-Improve accepted rate of steel casting

-Reduce foreign matter of steel casting

-Drop twice oxide flaw

-Reduce second-face flaw after machine process



Advantages:

even aperture, high porosity, proper sinter, high strength of anti-flexing and anti-compression, effective filtering.

It is widely applied to the aluminium fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low pressure casting.

Ceramic foam filters are different from aperture specifications from 10 to 45ppi, with different sizes and shapes.

Besides the general specification ,we can offer the product according to the customers requirements.

Q:How to determine the quality of ceramic fiber filter board simply?
Ceramic fiber board quality can be judged from the following aspects:1, appearance. The surface is flat and the cutting surface is well arranged, and vice versa.2 density. Press the hands, and the surface is soft and smooth.3, process. Vacuum suction and continuous production process.4, cross section, slag ball content is low.
Q:Working principle, ultrasonic trouble and troubleshooting of ceramic filter
Ceramic filter is mainly composed of system, roller system, mixing discharge system, vacuum system, liquid discharge system, scraper system, washing system, cleaning system, automatic control system, and these parts body frame.
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:Can the ceramic plate filter the hot air?
The cleaning of the ceramic filter is divided into two parts: reverse flushing (also useful gas) and combined cleaning. The purpose of cleaning is to discharge the particles from the hole to the ceramic filter board. Anti flushing and cleaning water filter after direct visual pressure can, generally between 0.08--0.12MPa, such as less than 0.05MPa, while the poor flushing effect without even washing effect, resulting in blocking accumulation eventually led to the ceramic filter plate hole plugging scrap. Replacing the filter element in time and ensuring the water pressure before filtration can provide stable backwashing water pressure. Combined cleaning by ultrasonic vibration, nitrate dissolution method for maximum remove blockage of backwash rushed out, the general ceramic filter every 8 hours of continuous work should stop cleaning 1 hours, such as the use of the old plate or the suction effect is poor, can strengthen cleaning (such as shorten the cleaning period, prolong the period of cleaning, increase the amount of nitric acid etc.). Other reasons such as 1,2,3 are normal, but can not be discharged from the spindle speed too fast, even the ceramic filter itself manufacturing defects, the user equipment modification and so on, are likely to lead to abnormal operation of equipment. We specialize in ceramic filter boards for many years and welcome exchanges.
Q:The working principle of ceramic filter
Based on the work principle of ceramic filter function of the capillary, by using porous ceramic as filter media, a large number of small capillary action with solid-liquid separation equipment design principle using microporous ceramic disc filter in negative pressure, working conditions, characteristics of the microporous ceramic filter plate with its unique water impermeable, extraction of ceramic filter plate and external vacuum cavity the differential pressure tank suspension material under the action of negative pressure adsorption in the ceramic filter plate, solid material can not through the microporous ceramic filter plate is retained on the surface of the ceramic plate, and the liquid due to the hydrophilic effect of vacuum pressure difference and the ceramic filter plate is passed into the gas-liquid distribution device (vacuum barrel) efflux or recycling so as to achieve the purpose of solid-liquid separation.
Q:Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
Ceramic filter plate.The ceramic filter plate does not match the blockage or selection of new plate porosity is generally around 40%, such as ceramic filter plate has hole blocking, the opening rate will become less, when the suction effect into 30% relatively new plate may be slightly worse, when the ceramic filter plate is used for a long time after the opening rate is 10% or less, then the ceramic filter plate suction effect will become very poor even suction. At this time, even if the vacuum suction is good, also do not suck sizing, you need to replace the new ceramic filter board.
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: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:Performance advantages of ceramic filter
A ceramic filter for fine coal mud recovery, there is a base, the lower part of the frame is provided with a fine slime liquid trough, the fine slime liquid material groove is provided with a liquid level controller, the slime liquid material at both ends of the groove is provided with a negative pressure water tank, the water tank is provided with a negative pressure suction connection assembly fixing the other side is provided with a vacuum pump pipeline, the pipeline is communicated with a vacuum pump and vacuum pump;
Q:Can the plate filter press pass through the filter plate?
Specific, it is necessary to choose the filter characteristics according to different materials. Plate and frame filter press: plate and frame filter press is an industrial realization of solid, liquid separation, plate and frame filter press is suspension, liquid-solid, liquid two phase, applied to chemical, ceramics, oil
