【正文】 rmation benefits that year, created favorable conditions for aluminum through South. Second, effectively control the investment. Project is subject to a scientific approach to bidding, bidding to make savings of 20 million Yuan, in the implementation process of the project, every domestic prices of steel, cement and other building materials, the old buildings on the base encountered great difficulties in dealing with significant increase in the volume of civil engineering, but through rationalization and optimization, project control in fixed investment of 350 million Yuan. Third, environmental energysaving effect of the project. Project investment of nearly 30 million Yuan, using large prebake technology and aluminum oxide dense phase and hyper dense phase conveying technology, fluoride and other harmful gases purification efficiency of up to 98%. Compared with Soderberg cell before the modification, power consumption can be reduced by 1500 tons of electrolytic aluminum, and project environmental protection and energy saving effect is obvious. Four are in a relatively short period of time to the normal production. After four months of efforts, a project has put into operation all the 54 240KA large cell into regular production, stable current channel conditions and all the economic indicators are good, current efficiency in October had reached 93%, is close to and reach the domestic advanced level. In the case of production half of the cell, this ef
