As a new type of inorganic non -metallic filtration material, foam ceramics have the advantages of light weight, high strength, high temperature resistance, corrosion resistance, simple regeneration, long service life, and good filtering adsorption. Foam ceramic filter is generally filled with foam sponge, and then squeezed out the slurry. The remaining ceramic materials covering the foam fiber are sintered at high temperature. The foam sponge is hotly decomposed. For foam ceramic filters, this filter can be used for various cast alloys based on different ceramic materials.
Silicon carbide ceramic foam filter The three -dimensional three -dimensional structure can fully reflect the four major filtering mechanisms of its rectification, mechanical screening, "filter cake", and adsorption when filtering melt metal. Remove or reduce the miscellaneous objects in the metal liquid to increase the purity of the metal fuse, so that the surface of the cast metal castings is smooth, the intensity is increased, the waste rate is reduced, and the processing loss of the machine is reduced, thereby reducing energy consumption, increasing labor productivity and labor productivity cut costs.

Found size range: 35x35mm-360x360mm.
Round size range: diameter 40mm-diameter 360mm.
Thick size range: 11mm-40mm.
The size tolerance can be controlled in the range of the upper and lower deviations of 2mm. Since the size of the filter's base or card slot size also has a tolerance, the filter size tolerance needs to be confirmed by the user.
Select the size and mesh of ceramic filter:
Consider the degree of metal liquid cleanliness and pouring temperature. Consider cast iron and water, calculate the current control area to meet the requirements of the casting time.Try to use an open casting system to avoid rolling air
Calculate the filter area according to the filtering ability and casting time requirements
Silicon carbide foam ceramic filtration capacity (KG /CM2): Gray Iron: 4.0 ball iron: 2.0 alloy cast iron: 1.0-2.0
Grid selection: General gray iron uses 20ppi and 10 ppi for ball iron. You can also choose 15 or 25PPI. The selection of mesh is related to the actual casting of various factors.
Place in the pouring cup: more commonly used for precision casting and iron mold sandwiching.
Placed at the bottom of the direct watering road: It is often used in the case where the whole box is lava iron water, especially suitable for the casting system that is located in the center of the casting and a variety of crossing roads.
The horizontal channel is placed on the horizontal channel: The metal liquid is stable, which avoids the direct impact of the metal liquid on the ceramic filter. It is better to play the slag blocking function of the upper half of the road, and it is convenient to place.
Placed vertically on the crossway: The metal fluid has a fast flow rate and has good charging capabilities. The metal solution directly impacts the surface of the ceramic filter. The impact ability of the ceramic filter should be considered.
Ceramic filter base or card slot design: It is necessary to fully consider the convenient placement of the filter (such as cone surface, slope, gap, etc.) and firm and reliable. The casting support surface at the placement should be made of round angle (wipe) The above support width filter is surrounded by 1-1.5mm gaps and sand grooves to prevent accidental falling on the surface of the scattered sand particles in the inner filter.

Precautions: You need to preheat. Ceramic filter is fragile. During transportation and use, you need to avoid fell, fall and barbaric operations during transportation and use; if you open the box and take the ceramic filter, you may produce some fine residue due to bumps or scratches. In front of the system, use compressed air to blow the pottery filters on each side, or flip on both sides with your hands, and gently throw away the fine residue adhesive on the surface. Storage: Put in a dry and ventilated place, the outer box should not be pressed, ceramic filter installation is installed After the box, do not stacked more than 7 layers of carton.
