Silicon Carbide Ceramic Foam Filter

China Silicon Carbide Ceramic Foam Filter Factory In Store

Silicon Carbide foam ceramic filter is known for its excellent strength and resistance to high temperature impact and chemical corrosion, and can withstand high temperatures up to about 1500°C. Suitable for casting all copper alloys and cast iron, can effectively improve the quality of cast iron and reduce the scrap rate. Whether it is gray iron, ductile iron or other complex large precision hardware parts, silicon carbide foam ceramic filters can play an excellent filtering effect.

Silicon carbide foam ceramic filters are mainly used in auto parts, diesel engine parts, compressors, wind power castings, high-end machine tool castings, etc., which greatly improves the quality and competitiveness of Chinese castings, while increasing profits. Foundry enterprise.

Can be customized according to customer needs.

The silicon carbide foam ceramic filter has the function of adsorption, filter cake, rectification and mechanical screening, which can efficiently filter out the magazine in the metal liquid and reduce the casting scrap rate.

The use of silicon carbide increases the graphite nucleation capacity, reduces the white mouth tendency, and improves the tensile strength of the casting.

The use of silicon carbide foam ceramic filters does not cause elemental pollution of liquid metal, and plays a certain role in ensuring a reasonable proportion of liquid metal.

The overall use principle of the silicon carbide foam ceramic filter: the silicon carbide foam ceramic filter is placed in the position of the pouring system: the lower end of the straight runner, the cross runner, the inner runner, the pouring cup.

1. The closer the placement position is to the casting cavity, the better to reduce the probability of secondary oxidation;

2. The design of the pouring system is simple, without considering other slag retaining measures, which can improve the utilization rate of sand mold and process yield;

3. The working area of the filter should be 4 to 6 times the choke section of the pouring system to ensure that the pouring speed is not affected;

4. According to the type of casting alloy and pouring temperature, the corresponding filter should not be used over temperature;

5. Select the right aperture to really play a filtering effect;

6. Filter can not be used to control the pouring speed.

Select the porosity of the filter according to the type of cast iron to be filtered, generally 10ppi for ductile iron; 20ppi for gray cast iron; 30ppi for malleable cast iron; The filtration area is determined by the weight of the filtered cast iron.

① Filter metal liquid inflow surface, straight runner design for open system. Effective use of filter area;
② The filter has a suitable gap. When it is placed, the filter can prevent rubbing sand with the side of the sand mold and pressing sand together with the box to prevent falling scattered sand particles from being brought into the mold;
③ The metal outflow surface of the filter should be left with a supporting width of ≥5mm, which effectively plays the role of pouring pressure support during pouring.

① Effectively filter impurities and improve the purity of liquid metal;

② Reduce the turbulence, make the liquid metal filling stable, uniform distribution of casting structure;

③ Reduce casting defects, improve surface quality and yield, which is conducive to cutting and reducing manufacturing costs.
