In order to ensure that southern company's "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 leadership of all the staff in the company's 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 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, installation, commissioning, guarantee engineering quality under the premise, on the production side transformation under difficult conditions, created the national industry's fastest speeds. II 32 large prebaked electrolytic cell on November 7 has been installed, marks has an annual production capacity of 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 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 energy-saving 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 effect can be achieved and better level in the industry. 50,000 tons of electrolytic modification process, from preliminary study to equipment selection, cost control, 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 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 ...
Four outstanding works. They are derived from their own inner feelings. I also sent a student to attend the class Department speech contest, failed to get a good result, but also actively cooperate with the Department and class activities! in order to create a demonstration dorm room, our weekly class to every bedroom check, where proposed is insufficient. In order to clean up the bedroom, we use the brush brushes a bedroom again. For the class out of a force. In the event we, many projects did not get the desired results. But we understand that we tried, and in the struggle. Also has made good progress in many of the! in my class the work carried out and the results achieved, thanks to the concern and support of the Department, thanks to instructor teacher's good, proper guidance, thanks to 46 students in the class will work closely together, to work together. Of course, we also have our weaknesses, needs to be further correction in their future learning and life, with a
view to achieving greater results. Five declarations of good party branch "branch is a fortress, a party member is a banner". Fighting in the railway engineering construction Group Headquarters Headquarters branches, a total of members 18. Role of the Xiang-GUI railway and tight South Lebanon railway, heavy, poor conditions of disadvantage, the branch closely around the construction work. Holding high the flag of our party members, unite and lead staff on the difficulties, overcome difficulties, take the zhengyou, a job well done and an engineering task, won the highly valued by leaders at all levels. Since October last year since the project began, Headquarters Branch is tightly around the center of its activities. Face South, climate is wet, sooner or later temperature larger, specific difficult, I branch from thought requirements all workers active motivated, do can long-term hard, dare fight of spirit prepared, while requirements all members lead, encouraged colleagues Zhijian each
other help, each other learning business knowledge, overcome temporarily difficult, active into to engineering official starts of the prepared work in the to, play out has as a branch of fighting fortress role and members of pioneer model role.
