Alumina Ceramic Foam Filter for aluminium casting filtration
1. Alumina Ceramic foam Filter is developed as a new type molten metal filters to decrease casting flaw in recent years. Foamed ceramics have the characters of light weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, chemical corrosion resistance and high temperature stability in molten metal. With the distributing pores net structure, they are able to increase the surface areas, and absorb the sinter, the liquid metal becomes more pure, waster quality problems such as sand pore and air pore are much less and the cast quality becomes much better.
ceramic foam filter provide the ultimate quality in molten metal filtration.They are constructed of impregnated foam in a controlled open-pore structure to provide a superior filtration effect. NINGXIN® filters provide an efficient solution for the removal of oxides and non-metallic particles from a broad range of non-ferrous metals.
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.
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.
