Ceramic Filter Asahan Aluminium is the first key process that determines the application of aluminum alloy materials. It determines whether aluminum alloy materials have metallurgical defects and high-performance heritability, and dominates its application and development in various fields.
In casting and rolling production, the amount of melt filtration per unit time is small, and the flow rate is slow. Casting and rolling are mostly pure aluminum and soft alloys, and the green body is easier to purify. Generally, 50ppi and 30ppi two-stage ceramic foam filters are used. The thickness and area of the filter can be determined according to specific overflow calculations to meet the requirements.
Compared with casting and rolling, the production situation of castings is more complicated. The flow rate is large, and the filtering method of the filter is the same as that of casting production.
The filtering flow is equivalent to more than 253.5 times that of the pouring roller, which reduces the filtering effect.
In order to ensure the same filtration efficiency, the flow area of the filter should be increased to make the flow per unit area of the filter equal to it.
Secondly, in the duralumin and super-hard aluminum alloy melts, the possibility of containing fine slag particles is much greater than that of pure aluminum and soft alloys. Therefore, the filtration efficiency cannot be reduced, but it must be greatly improved in order to melt.
Asahan Aluminium introduced Ceramic Filter Asahan Aluminium is a product that achieves high purity. This product can be purchased through sales@adtechamm.com.
Therefore, it is best to use Ceramic Filter. It not only increases the filtration surface area in contact with the melt, but also reduces the flow rate per unit area of the melt. It ensures the filtration efficiency and flow rate. It can also reduce the filter pore size and increase the size of the filter to meet the production requirements. Porosity to improve filtration accuracy and reduce the number of residual fine particles in the melt.
Four aluminum rod factories in the Jombang Sumobito district of Indonesia were shut down. Why?
On January 22, 2021, four aluminum rod factories in Indonesia were seized by investigators from the Joint Law Enforcement Department of the Ministry of Environment and Forestry, Jabalnusra, Bali, Indonesia for handling the toxic and hazardous substance B3 (a type of aluminum slag waste) without permission.
The four aluminum rod factories that were seized were located in Bakalan Village, Jombang Sumobito District.
These four companies have been using B3 scrap (a type of aluminum slag) to produce aluminum rods since 2017, and the products are sold to household appliances and other industries.
The person in charge of the Ministry of Environment and Forestry explained: “The company that was sealed up used B3 waste in the form of aluminum slag without a B3 waste utilization permit, and dumped the remaining waste on the road, etc.”
According to relevant Indian laws, the heads of the four aluminum rod factories will be imprisoned for 1 to 3 years and fined between IDR to 300 million.
