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: 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: Is the filter plate of the ceramic filter afraid of freezing?
- The ceramic filter plate by table and the distribution of a large number of porous capillary ceramic filter, when working in the water slurry channel is used so the microporous ceramic filter plate internal residual has a lot of water, such as low temperature, the inside of the frozen water volume will swell, causing damage to the ceramic the inside of the microporous filter plate structure.
- Q: What are the poor filtration effects of vacuum disc filters?
- With the increase of the material level of the ceramic filter trough, the suction time of the ceramic filter plate in the vacuum zone increases, the thickness of the slurry increases and the productivity increases. But the drying time is relatively short, the water content of the concentrate will be increased. Select the best material level to ensure the production capacity and concentrate moisture requirements.
- 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?
- The filter in the water filter of ceramic filter is used for filtering water.
- 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: What is the filtration accuracy of 50nm ceramic membrane?
- 50nm refers to the nominal pore size, but it does not mean that the holes in the ceramic membrane are 50nm, but the approximate number of holes. The size of the pores may be between 40~60 and 45 to 55nm. Generally introduced, annotated range, you can also own to detect.
- Q: The efficiency of ceramic filter is low. What's wrong with it?
- 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 these three aspects:Ceramic filter plateTwo factors of ceramic filter plate most likely, respectively is the rupture and plugging holes: the 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 cleaning (such as shorten the cleaning cycle, prolong the cleaning time, increase the amount of nitrate), such as strengthening the cleaning effect is still not improved, it should consider the life 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, best can complete change).Vacuum system failureThe vacuum degree of ceramic filter is usually about -0.085MPa. If the abnormal vacuum is found, the normal vacuum suction can not be provided, and the suction effect will be poor, or even the pulp will not be sucked.If the vacuum is abnormal, should adhere to the vacuum pump, vacuum connection pipe is whether the fault Water Leakage leakage, distribution valve friction sealing, ceramic filter plate is connected with the rubber tube is aging or exfoliation, ceramic filter plate rupture.
- Q: Does the ceramic factory use hydrochloric acid?
- In order to avoid the possibility of plugging, ceramic filter plates with suitable aperture range of different manufacturers can be selected.
- Q: What is the backwashing pressure of the ceramic filter?
- The working process of ceramic filter is: suction - drying - unloading - backwash - suction - drying - unloading - backwash...... In circulation, suction, the drying process is to make the slurry liquid by vacuum suction and capillary effect (usually water) through the filter media from the left, the filter cake on the filter medium (the two processes like syringe pumping), and then through the scraper discharge, after unloading, ceramic filter machine is complete a cycle in the absorption slurry, drying process, some fine particles may enter the filter medium or stacked on the surface (a lot of pipeline internal filtration medium ceramic filter plate), these small particles blockage will make the filter medium permeability and filtering effect of the loss from the poor, in order to reduce the possibility of blockage ceramic filter, will enter the backwash (this process is like a water jet injector). Ceramic filter backwash is through the pressure of water, these small particles plug discharge ceramic filter board.
