Filtro de circonio<\/strong><\/p>\n

Zirconia Filter is a type of ceramic filter plate. The zirconia-based ceramic slurry is uniformly applied to the three-dimensional network structure and the organic foam of the communicating pores as a skeleton of the carrier, and then dried and solidified and then fired at a high temperature.<\/p>\n

Los materiales b\u00e1sicos del filtro de espuma cer\u00e1mica<\/a> son tres tipos de carburo de silicio, \u00f3xido de circonio y \u00f3xido de aluminio.
\nThe basic material of the zirconia foam ceramic filter is zirconia ZrO2.<\/p>\n

Zirconium oxide ceramic filter has a maximum temperature of 1760 \u00b0C and is widely used in the filtration of various steel castings and large cast iron parts, high temperature mother alloys and aerospace castings, magnetic materials, copper-magnesium alloy continuous casting and non-ferrous metal alloy low-pressure casting.<\/p>\n

Zirconia Filter product effects<\/strong>
\n1. Efficient filtration to micron-sized slag, refractory fragments and other metal particle impurities, reducing tool loss during casting machining.
\n2. The molten metal is stable and the casting structure is uniform, thus improving the surface hardness, tensile strength and fatigue resistance of the casting.
\n3. The three-dimensional mesh structure has a good rectifying effect on metal turbulence, and has good control effect on non-metallic inclusions and secondary oxidation caused by turbulent erosion cavity.<\/p>\n

Zirconia Filter can make the aluminum liquid more evenly fill the cavity, and the molten metal has a higher tendency to turbulence during pouring.
\nThe turbulent flow through the three-dimensional pore structure of the zirconia foam ceramic filter is finally converted into a very stable laminar flow.
\nEl flujo laminar llena mejor la cavidad, lo que reduce la corrosi\u00f3n por impacto de la soluci\u00f3n met\u00e1lica en la cavidad de la pieza fundida y disminuye considerablemente la tasa de rechazos.<\/p>\n

How to use Zirconia Filter<\/strong>
\n1. Clean the UNIDAD DE FILTRADO DE TIPO PLACA<\/a>.
\n2. Coloca con cuidado la placa filtrante en la caja del filtro y presiona con la mano la junta de estanqueidad que rodea la placa filtrante para evitar que se derrame el aluminio fundido.
\n3. Precalentar uniformemente la caja del filtro y la placa filtrante para que alcancen una temperatura cercana a la del aluminio fundido. El precalentamiento sirve para eliminar la humedad y facilitar la filtraci\u00f3n transitoria inicial. El precalentamiento puede realizarse mediante calefacci\u00f3n el\u00e9ctrica o de gas. En circunstancias normales, dura entre 15 y 30 minutos aproximadamente.
\n4. Presta atenci\u00f3n a la variaci\u00f3n de la altura hidr\u00e1ulica del aluminio durante la fundici\u00f3n. La altura inicial normal es de 100-150 mm. Cuando el aluminio fundido comience a fluir, la altura hidr\u00e1ulica descender\u00e1 por debajo de los 75-100 mm y, a continuaci\u00f3n, volver\u00e1 a aumentar lentamente.
\n5. Durante el proceso normal de filtraci\u00f3n, evite golpear o hacer vibrar la placa filtrante. Al mismo tiempo, la canaleta debe estar llena de agua de aluminio para evitar que esta se agite en exceso.
\n6. Una vez finalizada la filtraci\u00f3n, retira la placa filtrante a la mayor brevedad posible y limpia la caja del filtro.<\/p>\n
