    Product Description

    Silicon carbide foam ceramic filter using German imported polyurethane foam sponge as a carrier, silicon carbide mainly squeezed into the foam sponge, and then squeeze out the slurry,the slurry around the foam fiber, after drying, baking at high temperature,polyurethane thermal decomposition, leaving foam ceramic products, namely silicon carbide foam ceramic filter.

    The silicon carbide foam ceramic filter, with the three- dimensional mesh interconnection structure of foam sponge, can make metal liquid reflect rectification, mechanical screening, filtration cake, adsorption and other filtration mechanisms to effectively improve the purity of metal liquid, reduce waste rate, reduce mechanical processing loss, thus improve production efficiency and reduce production cost. Silicon carbide foam ceramic filter has high strength, good thermal stability, larger than surface area and high size accuracy.

    Product Features

    1.Structure: three-dimensional network structure, smooth rectification and filling The upper, middle and lower three-dimensional network has no blocked holes, no blind holes, reducing eddy current, flocculation laminar flow, and stable filling

    2.Filtration: Labyrinth channel, efficient mechanical slag blocking There are microscopic gaps, strong adsorption of slag, effective filtration, oxide inclusions, slag and other large impurities
    3.Performance: Large internal specific surface area of the filter The grout is sufficient and without blind holes, forming a complete multidimensional, three-dimensional channel of pore reinforcement, absorbing micro-inclusions

    Working Principle 

    The foam ceramic filter can be placed in various parts of the pouring system, and should be selected according to the
    characteristics of the parts and production conditions, as close as possible to the casting to achieve the best filtration effect.In practical applications, according to different castings and requirements, the following methods can be used:

    (1) Placed in the mold shell pouring cup: Reserve the filter table at the mold shell pouring cup, after the mold shell roasting,place the foam ceramic filter at the gate position, or bake and preheat the filter with the mold shell before pouring, which helps the metal liquid to begin to pass, and the use effect is better. In order to make the filter easy to place, it is necessary to design the filter base, that is, there is a 2 mm gap between the filter place and the outer edge of the filter in the shell, and the supporting surface should be left with a base greater than 5mm width.

    (2)Place the foam ceramic filter at the gate of the special ceramic material In the cup, during the shell making process, the
    pouring cup is connected to the casting, and the filter is placed in the pouring cup for pouring.

    (3) Place the foam ceramic filter in the pouring system, make the pouring system shell with the filter in advance, and reserve an opening in the corresponding position on the shell to facilitate the filter to be placed in the installation seat. The shell making stage is placed in the seat, sealed with water glass or silica sol, and can be poured test after curing and drying.

    Functions Of Ceramic Foam Filter

    ● Decontaminate the melting metal liquid
    ● Simplified gating system
    ● Improve the metallurgical structure of the castings
    ● Reduce imparities of the castings
    ● Improve casting quality rate
    ● Reduce casting internal re-oxidation defects 
    ● Reduce the surface defects after machining of the castings

    Other types for your choose

    Selection method:

    1, according to the use of temperature to select the appropriate filter type;

    2, according to the quality requirements of the casting and purification effect to select the appropriate hole density;

    3, according to the casting weight and pouring time to choose the appropriate size.
