In order to fully implement the fourth quarter production tasks issued by Hebei Xinda Iron and Steel Group Co., LTD., the ironmaking plant is driven by time and trend, focusing on the core of "lean control", strengthening production process control and innovative cost management mode. Recently, the ironmaking plant has set up a working group headed by Peng Dingchang to develop and improve the guarantee measures for stable production and consumption reduction, and clarify the production targets, fuel ratios and coal ratios of blast furnaces. At present, the whole factory is in a decisive attitude to seize the gold season of iron and steel smelting, relying on lean management, and striving for benefit growth points.

Lock the target, work together to solve problems and increase efficiency

According to the company's deployment, at the beginning of October, the ironmaking plant organized the production organization and index improvement and cost reduction meeting to jointly solve the urgent problems of the whole plant. Group supply company, human resources planning Department, production department, technology department, Finance department, equipment department, quality measurement department, information automation Department, engineering department, energy and power plant and other department leaders attended the meeting, the blast furnace workshop of the ironmaking plant and various auxiliary sections of the person in charge attended the meeting.

At the meeting, Zheng Yuping of the ironmaking plant reported the guarantee measures for stable production and consumption reduction throughout the month, and units such as blast furnace workshops and equipment departments reported work on problems affecting production. In response to the typical questions raised at the meeting, the company responded to the departments one by one, and put forward guiding opinions on the specific work such as the production organization of the iron making link, energy conservation and consumption reduction.

For the next step, the ironmaking plant combined with the spirit of the meeting, refining and improving the solution task decomposition, and tasked the blast furnace workshop, production technology department and other units to refine their responsibilities, eyes to practice internal work, by building confidence, excellence, solid work in technology and peripheral protection, improve production efficiency.

Practice internal skills, lean control and do not relax

In order to restrict the bottleneck of production, the ironmaking plant has clarified specific indicators in terms of coke supply, coal injection, sinter, pellets, lump ore, oxygen enrichment, equipment spare parts support, and comprehensive furnace grade, and focused on refining specific measures to stabilize internal production. First, the blast furnace system is required to train the internal work, must maintain the air oxygen operation, and set targets for the silicon content of hot metal, average air temperature, coal ratio, load in the process of weighing, iron before the furnace, hot metal transportation, and other aspects of the furnace and water system maintenance index decomposition; The second is to charge the auxiliary section with reasonable planning, control the amount of the upper silo, and do a good job in the transfer of iron ladle for hot metal transportation, and further focus on key work such as energy saving and electricity consumption.
In terms of energy control, Zheng Yuping of the ironmaking plant requires the coal injection section to further refine measures, and save production electricity consumption by grasping the peak-avoidance management of large equipment such as coal injection mills. At the same time, the BF workshop combined with the operation section to refine the BF BPRT operation guarantee measures. Since the top pressure of the blast furnace needs to be stably adjusted after the turbine is put into operation to prevent the turbine from automatically breaking off, the top pressure of the turbine into and out of operation section is adjusted, and 60KPa is reduced on the original basis to shorten the turbine withdrawal time and improve the unit's working efficiency. In order to shorten the unit exit time, the BPRT control room starts to warm up the unit when the top pressure of the blast furnace reaches a certain state after the blast furnace reblast. In addition, when the blast furnace condition is adjusted, the top pressure does not reach the BPRT unit self-retreat critical point, no longer manual retreat, reduce the unit due to furnace condition problems frequent retreat and input, each time can extend the turbine input time of 20 minutes, saving the company's electricity cost.

Sincerity smooth the way to success. Based on the new starting point in the fourth quarter of 2024, Hebei Xinda Iron and Steel Group Co., Ltd. will adhere to self-reliance, identify the main direction of attack, focus on lean management and control, go all out to tackle key indicators, and ensure that the production organization process should be efficient to achieve new results in cost research. Conform to the development of The Times, form a strong closed loop of continuous improvement, self-renewal and spiraling, improve the core competitiveness of enterprises and market share, so that Xinda's "fist" is harder, more advantageous, higher efficiency and better efficiency, and win the final battle throughout the year!
