Filtro de espuma met\u00e1lica de aluminio fundido<\/strong> can filter micro-oxidized inclusions with good effect and low cost. Easy to use. Suitable for all kinds of molten aluminum and aluminum alloy.
\nthe result shows
\nThe yield rate of 3003 alloy printed boards increased by 9%
\nThe average weight between the broken ends of the 1145 alloy capacitor aluminum foil has increased by 45%
\nThe extrusion speed of 6063 alloy architectural aluminum profile is increased by 20%.
\nMetal Foam Filter does not have the function of removing hydrogen in the process itself. The filter plate needs to be replaced regularly, which is easy to damage and often brings trouble to production.<\/p>\n

The aluminum liquid filtration method mainly allows the aluminum melt to pass through a ceramic filter to separate the suspended solid inclusions in the melt. This method mainly removes inclusions in the melt, and has little effect on hydrogen removal.
\nTherefore, in practical applications, the aluminum liquid filtration method is often combined with the blowing method.
\nThe blowing method, also known as the bubble float method, is an aluminum melt purification process developed in the 1970s, which is particularly effective in removing hydrogen. Inert gas (such as nitrogen, argon, etc.) is introduced into the aluminum melt to form bubbles. The hydrogen in the melt diffuses into these bubbles under the effect of the partial pressure difference, and is eliminated as the bubbles rise, achieving the purpose of degassing. In the flotation process, the bubbles can also absorb some oxidized inclusions to remove impurities.<\/p>\n

Melting Aluminum Metal Foam Filter uses polyurethane foam as the carrier. After hydrolysis, the foam is immersed in paint made of ceramic powder, adhesives, sintering aids, suspension agents, etc., and then squeezed out the excess paint, so the ceramic coating is evenly coated on the carrier’s frame to form a green The body is then heated and dried.
\nThe ceramic foam filter separates the inclusions in the liquid casting alloy through three physical and chemical effects on the molten metal to achieve the effect of purifying the molten metal.<\/p>\n

Proof during use<\/strong>
\n1. The strength and service temperature of the sintered ceramic foam filter are higher than those of the same material-bonded ceramic foam filter, so its application range is wider, but the cost is also higher.
\n2. In similar filters, the higher the open porosity, the lower the bulk density and strength.
\n3. The order of the highest use temperature of the foam ceramic filter material<\/a> from high to low is partially stabilized zirconia-corundum-silicon carbide-mullite (high alumina bauxite). Partially stabilized zirconia is particularly suitable for various high-temperature alloys, corundum is more suitable for cast steel, silicon carbide is more suitable for cast iron, and mullite (high alumina bauxite) is more suitable for cast iron and non-ferrous metal alloys.
\n4. After the corundum ceramic foam filter is toughened by zirconia, the strength does not decrease, but the thermal shock resistance is significantly improved, which can expand its application range.<\/p>","protected":false},"excerpt":{"rendered":"
