1.Description
Silicon carbide foam ceramic filter using German imported polyurethane foam sponge as a carrier, silicon carbide mainly squeezed into the foam sponge, and then squeeze out the slurry,the slurry around the foam fiber, after drying, baking at high temperature, polyurethane thermal decomposition, leaving foam ceramic products, namely silicon carbide foam ceramic filter. The silicon carbide foam ceramic filter, with the three- dimensional mesh interconnection structure of foam sponge, can make metal liquid reflect rectification, mechanical screening, filtration cake, adsorption and other filtration mechanisms to effectively improve the purity of metal liquid, reduce waste rate, reduce mechanical processing loss, thus improve production efficiency and reduce production cost. Silicon carbide foam ceramic filter has high strength, good thermal stability, larger than surface area and high size accuracy. It is mainly used to filter and purify the filtration of ductile cast iron, ash cast iron,aluminum, copper and other alloy metal liquid, effectively remove large inclusions in metal liquid, adsorb smell magazines, reduce the content of gas and harmful elements in metal liquid, improve the metal matrix organization, and improve the mechanical properties of castings.
2.Function
They are constructed of impregnated foam in a controlled open-pore structure to provide a superior filtration effect. We provide an efficient solution for the removal of oxides and non-metallic particles from a broad range of non-ferrous metals.
3.Benefits offered
*Increased Fluidity
Removal of inclusions makes the metal more fluid, resulting in easier mold fill, better cast structure, and better thin section castability.
*Reduced Mold and Die Wear
Removal of inclusions and other nonmetallic debris from the melt reduces die soldering and mold-metal interaction, which degrades the mold surface and service life.
*Longer Tool Life
Oxide as well as intermetallic inclusions create "hard spots" that damage tools in machining and finishing operations. Filtration reduces tool wear and increases productivity.
*Fewer Rejects
Inclusions nucleate porosity, create hot tears during solidification,cause surface defects that mar appearance, and often reduce mechanical properties. In many cases, filtration cuts rejects from such causes to virtually zero. Improvements in yield to near 100% and reduced reject rates to at or near 0% are common.
