Product Description:

 Ceramic Foam Filter has the advantages of high porosity, good thermal shock resistance,high mechanical strength, large specific surface and stable chemical property. In addition, with the excellent function of filtering, residuum collection and absorption, it can remove the impurities of 1-10μm efficiently. The outstanding three dimensional structure can reduce the turbulence and extrude the air in mould filling, provide consistent and rapid metal flow, improve the casting quality prominently.Ceramic Foam Filter can also be applied in gas treatment at high temperature, carrier of catalyzer, solid thermal exchange and special filling for chemical industry.
With more than ten years of research and development, enriches its product scope with different series of foam filters such as Alumina, Silicon Carbide and Zirconia.
Alumina foam filter (JG-1): For molten metal filtering under the temperature of 1200
;
Silicon Carbide foam filter (JG-201, JG-202): For molten metal filtering under the temperature of 1550

Zirconia foam filter (JG-3): For molten metal filtering under temperature of 1700.

APPLICATION OF  CERAMIC FOAM FILTER
Selection of 
 ceramic foam filter
1) Selection of pore size is based on the weight and material of casting, regularly 10ppi for Stainless Steel; 10ppi for Ductile Iron; 20ppi for Grey Iron; 15ppi, 20ppi and 30ppi for non-ferrous alloy castings:
2) Foam filter size is decided by the sculpt, fusion and the characteristic of the ceramic foam filters.
3)'Ceramic foam filters should be fixed in the runner and ensure its uniform pressure.
4) Strictly control the pouring pressure and reduce the impact of hot molten metal.
5) Ceramic foam filters under ultra-high temperature are prohibited.
6) Strictly avoid using the ceramic foam filters to control the flow speed of molten metals

Attentions for store and application
Ceramic foam filters should be stored in dry environment to avoid moisture. Ceramic foam filters are fragile materials, rough handling in transportation is prohibited.  It is recommended to blow the scum with compressed air before using

The advantage of application ofceramic foam filter
1) Reduce the defective rate and improve the casting yield.
2) Reduce the machining allowances and improve machinability of casting.
3) Improve the mechanical property of casting
4) Simplify pouring systems and improve the utilization ratio of mould


TYPICAL INSTALLATION OF CERAMIC FOAM FILTERS

Based on the characteristic of casting and the filters' working condition, ceramic foam filters can be fixed in different parts of the pouring system

1、Installation in the pouring cup: Commonly for precision casting and the casting of iron model covers the granulated substance
2、Horizontal installation in vertical runner: For small part with few pouring molten iron, especially for casting system with a vertical runner located at mould center and multiple branches of horizontal runner
3、Horizontally installation in horizontal runner: It makes molten metal casting stable, avoiding directly impacting the filter. This will increase slag blocking ability and make installation convenient.
4、Vertically installation in horizontal runner: To increase molten metal flow speed and enhance the filling capacity. Since molten metal directly impacts the fillers, the impact resistance of filters should be considered

Q:Can the ceramic plate filter the hot air?
Ceramic filter by vacuum suction effect in the ceramic filter plate to cake drying purpose, ceramic filter plate needs cleaning and life, if you discover that the slurry sucking effect is poor or even grout should first consider the three aspects: the two factors of ceramic filtering plate of ceramic filter plate most likely, are fracture and hole plugging: rupture will lead to distortion and poor vacuum cleaning; plugging holes will cause the filter plate suction effect is poor even if grout, ceramic filter plugging hole, can strengthen the appropriate cleaning (such as shortening cleaning cycle, prolong the cleaning time, increase the amount of nitric acid, such as strengthening cleaning etc.) after the effect is still not improved, you should consider the life is approaching should be scrapped and replaced with ceramic filter plate new (replacement plate should not put new or different manufacturers is mounted on the same line, the most OK, complete replacement.).
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: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:What is the reason that the ceramic filter does not absorb mineral powder?
There may be a fault filtrate pump, diaphragm pump damage, pump mechanical seal failure, a leak, two is no output or output to the liquid, the pressure is too low, the cleaning effect is not good, the pressure is too large, will cause damage and reduce the concentration of slurry filter plate.
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: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:How many degrees does the ceramic filter melt?
Alumina made from tabular corundum can be used over 1800 degrees!SiC if there is atmosphere, protection will be higher, there is no atmosphere protection, because the existence of oxidation, generally not more than 1600.Corundum, mullite, 1750 degrees small meaning.
Q:The ultrasonic wave of ceramic filter is not good. What's going on?
In ancient China, filtration technology was applied to produce paper made from plant fibers in 200 bc. The paper method was improved in AD 105. He wandered in dense in papermaking during plant fiber pulp fine bamboo. Water curtain gap filtration, a thin layer of wet pulp stay on the bamboo surface, after drying into paper.
Q:Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
Generally, the vacuum degree of ceramic filter is about -0.08MPa. Sufficient vacuum pressure is only a prerequisite for a good ceramic suction effect. Besides vacuum, the other factors may affect the suction effect:Vacuum display table fault, the difference between the display value and the actual data is great.
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:
