Ceramic Foam Filter Ps Group Russia effectively removes large inclusions in molten aluminum, adsorbs micron-sized particles of fine inclusions, and plays a role in improving surface quality, improving product performance, improving microstructure, and increasing yield.

Ceramic Foam Filter Ps Group Russia can improve the fluidity of molten aluminum. Refers to the ability of alloy liquid to fill the mold. The fluidity determines whether the alloy can cast complex castings. Eutectic alloys have better fluidity in aluminum alloys.

From casting to solidification, the casting alloy liquid will show macroscopic or microscopic shrinkage in the later solidification zone. This kind of macroscopic shrinkage caused by shrinkage is visible to the naked eye, and it is divided into concentrated shrinkage and scattered shrinkage.
The concentrated shrinkage cavities are large and concentrated in diameter, distributed on the top of the casting or the hot section with thicker section. The dispersive shrinkage cavities are scattered and small, most of which are distributed in the casting axis and hot joints.
The micro-shrinkage cavities are difficult to see with the naked eye, and most of the micro-shrinkage cavities are distributed under the grain boundary or between the dendrites of the dendrite.

In November 2007, RUSAL signed a cooperation agreement with Samruk-Energo, a subsidiary of Samruk-Kazyna, to establish a 50/50 joint venture to operate Bogatyr Komir LLP, the largest coal mining company in Kazakhstan.

In April 2008, it acquired a 25% plus 1 share of Norilsk Nickel from Onexim, the world’s largest producer of nickel and palladium.

Due to a series of mergers and acquisitions, especially the acquisition of Norilsk Nickel, the debt level of UC Rusal is very high, which was exacerbated by the outbreak of the global financial crisis in 2008. In order to be able to retain its shares in Norilsk Nickel, and to avoid floating shares to foreign lenders, UC Rusal obtained a US$4.5 billion loan from the Russian State Bank VEB to repay foreign creditors’ debts.

As part of the debt consolidation work in 2009, UC Rusal reduced its operating costs by 25%. In December 2009, the company reached a final agreement to refinance US$17 billion in debt with 72 Russian and international lenders.

In January 2009, Oleg Deripaska was appointed as the CEO of Rusal, succeeding Alexander Bulygin, who had held the position for three years.
