Ceramic Filters New Zealand Aluminum is a new type of filter with low density, high porosity and a three-dimensional network framework structure. It is widely used in the aluminum processing industry to filter molten aluminum to improve the quality of aluminum.
Ceramic Filters for New Zealand Aluminum Casting is the first cost-effective medium to remove non-metallic inclusions from molten aluminum. Ceramic foam filters are still the standard for aluminum filtration in foundries all over the world.
Mainly used in continuous casting equipment for aluminum and aluminum alloy melt filters, half-continuous casting, gravity casting, low pressure casting, and also used in other non-ferrous metal precision casting.
Due to its interconnected three-dimensional structure, the ceramic foam filter can fully reflect its four filtering mechanisms when filtering molten metal: rectification, mechanical sieving, “filter cake” and adsorption.
At the same time, the filter material has good chemical stability and does not react with the alloy liquid, thereby effectively removing or reducing the inclusions in the molten metal and improving the purity of the molten metal.
Ceramic Filters New Zealand Aluminum can effectively remove large inclusions in molten aluminum, absorb micro inclusions in particles, improve surface quality, improve product performance, microstructure, and increase output.
New Zealand government officials are optimistic that if aluminum prices remain high, the Tiwai Point aluminum smelter will continue to operate for a longer period of time. However, officials also warned that there is a risk because it will accumulate millions of tons of greenhouse gas emissions.
Southland, the southernmost region of New Zealand, has been adapting to survive, as the aluminum smelter will lose hundreds of jobs and increase spending when it closes at the end of 2024.
Update: “Although the power supply contract between NZAS and Meridian will expire in December 2024 and it will be closed at the same time, it is estimated that the smelter will continue to operate after that date. If the outlook is still positive enough for the aluminum market .”
However, many companies and iwi are exploring whether the Tiwai Point aluminum smelter can be used for green hydrogen production.
