Product Description

Ceramic foam filter is just developed as a new type of molten metal filters to decrease casting flaw in recent years. It is made from high quality ceramic materials, whose main components are Al2O3, Sic, ZrO2, MgO etc. Ceramic Foam Filter has 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...

We can supply ceramic foam filters are as follows:
*Silicon Carbide Ceramic Foam Filter is applied to purge and filter solution of ductile iron casting, grey iron and other iron casting.
*Zirconia Ceramic Foam Filter is applied to purge and filter solution of steel high temperature metal such as steel alloy stainless steel etc.
*Magnesia Ceramic Foam Filter is applied to purge and filter solution of magnesium and magnesium alloy.
*Alumina Ceramic Foam Filter is applied to purge and filter solution of aluminium and aluminium alloys

Ceramic Foam Filter are widely used in metallurgy and casting industry for the filter of melted metal with the main advantages as followings:
*good work strength under high temperature, good thermal shock resistance and melted metal inflow resistance
*high strength under room temperature, mechanic push resistance obvious filter effect
*ease the uneven inflow of casting, smooth the casting process, avoid surface defect
*have a large and even melted inflow rate
*good chemical stability, not affected by of melted meta, no change in its chemical compound
*precise dimension and can be used in production line automatic filter mounting equipment

Foamy ceramic filter is an advanced product for secondary refining. It has a network of porous structure. With the fluid inclusions continuous deposition, the mesh and channel size becomes smaller and smaller, which improves the effect of filtering. In addition, the filter plate is of high strength and can withstand certain pressure of the liquid metal and metal flow impact, but it is also fragile. The filtering effect is excellent due to its sophisticated structure, uniform quality and large surface area.

High porosity, heat and shock resistance, high intensity, high specific surface area and good stability, seiving, capturing slag and nidation. Besides filtering molten metal with high temperature, our products can be used as dealing with high temperature gas, catalyst substrate, solid heat exchanger, special packing and so on.
