Ceramic foam filter with polyurethane foam as a carrier to fill a ceramic slurry made of refractory materials, refractory aggregates, adhesives and other fine powders and water, and then compact the slurry.<\/strong>
\nMaterial cer\u00e1mico que recubre la fibra de espuma.
\nAfter drying, curing and tempering at high temperatures, the polyurethane is thermally decomposed, leaving behind foam ceramic products, namely ceramic floor filters.<\/p>\n

The ceramic material used to filter molten metal has a high melting point and will not melt during the casting process, nor will it decompose into molten metal.<\/p>\n

The filtration mechanism of Ceramic Foam Filter Iralco Aluminium<\/strong>
\nfilter
\nJust like a sieve, it can prevent foreign particles and aggregates larger than the pore size of the filter surface from passing through.
\nFilter cake
\nAfter sieving, many inclusions larger than the filter hole are trapped at the end of the filter inlet.
\nAs the number of trapped inclusions increases, a large inclusion cake is formed on the surface of the inlet end of the filter.
\nThe “filter cake” thins the liquid and makes the components smaller than the filter pore size stick to the “filter cake” to a certain extent.
\nFiltraci\u00f3n en lecho profundo
\nInside the ceramic foam filter, the flow path of the melt is tortuous, even in a small local area, there is a cross-flow phenomenon. This mainly plays two roles:
\n1. The possibility of particles coming into contact with the filter.
\n2. Change the flow rate and flow direction of the melt faster, so that the fine components in the melt are impacted and intercepted by the slag filter, straight holes (sieving), foam ceramic filter, filter cake left in the corner, and deep filtration.

La producci\u00f3n de lingotes de aluminio de I aument\u00f3 en 23% con respecto al mismo periodo del a\u00f1o anterior en los primeros siete meses.<\/strong><\/p>\n

I\u2019s aluminum ingot production has increased by 23% in the first seven months of the current Iian calendar year (March 21 to October 22). Compared with the same period last year, I\u2019s Mining and Mining Industry Development and Reform Organization (IMIDRO) announced.<\/p>\n

The country\u2019s seven-month aluminum ingot production was 305,101 tons, compared with 247,335 tons in the same period last year.<\/p>\n

As previously announced by the Iian Mining and Mining Industry Development and Reform Organization, compared with the previous year’s figures, I’s aluminum ingot production increased by 61% during the previous Iian calendar year 1399 (as of March 20).<\/p>\n

El a\u00f1o pasado, la producci\u00f3n nacional de lingotes de aluminio fue de 446 800 toneladas.<\/p>\n

En el a\u00f1o natural 1398, los principales productores de aluminio de I fabricaron con \u00e9xito 278 318 toneladas de productos.<\/p>\n

Compared with the previous year’s figures, the country’s aluminum ingot production in I in 1398 fell by 8%.<\/p>\n

According to data from I\u2019s Mining and Mining Industry Development and Reform Organization, among the country\u2019s largest producers, I Aluminum Corporation (IRALCO) produced 185,000 tons of aluminum ingots last year, the best performance.<\/p>\n

In the last month of the previous year (February 19 to March 20), the national aluminum ingot production reached 41,000 tons, an increase of 38% from the 30,000 tons in the same period last year.<\/p>\n

By the end of the current Iian calendar year (March 20, 2022), the country’s annual aluminum ingot production<\/a> is planned to increase by 63%.<\/p>\n

El a\u00f1o pasado, durante la inauguraci\u00f3n del mayor complejo de producci\u00f3n de aluminio de Ir\u00e1n (situado en la zona central de la provincia de Fars), el exministro de Industria afirm\u00f3 que se espera que la producci\u00f3n de aluminio del pa\u00eds se duplique una vez que la planta entre en funcionamiento.<\/p>\n

Officials said that the output value of I’s mining industry is about 22 billion U.S. dollars, saying that the country’s minerals are relatively self-sufficient and there are large exports every year.<\/p>\n
