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
