12 8月 Ceramic Foam Filter Ural Aluminium
Ceramic Foam Filter Ural Aluminium can effectively remove various oxidized inclusions produced in the aluminum smelting process through physical adsorption and chemical action, thereby reducing casting defects and improving casting quality.
The selection of Ceramic Foam Filter Ural Aluminium specifications depends on the melt flow rate and total flow. If the flow rate is large, the total throughput is large, and the pore size of the filter plate is small, a larger size is used. When purchasing filter materials, the effective specific surface area or porosity calculation of the foam should be carefully evaluated.
Observe the uniformity of the mesh on the surface of the filter plate, and then observe the uniformity of the mesh on the section of the filter plate.
The history of the development of RUSAL
The company continued to expand its raw materials and production bases: it acquired a controlling stake in Eurallumina (Italy), a cathode plant in Shanxi, China, a controlling stake in Aroaima Mining Company (Guyana), and a controlling stake in the Boksitogorsk aluminum smelter. In December 2006, Rusal launched the Khakas aluminum smelter, the industry’s first production facility built in Russia after a 20-year hiatus.
After the merger of RUSAL, SUAL and Glencore (Switzerland), the joint company RUSAL was established, which is the world’s largest aluminum producer. RUSAL started to implement two main projects: the construction of the Boguchansky aluminum smelter and the construction of the Taishet aluminum smelter.
RUSAL bought more than 25% of Norilsk Nickel, which is the world’s largest producer of nickel and palladium and one of the largest producers of platinum and copper. The company subsequently cooperated with Samruk Holdings to set up a joint oil exploration company operating in Kazakhstan’s Ekibastuz coal deposit, and purchased a cathode assembly manufacturing plant in China, Taigu Cathode. In Nigeria, Rusal started production at the ALSCON plant.
During the global economic crisis in the late 2000s, the company encountered some serious difficulties. The demand for aluminum plummeted to historical lows and the price also fell, which naturally caused a major blow to the company’s financial situation and led to tensions with creditors. A series of measures aimed at cutting costs, optimizing production and reducing production costs have enabled the company to survive the crisis with minimal losses, while laying the foundation for further business development and diversification. From October 2009 to December 2009, Rusal signed a number of agreements with Russian and foreign banks, restructuring debt totaling US$16.8 billion. As a result, the company’s debt to many foreign banks amounted to $7. 4 billion underwent a four-year reorganization, with the option to extend the transaction for another three years. A total of 70 credit institutions participated in the restructuring transaction and revised approximately 50 loan agreements.
Despite the problems encountered during the crisis, in July 2009, RUSAL successfully completed the environmental modernization of the Krasnoyarsk aluminum smelter that started construction in 2004. The final stage of the project is to start a new gas processing center, using a new dry gas scrubbing method.
RUSAL shares are listed on major stock exchanges in the world and Russia: Hong Kong Stock Exchange, Paris and NYSE Euronext, MOEX and RTS.
The company began to cooperate with the Hong Kong University of Science and Technology, focusing on joint research and development, knowledge and experience sharing between professors and students of Russia and Hong Kong University.
