Ceramic Foam Filter Volkhov Aluminium, Foundry Filter

Ceramic Foam Filter Volkhov Aluminium can effectively filter out large inclusions in molten aluminum and small suspended inclusions as small as tens of microns through three filtering and purification mechanisms: mechanical retention, scum rectification and deep adsorption.

With the efforts of many foundry workers and researchers, the application of Molten Aluminum Filter has been greatly developed.
However, it has high strength, high porosity, good thermal shock resistance and corrosion resistance to molten metal.

Ceramic Foam Filter Volkhov Aluminium is widely used in the aluminum casting industry.

With the development of science and technology, industrial production has higher and higher requirements for the purity and quality of aluminum and its alloy materials.
The traditional refining and degassing process cannot remove the fine suspended non-metallic inclusions in the molten aluminum.
Therefore, many purification methods have been studied. According to its different mechanisms and forms, purification methods can be divided into adsorption purification, physical purification and filtration purification.

30ppi 40ppi Foundry Filter is the most commonly used ceramic foam filter in the aluminum casting industry.
Ordinary aluminum casting usually uses 10-40ppi ceramic filter plates.
Aviation and high-quality aluminum materials usually use 30-60ppi ceramic filter plates.

Rusal’s domestic market and China sales director Roman Andrewshin said that Rusal exports about 3 million tons of aluminum each year, and this year may reduce exports by hundreds of thousands of tons of aluminum because the taxation will make some exports unprofitable.

The Russian government announced in June that it would impose a tariff of at least 15% on exports of steel, nickel, aluminum and copper from August 1 (the tax rate varies) to stabilize commodity prices and increase taxes. The government stated that the tax increase will continue until the end of the year and is a temporary tax collection, after which it will seek more sustainable measures.

Andrewshin said that the taxation is unfair, because Rusal will invest billions of dollars to modernize the smelter, and the taxation will not significantly reduce local prices, because aluminum accounts for a relatively small share of Russian construction costs. Rusal is unlikely to pass on tax costs to customers, partly because it cannot incorporate taxation into most of its long-term agreements. The tax may mean that Rusal considers idle some unprofitable production lines, and its new Taishet project may increase production more slowly than previously expected.

At the same time, Rusal expects aluminum demand to remain strong and prices may rise, although it may not reach historical highs of more than US$3,300 per ton. Due to the recovery of the global economy from the epidemic, China’s measures to restrict supply, and the prospect of increased demand in the electric vehicle and solar industries, aluminum prices have risen by about 23% this year.
