"Lean" power, "accounting" effective, the indicators to improve11.14

Hot rolling mill adhere to lean management, strengthen accounting operation, lean management thought through the whole process of production and operation, strengthen the "minimum energy, stable quality, centralized production" lean production concept, deep exploration of cost reduction and efficiency potential, achieved remarkable results. Since the beginning of this year, the rolling time of billets has been reduced by 7.16 seconds/branch, and the process energy consumption has reached the best level in history, laying a solid foundation for the completion of the annual task target.

In the wave of lean innovation, the factory has increased its efforts to promote lean thinking and tools into the front line to achieve fine management of production processes. "We take cracking process bottlenecks as the main direction of attack, advanced standards, strengthen the coordination of various processes, encourage scientific and technological innovation, and constantly break through traditional thinking patterns, break path dependence, crack weaknesses, and form top-down and bottom-up forces." Said Li He, regional division of the production technology room of the factory.

Through technological innovation and lean management

"Dual engine" to restrict the rolling rhythm of the increase

Rough rolling descaling speed, increase SP step size

Optimize the inspection conditions of flying shear entrance

Eight processes and chain conditions were improved

Solve 3 function problems such as stop waiting function after swinging steel

By sorting out the process flow, identifying energy factors, strengthening the fine management of energy, changing the extensive energy use management mode, limiting cost control, and leveraging the advantages of collaborative support, promoting the whole process of hot rolling from slab storage to steel coil storage, full process dynamic monitoring and intelligent analysis, establishing hourly, shift and daily production management mechanism, and reducing the billet heating time. The furnace time is shortened by 30min, the power consumption is reduced by 1.96kWh/t and the coal consumption is reduced by 0.03GJ/t compared with the average level of last year. In view of the current production practice, we have actively explored energy-saving production modes and developed a "one-key energy-saving" system to realize energy consumption prediction and pre-control and dynamic control.

Change the old ideas, establish the overall situation of the production line "one game" awareness, through the solid promotion of lean management concept, strive to know lean, dry lean, the new concept into the daily work, strive to eliminate all the links and waste that do not produce value, standardize the work process, improve work efficiency. Carry out the "thinking and enjoying" forum, move the "desk" to the site, find topics in combination with the actual production, especially in the field of technology, equipment management, etc., conduct a deep analysis of typical cases of the production line, establish a solution thinking, summary experience, achieve a deep integration of theory and practice, and improve the efficiency of solving on-site problems.

The plant will continue to promote lean management

Adhere to the organic combination of lean and production

Promote production speed and product quality

At the same time, we will implement all measures to reduce costs and increase efficiency

For the hot rolling mill to achieve the "30600" production and management target contribution
