Maanshan Iron and Steel Co., Ltd. has produced 20 million tons of steel for the first time

Maanshan Iron and Steel Co., Ltd. has produced 20 million tons of steel platform for the first time. Maanshan Iron and Steel Co., Ltd. produced a total of 20.97 million tons of steel in 2020, an increase of 1.14 million tons over 2019 and a record high.

2020 is the first complete year for Maanshan Iron and Steel Co., Ltd. to be fully integrated into China's Baowu. 100 million tons of Baowu can not be achieved without the contribution of Maanshan Iron and Steel people. At the beginning of the year, the Manufacturing Management Department "took" back the task of producing 20 million tons of steel a year, which was accompanied by unprecedented pressure and challenges.

Pre-iron system

Everyone carries a heavy burden, and everyone has an indicator on his shoulder. As the "chief planner", the Manufacturing Management Department has formulated a plan of "the company's total hot metal output of 18.2 million tons and crude steel output of 20.2 million tons" and allocated it to the guarantee and production units one by one. In the process of plan implementation, the management mode of "daily tracking, weekly report and monthly summary" is implemented, and the process optimization control is carried out from the aspects of resource balance, variety planning and maintenance coordination, and each process is controlled in real time.

Blast furnace is the cornerstone of iron and steel production. In the face of the double impact of the epidemic and flood situation, the restriction of raw fuel in the third quarter, and many difficulties in the construction of key projects, the "three treatments" and the regulation of outstanding environmental problems, the ironmaking plant has achieved an impressive performance of "an average daily output of more than 41000 tons." overfulfilled the task.

Steelmaking unit

All production units seize the opportunity of local enrichment of hot metal to carry out high-yield training one after another, and strive to step onto a new production platform. "the steel mills have repeatedly broken records. Among them, the longwood division has the highest daily output of 13800 tons of steel, and the fourth steel mill has the highest daily output of 28500 tons of steel. " Yang Quanshan, deputy manager of the production management room of the manufacturing management department, told reporters. At the same time, Maanshan Iron and Steel Co., Ltd. takes further reduction of the ratio of iron to steel as an important starting point to increase steel output, repeatedly studies the smelting process, and actively does a good job in the coordination of the whole After full running-in, the double improvement of benefit and output has been realized. "the comprehensive iron-steel ratio of the company has been reduced to the historical best level of 0.887 and 0.878 after slag deduction." Mao Ming, manager of the sheet first room of the manufacturing department, said proudly, "since August, the monthly iron-to-steel ratio has set a new record, which has laid a solid foundation for the steelmaking level to a new level."

Rolling unit

Not only output, but also quality. In the process of rolling, the steel rolling unit has set up a special technical group to solve the difficult problem and break the bottleneck. Focus on the process control of the production process and product inspection standards, targeted innovation and transformation of the product process, to every detail to be stable and quality. At the same time, in order to cope with the increasingly fierce market homogenization competition, Maanshan Iron and Steel Co., Ltd. has made great efforts to develop more competitive products with higher added value and more complete varieties and specifications.

Public auxiliary system

Ring help, cohesion. The equipment Management Department and the Ministry of Transportation have done a lot of effective work in ensuring the stable operation of equipment and smooth supply of logistics to ensure the stability of raw material supply and production. The company's trade union organizes special labor competitions to fully stimulate the initiative, enthusiasm and creativity of front-line workers in production.

"this year, we will strive to produce 20.55 million tons of steel under the premise of overhauling the No. A blast furnace for 100 days." In the new year, the Manufacturing Management Department is moving towards a new goal.
