Description

Foam Ceramic Filter is just developed as a new type molten metal filters to decrease casting flaw in recent years. Foamed ceramics have the characters of light weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, chemical corrosion resistance and high temperature stability in molten metal. With the distributing pores net structure, they are able to increase the surface areas, and absorb the sinter, the liquid metal becomes more pure, waster quality problems such as sand pore and air pore are much less. and the cast quality becomes much better.

Get rid of the impurity, refractory scrap, solid refractory alloy, sinter, in the
molten metal liquid when casting the products, get rid of turbulent flow, reduce the air cavity of castings, raise the quality of cast. So our ceramic foam filters (foamed ceramics) are widely used in the foundry industry such as casting /foundry of low carbon steel, stainless steel , iron, bronze, copper, alloy and aluminum for preventing defects caused by oxides, dross, gas, slag and other impurities. Alumina Foam Ceramic Filters Zirconia Foam Ceramic Filters SiC Foam Ceramic Filters, Ceramic Foam Filters.

Advantages:
1. Eliminates turbulence in the metal stream, smoothes out metal flow, avoiding
sprays, splatter and backset. Improve fluidity, castability, machinability, yield,
2. Remove a much greater fraction of fine particulate, Reduce rejects and rework,
Low-pressure loss.
3. Provides consistent flow rate and capacity.
4. Various sizes, shapes and pore sizes are available.

Types of Inclusions and Their Origins
Inclusions show up as alumina, silica, intermetallic sludge compounds, and other refractory and ceramic hard particles. The come from many sources: dirty charge materials, tools, ingot, oxides, foundry sand debris on returns metalworking lubricant pigments from trim, gates and risers, machined scrap castings refractory wear debris from furnaces, ladles, and other molten metal handling vessels oxidation of aluminum, magnesium, and other reactive alloy elements in the melt itself sludging in die cast. alloys (precipitation of intermetallic compounds at lower temperatures) fluxing salts and/or other metallurgical additives Good furnace practice helps minimize the generation and entrapment of inclusions, but good practice alone often is not enough. You usually need effective filtration to ensure quality.

Item 1: Foam-SiC (Silicon Carbide Ceramic Foam Filter)
Silicon carbide is thermally conductive (ceramic foam filters are insulating oxide ceramics). Therefore, there is less temperature gradient between the hot and cold sides of the filter. This means less superheat is required in the hearth, and less sludging occurs because temperature can be maintained in the dip-out well. Actual temperature gradients depend on furnace design, well area, metal throughput, and filter cleanliness.
Gradients less than 5℃ exist with steady metal flow - for example, during continuous dip-out, ladling, or pouring - and when oxide buildup, which is insulating, is removed periodically.

Applications: Filters for Molten Iron & Alloy, nodular cast iron castings, grey iron, castings and malleable castings,and for the filtration of non-ferrous metals.

Material: SiC (Silicon Carbide)
Working Temperature: ***0℃
Pore Size: *0,*0,*0,*0 PPI

Item 2: Foam-Zr (Zirconia Ceramic Foam Filter)
Applications: Filters for Molten stainless Steel, Alloy steel& other metal in
precision molding.
Material: Zirconia(ZrO2)
Working Temperature: ***0℃
Pore Size: *0,*0,*0,*0 PPI

Item 3: Foam-AL (Alumina Ceramic Foam Filter)
Applications: Filters for Molten Aluminum & Alloy: (aluminium oxide)

Material: Alumina (Al2O3)
Working Temperture: ***0℃
Pore Size: *0,*0,*0,*0 PPI

Item 4: Foam-Mg (Magnesia Ceramic Foam Filter)
Due to magnesium alloy is more active than a lot of other nonferrous metal, molten magnesium alloy can easily react with the SiO2, Al2O3 and liquate alumina ceramic filter rapidly. so that alumina ceramics is unable to filter magnesium alloy. We have successfully produced magnesia foam ceramic filter to meet the need of magnesium alloy recently.

Material : MgO
Applications: specialized for the casting filters of magnesia alloy.
Product Selection
1) Select suitable temperature filter according to kinds of alloy, the filter should
not exceed temperature and damage.
2) Select suitable bore density, purification is fit in with quality of casting.
3) Select dimension of suitable filter, not increase time of moulding.
4) Reduce the second dreg.
5) Porosity: filter ****0% when founding
