Lean management is like a meticulous practice, the carving of each link, the accumulation of each improvement, are gathering great power for the development of enterprises. In the fierce competition in the iron and steel industry, the steel production line of the steel rolling plant relies on the "sharp edge" of lean management to accurately break the game, achieve the all-round upgrading of production and management, and walk out of a high-quality development of innovation.

Field lean

Create an orderly production "stage"

Stepping into the production site of the steel production line of the steel rolling plant, it seems that you have entered a well-laid and efficient "stage". The goods are arranged orderly, the equipment is shiny as new, all kinds of signs are eye-catching and clear, and every detail demonstrates the charm of lean management.

The identification and radical treatment of "six sources on site" are in full swing. Through careful investigation, difficult sources of cleaning, pollution sources, waste sources, etc., will be singled out and broken. In the past, the distribution box accumulated serious dust, which not only affected the heat dissipation of the equipment, but also had security risks; The oil spill of finishing mill motor is not only a waste of resources but also not beautiful. Now, after special rectification, the distribution box has a new look, the motor has bid farewell to the oil pollution, and the equipment is more stable and reliable.

The management of on-site movable items is a highlight. With the advancement of spare parts transfer and other work, the number of movable items has increased, but the fixed rate has steadily increased. The principle of "there must be a place, there must be a classification, classification must be marked, and identification must be standardized" is deeply rooted in the hearts of the people, and employees are more convenient and efficient in accessing items, greatly saving time and significantly improving production efficiency.

In order to make the site environment more clean and beautiful, the steel production line of the steel rolling plant has also carefully created a number of highlight areas. The bottom column base and column of the finished product warehouse are newly painted, and the color is bright. The lawn is neatly mowed and green; The roller frame of the production preparation workshop is repainted, the self-leveling kanning board is wiped and maintained regularly, and the entire factory area is full of vitality and has become a bright business card for the external display of the image of the enterprise.

Equipment lean

Build a solid "backing" for production

Equipment is the core "weapon" of production, the steel production line of the steel rolling plant knows the importance of lean management of equipment, and takes full care of the equipment to ensure its stable operation.

The problem of cooling the water temperature of the cooling tower is a "contest" with the equipment. Faced with the problem of too high water temperature at the exit of the cooling tower, the technical team used the fishbone diagram to deeply analyze the reasons, and the key factors such as the poor effect of the accurately locked pipeline filtration system, the missing damage of the cooling tower packing, and the serious silting of the turbidity ring pool. Subsequently, the targeted transformation measures were developed, such as installing filtration devices, replacing fillers and supports, and cleaning up the silt of turbidity ring pool. After some efforts, the water temperature of the cooling tower is effectively controlled, which provides a strong guarantee for the stable operation of the equipment.

The equipment bathing activity lets the equipment "wash away the lead" and re-shine. In the activity, employees carefully wipe every corner of the equipment, remove oil and dust, and let the equipment reveal the original luster. This not only improves the appearance of the equipment, but more importantly, during the wiping process, employees can find potential problems with the equipment in time to nip the hidden dangers in the bud.

The online monitoring system is like the "intelligent brain" of the device, always paying attention to the running state of the device. By collecting and analyzing the data in real time, the system can find the abnormal situation of the equipment in time and send an early warning signal. Maintenance personnel can respond quickly according to this information and carry out accurate maintenance, effectively reducing the downtime of equipment failure and ensuring the continuity of production.

In addition, the establishment of equipment operation performance indicators has clarified the objectives and directions of equipment management. From the downtime of equipment failure to the daily spot inspection rate, to the completion rate of fixed repair projects, each indicator is responsible to the person to ensure that the equipment management work is implemented. The standard construction of the point inspection station, the independent maintenance and lubrication management of the equipment, and the rich and diverse single-point training have further improved the professional quality and skill level of the equipment management team, and laid a solid foundation for the stable operation of the equipment.

Process lean

Optimize the "key code" for production

Process lean is the "key code" to improve the production efficiency and reduce the cost of the section steel production line of the general steel rolling plant. Lean production line creation meeting and equipment meeting become an important platform for communication and coordination, at the meeting, all departments speak freely and jointly solve the problems encountered in the production process. From site environment improvement to equipment maintenance arrangements, from energy control to employee safety training, every decision is closely around the production reality to ensure the orderly progress of all work.

The next process satisfaction survey is an important standard to test whether the production process is optimized. The section steel production line of the General Steel rolling plant attaches great importance to customer feedback, and takes quick measures to solve the problems raised by customers. When the customer reflects the problems of packing tape, label falling off, etc., the factory immediately optimized the relevant operation process, lengthened the welding length of the packing tape, strictly standardized labeling requirements, and won customer satisfaction and trust with practical actions, and improved the market competitiveness of the enterprise.

Team lean

The "powerful force" that unites the team

Lean team is the "cell" of enterprise development, and the steel production line of steel rolling plant vigorously strengthens the construction of lean team and activates the vitality of every "cell". The revision and training of standardized operation instructions for key positions have been steadily promoted, and employees have rules to follow in their work by continuously optimizing operation processes and standardizing operation standards. Monthly training for three shift personnel in each section, requiring all staff to recite the content of the operation guide, and 100% sample test to ensure that every employee can master the operation skills, providing a strong guarantee for product quality.

Independent improvement and special improvement activities stimulate the innovation enthusiasm of employees. From the transformation of the water pipe of the vertical roller box to the production of the chain arm spare parts frame, from the installation of the door of the monitoring camera control cabinet of the heating furnace operating table to the steel roller table under the cold bed, the improvement measures have condensed the wisdom and sweat of the staff. These improvements not only solve practical problems in production, but also reduce costs, improve efficiency, and more importantly, foster the sense of innovation and teamwork of employees.

"There is a long way to go, I will search up and down." Lean management is endless, and the steel production line of the steel mill has taken a solid step on the road of lean management, and has achieved remarkable results. But in the future, there are more challenges waiting for them to overcome, more goals waiting for them to achieve. It is believed that with the joint efforts of all employees, the steel production line of the steel rolling plant will continue to deepen lean management, constantly explore innovation, and move towards a new journey of high-quality development with a more determined pace, and write a more brilliant chapter!
