing the pore disfigurement and finally lower down the unqualified rate;

5). Various sizes,shapes,apertures are available for kinds of foundry technique.

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 suddenly did not smoke, and later he was all right. What's the 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: How many degrees does the ceramic filter melt?: You should say clearly what ceramic you useHowever, as a melting furnace or filter medium, alumina products are the most versatile, but also silicon carbide, corundum, mullite, spinel and so on. They use very high temperatures.

Q: What are the causes of the powder moisture in the ceramic filter?: The main speed of the ceramic filter is too fast.The vacuum of ceramic filter is not enough.The cleaning of ceramic filter has not met the requirement.The ceramic filter plate has a near life and a serious blockage.The selection of ceramic filter plate is different.Too much residual of ceramic scraper after discharge.

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 is the working pressure of the ceramic filter?: Generally speaking, there are two kinds of working pressure of ceramic filter: vacuum pressure and reverse flushing pressure.

Q: Microporous ceramic filter plate cleaning: For the use of a long time, the method 1, the effect is still no significant improvement, that is how to plug the ceramic filter plate regeneration? The ceramic filter plate with uneven or non sucking slurry can be removed, and oxalic acid or other acid liquid with certain concentration and certain temperature can be taken together to dredge the microporous of the ceramic filter plate. (do not recommend sulphuric acid)

Q: What is the reason that ceramic filter does not absorb mineral powder?: One is leakage, two is no liquid output or output weakness, pressure is too low, cleaning effect is not good, the pressure is too large, will cause damage to the filter plate and reduce the slurry concentration. The recoil pressure is regulated by the pump loop valve and the pressure regulating valve.

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.
