Filtro cer\u00e1mico de carburo de silicio<\/strong><\/p>\n

In casting production, steel castings, cast iron parts, cast aluminum parts and other alloy castings are prone to quality problems such as slag, blisters and gas eyes due to various reasons.
\nTherefore, the removal of non-metallic inclusions in the metal melt has great technical and economic value for improving the yield of castings and improving the quality of castings.
\nSilican Carbide Ceramic Filter removes bubbles, ash oxides, and various assimilated impurities in the aluminum melt, greatly advances the product rate of aluminum castings, the quality of the traveling aluminum products, and prevents other metal components from infiltrating into the aluminum solution. The shortcomings do not affect the aluminum alloy factor to ensure the quality of aluminum castings.
\nImprove the performance of aluminum casting machines: the hardness of the casting can be advanced, and the contour hardness is averaged and the bending strength of the casting is improved.<\/p>\n

Silican Carbide Ceramic Filter is widely used in various casting processes and production of various metal castings. It can effectively remove harmful inclusions in metal solutions, eliminate defects such as gas, scum, and blisters in castings, and reduce the rate of defective products. More than 90%, improve the intrinsic quality and appearance quality of castings, reduce energy and labor consumption, and significantly increase the economic and social benefits of casting manufacturers.<\/p>\n

Foam ceramic filter plates are available in a wide range of sizes and are suitable for use in all aluminum processing industries, such as electrolytic aluminum plants, strip processing plants, foil processing plants, tubular bar processing plants, and recycled aluminum ingot plants.<\/p>\n

La calidad del aluminio fundido es importante, ya que influye en gran medida en las propiedades de transformaci\u00f3n posteriores y en la calidad del producto final. Por ello, todos los pa\u00edses del mundo conceden gran importancia a la purificaci\u00f3n del aluminio fundido.
\nDurante el proceso de fundici\u00f3n, el aluminio queda expuesto a la atm\u00f3sfera del horno en estado fundido o semifundido, lo que lo hace propenso a la oxidaci\u00f3n; reacciona f\u00e1cilmente con el vapor de agua para absorber hidr\u00f3geno y forma con facilidad diversos tipos de escoria no met\u00e1lica (como restos del revestimiento del horno o cloro presente en el fundente). compuestos, carburos, etc.), as\u00ed como part\u00edculas intermet\u00e1licas gruesas y similares.<\/p>\n

Aluminium Ceramic Foam Filter production process<\/strong>
\nEl Filtro de espuma cer\u00e1mica<\/a> Utiliza una estructura de red tridimensional y una esponja de espuma org\u00e1nica unida a los poros a modo de soporte, en la que se introduce una pasta cer\u00e1mica especial con propiedades tixotr\u00f3picas, y se aplica la pasta cer\u00e1mica de forma uniforme sobre el esqueleto del soporte mediante un proceso especial de extrusi\u00f3n con rodillos. A continuaci\u00f3n, se seca y se solidifica, y finalmente se cuece a alta temperatura.
\nFiltro de espuma cer\u00e1mica porosa. Filtros de espuma cer\u00e1mica para aleaciones de aluminio. Desde que se iniciaron las primeras investigaciones en 1978, la tecnolog\u00eda de filtraci\u00f3n con espuma cer\u00e1mica ha experimentado un r\u00e1pido desarrollo.
\nPorous Ceramic Foam Filter uses polyurethane foam as a carrier, immersing it in a coating made of ceramic powder, binder, sintering aid, suspending agent, etc., and then extruding excess coating to uniformly apply the ceramic coating to the carrier. The skeleton becomes a green body, and the green body is dried and fired at a high temperature.<\/p>\n

Aluminium Ceramic Foam Filter transmittance<\/strong>
\nTransmittance refers to the effective filtration area of the foam ceramic filter plate product. The higher the light transmittance, the less blind holes are, and the more effective the filter holes (potholes), the better the filtering effect.
\nLa placa filtrante de cer\u00e1mica celular que se va a inspeccionar se coloca sobre una caja de luz con una bombilla incandescente de 200 W incorporada, y se utiliza la placa cuadrada de pl\u00e1stico transparente con una cuadr\u00edcula uniforme de 5,0 \u00d7 5,0 mm para medir el \u00e1rea de la superficie principal de la placa filtrante, con el fin de calcular el resultado de la prueba. La transmitancia de la luz de la placa filtrante se utiliza para determinar la transmitancia de la luz de la placa filtrante. En esta norma, se especifica que la transmitancia (proporci\u00f3n de orificios) de la placa filtrante debe ser de 95% o superior.<\/p>\n
