Capability of benchmarking collaborative management

Energy costs account for more than 30 percent of the total cost of the entire steel enterprise. In the face of the grim situation of the steel industry, advanced steel companies have placed the reduction of energy and power costs such as "water, electricity, wind, gas, and steam" in an important and prominent position.

The company seized the opportunity of Baosteel's comprehensive collaborative support work, learned Baosteel's "three-flow, one-state" energy management method, took energy and power cost as the general starting point, carried out an energy review, explored the space for energy and power cost reduction, formulated reduction targets, formulated improvement measures in accordance with the "five fixed" principle, and clarified the management process of statistics, analysis and evaluation. Promote the continuous improvement of energy and power costs, comprehensively improve the level of energy saving, cost reduction and efficiency, and sound the rallying signal of the "energy and power cost reduction war".

Against advanced enterprises, the company proposed a reduction target of more than 50 million yuan in energy and power costs in 2024, which made everyone feel unprecedented pressure.

"We must dare to deny ourselves, dare to look back, dare to look at ourselves, firmly establish a sense of ownership, not relying on, not talking about conditions, not talking about objective, give full play to the enthusiasm and initiative of all employees, and complete the goals determined by the company!" The company made it clear in the energy and power cost reduction meeting.

The orders are as high as mountains and the three armed forces are in command. The company takes the energy and power consumption per unit product of each process in 2023 as the benchmark value, benchmarks the best historical level and benchmark value level, and formulates the planned value of energy and power medium consumption of each process in 2024 in accordance with the principle of "lagging behind and catching up quickly, leading and seeking progress in stability, and pursuing extreme energy efficiency", and the 14 key process energy and power cost reduction targets are released. Specific work support measures have been defined, and a dual-dimension evaluation mechanism has been formed with index evaluation and management process evaluation as the core.

One target layer by layer decomposition to the workshop, to the unit, to the post personnel, the rapid development and implementation of fast-winning measures, energy-saving projects are rapidly promoted... An energy war around the "hydropower climate" has started in full swing.

Continuous innovation technology saving "energy"

The project achieved high quality and high use of gas, low quality and low use, gas consumption reduced by 65%. As a large energy consumer, steel mills actively promote the application of advanced energy-saving technology, strengthen process route optimization, for 11 kinds of energy media and different processes, furnace, clear converter gas recovery, LF power consumption and other 13 key control indicators for daily control, continue to improve the energy efficiency management system, set up energy efficiency work team, promote "extreme energy saving, extreme recovery" to take root.

Technical energy-saving renovation project is the fundamental way to save energy and reduce cost. By 2024, the company has completed the renovation and construction of 7 energy-saving projects, and achieved energy saving of 20,600 tons of standard coal. At the same time, the company learns from the experience of advanced enterprises, organizes all units to deeply study the necessity, feasibility and economy of application, prepares project proposals, and carries out grid ultimate energy efficiency diagnosis according to the principle of "horizontal to edge, vertical to end, vertical to end". All units continue to carry out comprehensive identification of energy power system in combination with the actual production. Continue to explore the space to reduce costs and increase efficiency. At present, the company has planned 67 energy-saving improvement projects, which are expected to achieve technical energy saving of more than 200,000 tons.

If a worker wants to do a good job, he must first sharpen his tools. Energy management "three points of technology, seven points of management, twelve points of data", the authenticity and comprehensiveness of data is extremely important to energy management.

In the intelligent control hall of the company, 18 screens constitute the strongest brain of the company's energy management, and various indicators such as gas system and steam system are presented on each screen, and the energy consumption of the company's various processes is clear.

The company makes full use of the management advantages of the full integration of manufacturing flow, energy flow and value flow, in accordance with the principle of "prediction, budget, prediction, pre-control" and maximum utilization of energy value, accurately carry out energy supply work, blast furnace gas zero release for 52 consecutive days, and key energy efficiency indicators such as converter gas recovery and tonnage steel surplus energy recovery have reached the best level in history.

The equipment management Department and the Environmental Protection Department shall strengthen the energy measurement management to ensure the accuracy, completeness and timeliness of energy data; Each process to strengthen the energy information collection equipment maintenance, to provide accurate first-hand materials; The equipment Finance Department and the Environmental Protection Department strengthen the verification of the authenticity of data statistics and accounting, and fully support the company's energy cost reduction and efficiency.

Accounting management technology to increase "energy"

Steel mills around a center, focusing on three directions, innovation of five types of measures, the implementation of "data", "normalization", "modeling", "intelligent" energy management. The recovery level of converter gas increased by 4.5% year-on-year, and the power consumption of steelmaking process decreased by 8.9% year-on-year, reaching the benchmark level of energy efficiency. The cost of energy and power decreased by 49 million yuan year-on-year, ranking first in the company.

◑ Iron plant energy management adhere to the scientific concept, learn to understand the operation law of giant blast furnace, reduce the fluctuation of furnace condition, take stability as the core, from "material" to "iron", the implementation of the whole process, the whole system and all personnel control, power cost has been reduced by more than 15 million yuan.

◑ The coking process adheres to the principle of "three grasp and one standard", strengthens lean management, optimizes production technology, adjusts the coal blending structure, and improves the level of coke oven gas recovery. Optimize the energy use structure, and significantly reduce the cost of energy and power.

◑ Each process of rolling line focuses on the reasonable matching, efficient utilization and ultimate recovery of energy flow and manufacturing flow to minimize consumption and achieve cost reduction and efficiency increase.

◑ The Ministry of Energy and Environmental Protection strengthened control over the cost process of energy and power, fully tapped the potential and space for energy conservation in the utilization of gas, and normalized zero discharge of gas from blast furnaces.

◑ In terms of the overall production organization, in order to realize the best path of energy operation, the production Department strengthens the control of production organization, ensures stable and balanced production, reduces the situation of waiting for materials and heat, and further improves the production line efficiency; The equipment management department strengthens the equipment spot inspection and maintenance management, improves equipment reliability, ensures stable production, and further optimizes the overhaul model and the accurate control of the overhaul process to reduce the energy waste before the overhaul and the resumption of production.
