4 de enero Filtro de espuma cerámica con espuma de poliuretano como soporte
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.
Material cerámico que recubre la fibra de espuma.
After drying, curing and tempering at high temperatures, the polyurethane is thermally decomposed, leaving behind foam ceramic products, namely ceramic floor filters.
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.

The ppi number in the front indicates the hole density of the product. If the model is 10ppi, it means that the uniformity of pores per 25.4mm length is 8-12.

filter
Just like a sieve, it can prevent foreign particles and aggregates larger than the pore size of the filter surface from passing through.
Filter cake
After sieving, many inclusions larger than the filter hole are trapped at the end of the filter inlet.
As the number of trapped inclusions increases, a large inclusion cake is formed on the surface of the inlet end of the filter.
The “filter cake” thins the liquid and makes the components smaller than the filter pore size stick to the “filter cake” to a certain extent.
Filtración en lecho profundo
Inside 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:
1. The possibility of particles coming into contact with the filter.
2. 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 producción de lingotes de aluminio de I aumentó en 23% con respecto al mismo periodo del año anterior en los primeros siete meses.
I’s 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’s Mining and Mining Industry Development and Reform Organization (IMIDRO) announced.
The country’s seven-month aluminum ingot production was 305,101 tons, compared with 247,335 tons in the same period last year.
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).
El año pasado, la producción nacional de lingotes de aluminio fue de 446 800 toneladas.
En el año natural 1398, los principales productores de aluminio de I fabricaron con éxito 278 318 toneladas de productos.
Compared with the previous year’s figures, the country’s aluminum ingot production in I in 1398 fell by 8%.
According to data from I’s Mining and Mining Industry Development and Reform Organization, among the country’s largest producers, I Aluminum Corporation (IRALCO) produced 185,000 tons of aluminum ingots last year, the best performance.
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.
By the end of the current Iian calendar year (March 20, 2022), the country’s annual aluminum ingot production is planned to increase by 63%.
El año pasado, durante la inauguración del mayor complejo de producción de aluminio de Irán (situado en la zona central de la provincia de Fars), el exministro de Industria afirmó que se espera que la producción de aluminio del país se duplique una vez que la planta entre en funcionamiento.
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.
