China SIC Ceramic Foam filter For metal filtration Suppliers, Factories
SIC Ceramic Foam filters are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance,SIC 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.
What is the maximum working temperature of Silicon Carbide Ceramic Foam Filters?
The maximum working temperature for Silicon Carbide Ceramic Foam Filters is ≤1540°C, offering excellent stability in high-temperature environments.
What are the primary applications for these ceramic foam filters?
They are primarily used for molten metal filtration in cast iron, cast copper, cast bronze, and cast brass, as well as in high temperature gas filtration, chemical fillings, and catalysis carrier applications.
What is the typical SiC content in the chemical composition?
The Silicon Carbide (SiC) content is maintained at ≥62.00%, ensuring high refractory performance, corrosion resistance, and structural strength.
How resistant are these filters to thermal shock?
The filters exhibit robust thermal shock resistance, capable of withstanding rapid transitions from 1200°C to room temperature up to 3 times without failure.
What porosity and volume density can be expected?
These filters feature a high porosity rate of 80% to 90% and a volume density ranging between 0.3 and 0.5 g/cm³, optimizing flow rate while capturing impurities.
Can custom dimensions be provided if standard sizes do not fit?
Yes, beyond the standard round (e.g., 40x11mm to 305x25mm) and square (e.g., 40x40x11mm to 150x150x22mm) dimensions, custom shapes and sizes can be produced upon request.
