Product Description

SiC ceramic foam filter

Silicon carbide ceramic foam filter is designed for filtering ductile iron, grey iron, and non-ferrous alloy castings. With excellent resistance to attack and corrosion from molten iron liquid, it can effectively remove inclusions in molten metal, and adsorbed impurities, reduce the molten metal in the gas and the harmful element content, decrease the reject rate, and improve the processing performance and mechanical properties of the casting.

Silicon carbide ceramic foam filter is designed for filtering impurities from molten iron & alloy, nodular cast iron castings, grey iron castings and malleable castings, bronze casting, etc. Which have high porosity (80%-90%), high thermal shock resistance, and large specific surface, compared with other traditional filters. It can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow when applied as filter in gating system.

Silicon carbide CFF Using Scope
Silicon carbide ceramic foam filter is widely used for molten iron and its alloys filtration in ferrous foundries also adapted to copper, bronze, brass, and other copper alloy filtering, and also applied in high-temperature waste-gas decontamination engineering.

• Quality Control:
• All production processes are carried out under the control of the ISO9001 quality management system. During the production process, first, ensure that the ambient temperature and humidity are within the required range. From raw material cutting, slurry forming, blank drying, and sintering, workers in each key process must In the process of self-inspection of the hole, size, weight, and appearance of the filter, the inspectors regularly conduct random inspections to ensure that defective products do not flow into the next process.
• Production inspection: self-inspection by production workers and regular sampling inspection by full-time inspectors. The finished products are fully inspected to ensure that qualified products flow into customers.
• After-sales service: If damaged during transportation, replenishment will be provided according to the situation. If the product is found to have quality problems during use, after both parties confirm that it is a problem with the filter, our factory will exchange or return the product.

Packing                                                 

1.  Inside packing: Filters are put in small boxes and Layered packaging. There is cardboard between each layer.
2. Outside packing: Cartons&Pallets. Three-layer corrugated cartons and export special pallets.
3. The mark on cartons can be designed according to the customer's request.
