Structure.
Background technique
Aluminium is as important underlying metal material, and from since the establishment of the nation, under the vigorously supporting of country, aluminum i ndustry realizes height
Speed development.After replacing the U.S. to become the world's largest Aluminum Electrolysis Production state from China in 2001, aluminium yield is always maintained at the world the
One.And it is opposite with high yield be that bauxite resource is more nervous, while " high energy consumption " and " high pollution " of aluminium industry, also seriously
Constrain the development of aluminium industry.In recent years, electrolytic aluminium production capacity western part is shifted or is shifted to coastal area, the factory site of electrolytic aluminium factory
The mountain area or long and narrow coastal area that landform height rises and falls are transferred to from plains region.Conventional electrolytic aluminium factory rectifier and electrolysis
The arrangement form in workshop is relatively simple, in some regions with a varied topography, cannot preferably, flexibly adapt to factory site landform and want
It asks.
Summary of the invention
