Product Description

The basic materials of the ceramic foam filter are three kinds silicon carbide, zirconium oxide, and aluminum oxide. Silicon Carbide Ceramic Foam Filters have excellent strength and high-temperature impact resistance and chemical corrosion. It can withstand high temperatures up to about 1560 °C. They are therefore suitable for the casting of all copper alloys and cast iron.

The foam ceramic filter has an excellent filtering effect on copper water or aluminum water and utilizes a three-dimensional structure to effectively remove oxide inclusions and other non-metallic inclusions by blocking capture adsorption.

Whether it is gray iron, ductile iron or shaft body, cylinder or complex large parts, precision metal parts are filtered, and the product quality will get satisfactory results.

FEATURES
Silicon carbide foam ceramic filters are used in the production of ductile and grey iron castings, effectively trapping non-metallic inclusions in the metal stream. The resulting improvements are lower scrap, increased yield, mechanical properties, good finish, and machinability.

1. Reduce the defect rate of the inclusion of the defective products, and reduce the defect of the inclusion of 50% or more.
2. Improve the processing performance of the casting: the tool life is improved by more than 30%
3. Improve the mechanical properties of casting: mechanical properties increased by more than 10%.
4. Improve casting technology production rate: the rate of production rate increased by more than 10%

Silicon Carbide Ceramic Foam Filters Application
The foam ceramic filter is also suitable for copper alloys such as copper, bronze, brass, etc., to reduce the turbulence of the copper liquid and to rectify and purify the molten copper liquid.

Particularly valuable is that the copper castings that have been purified by filtration have a significant life extension in high-demand or harsh environments such as turbines and chemical parts of marine vessels, and have good effects on cast copper parts with surface polishing requirements.

Foam ceramic filters also play an important role in the traditional copper industry electric and electronic copper industry and continuous casting and rolling processes.

Since copper and alloys, including zinc alloys, have a greater specific gravity and produce greater thermal shock during casting, the use of silicon carbide foam ceramic filters in the copper casting process is generally strictly sized.


The placement of the ceramic foam filter in the gating system

silicon carbide ceramic foam filter is characterized by high porosity, mechanochemical stability, and excellent resistance to thermal shock and corrosion from molten metal. It can effectively remove inclusions, reduce trapped gas, and provide laminar flow when iron molten metal is filtrated, ceramic foam filter is machined to tight dimensional tolerance during production, this combination of physical properties and precise tolerance makes the first choice for iron molten metal filtration. The filter is generally installed in the gating system: Bottom of the sprue, runners, ingate, and pouring cup. Round filters are more commonly used in direct pour applications located inside an insulating or exothermic feeder sleeve, with optimum feed characteristics achieved when the filter is allowed to float after pouring.
