The self-lean concept has taken root in Hebei Xinda Iron and Steel Group Co., LTD., and all units have responded positively by running lean ideas through every link of production and operation. Taking site management as the starting point, they have made continuous efforts in equipment maintenance, process optimization, team construction and other aspects, and achieved a series of remarkable results, injecting strong impetus into the company's high-quality development.
In the development of Hebei Xinda Group, as an important part of the oxygen plant, lean management has always been the core driving force, constantly optimize the production process, improve the field management level, strengthen the equipment support ability, and achieve remarkable results in safety, quality, efficiency and other aspects, laying a solid foundation for the stable development of the group.
Lean site management
Create a clean and orderly new look
Stepping into the production area of the oxygen plant, you can feel the significant changes brought about by lean site management. All along, the oxygen plant has carried out in-depth "six sources" management work, and conducted comprehensive investigations on six categories of problems such as fault sources, pollution sources and dangerous sources; The equipment department works closely with the Safety Department to deal with the equipment oil pollution, oil leakage points and other problems in time to nip the hidden dangers in the bud; At the same time, strictly control the safety of single-machine maintenance operations, from the completion of the job ticket to the implementation of on-site safety measures, every link is strictly standardized to ensure the safety of the operation.
In terms of product placement management, the current placement rate of the oxygen plant is as high as 99.8%. Fire extinguishers, air breathing apparatus and other equipment are placed neatly and clearly, which not only improves the cleanliness of the scene, but also greatly improves the emergency response speed. The visual management is also fruitful, and the existing 127 visual signs are distributed in all corners of the plant, playing an important role. After the fractionating tower cold box, ball tank and other equipment are repainted anti-corrosion, not only the appearance is new, but also the service life of the equipment is extended; The roads in the factory are clean and tidy, the green plants are trimmed neatly, and the flowers bloom in all seasons, creating a comfortable and pleasant working environment for employees.
In addition, the oxygen plant built more than 20 functional station rooms, from the power distribution room to the main control room, from the water pump room to the shift room, the pass rate reached 100%. The indoor layout of each station is reasonable, the equipment is placed in order, and the operation is safe and stable, which provides a strong guarantee for the smooth progress of production. Employees actively participate in the improvement of points activities, through daily cleaning, green plant maintenance and help to other workshops, forming a good atmosphere for all employees to participate in and jointly improve. The maintenance section succession room, high-voltage distribution room and other areas are made into bright areas, which are not only clean and well-equipped, but also set up perfect risk notification plates and standard operating procedures, becoming an example for other areas to learn.
Lean plant management
Solid and stable operation of the hard foundation
Equipment is the core of production, oxygen plant attaches great importance to lean management of equipment. First of all, the key equipment and controlled points were comprehensively sorted out and updated in time, and a perfect summary table of equipment status controlled points was established, covering many categories such as electrical and mechanical, providing data support for accurate control of equipment.
The construction of the demonstration area led by TPM has achieved remarkable results, and the air compressor area has become a benchmark for equipment management. In terms of equipment cleaning, bathing, self-maintenance and lubrication management, the oxygen plant has also formulated detailed plans and strictly implemented, and a number of equipment have received comprehensive cleaning and maintenance, and the surface of the equipment is bright as new, the internal components are well lubricated, and the operation is more stable and reliable.
As a key link of equipment management, the inspection station has long maintained standardized operation and carried out various training from time to time. The professional skills of the inspection personnel have been improved, the equipment management standards have been more perfect, the hidden dangers of the equipment can be discovered and dealt with in time, and the equipment operation performance indicators have been established to ensure that the equipment operation is in line with industry standards.
Lean process management
Stimulate new vitality of synergy and high efficiency
Lean process management runs through the whole process of production and operation of the oxygen General plant. The Oxygen General Plant continuously optimizes the production process and strengthens the cooperation among various departments by holding regular meetings of lean production line establishment and equipment meetings. Lean production line creation meeting and equipment meeting are held regularly. At the lean production line creation meeting, all departments report night equipment operation, production completion and problem feedback in detail, discuss key issues of leadership and formulate solutions. Maintenance section, electrical instrument section, safety section, equipment section, inspection station, production section and other departments clearly work arrangements, responsibility to people.
"The accumulation of soil makes a mountain, and the accumulation of water makes a sea." Every exploration and practice of the oxygen plant on the road of lean management is a solid step and a trickle in the development journey of the group. For Hebei Xinda Group, each branch is like a closely aligned gear, which drives the group steadily forward. We must continue to be lean oriented, constantly tap our own potential, continuous improvement and innovation, contribute more to the high-quality development of Xinda with more efficient production mode, better quality products and services, and set up a model of lean management in the industry!
