1、Gay is now a provincial key construction project of aluminum Ltd-province with an annual output of 50,000 tons of technical innovation project of environmental protection and energy saving of electrolytic aluminum project manager. In this technological transformation projects, he has overall respons
2、ibility for the day-to-day affairs of the project. In order to ensure that southern companys control the scale of investment, strengthen field management, pay special attention to project progress, and ensure a successful operation, the overall goal. He and Engineering Department under the leadershi
3、p of all the staff in the companys technical command, on the difficulties and to overcome technical difficulties in the process, work hard, have made outstanding achievements, mainly reflected in the following aspects: first, careful organization and management achieved remarkable results. Technical
4、 innovation project of the year, started and completed a series of bids and completed to date, from production engineering to put into production after nearly a year, has achieved very significant results. A project first 56 slots from dismantling the old slot just 168 days, civil engineering, insta
5、llation, commissioning, guarantee engineering quality under the premise, on the production side transformation under difficult conditions, created the national industrys fastest speeds. II 32 large prebaked electrolytic cell on November 7 has been installed, marks has an annual production capacity o
6、f 50,000 tons of electrolytic aluminum production capacity of aluminum. Entire project almost 8 months earlier than planned, achieved the goal of production transformation benefits that year, created favorable conditions for aluminum through South. Second, effectively control the investment. Project
7、 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 inc
8、rease in the volume of civil engineering, but through rationalization and optimization, project control in fixed investment of 350 million Yuan. Third, environmental energy-saving effect of the project. Project investment of nearly 30 million Yuan, using large prebake technology and aluminum oxide d
9、ense 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
10、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 ef
11、ficiency in October had reached 93%, is close to and reach the domestic advanced level. In the case of production half of the cell, this effect can be achieved and better level in the industry. 50,000 tons of electrolytic modification process, from preliminary study to equipment selection, cost cont
12、rol, project progress, quality control and coordination among the various sub-projects and various professional, technical command under the correct leadership, both from an overall perspective, emphasis on integrity, and earnestly implement the relevant laws and regulations, strictly act according
13、to the contract. He tried to learn relevant knowledge, good style of business, operational and organizational coordination ability, project efficiency, quality and safety assurance system in place, with all units involved with the coordination and good . 暗挖隧道施工方案 环岛路（鳌山路-高殿二号）工程标环岛路（鳌山路高殿二号路段）工程标浅埋暗
