Sic Ceramic Foam Filter for Steel Iron Foundry
Product Description
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 celsius degree 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: 1500 celsius degree
Pore Size: 10,20,30,60 PPI
