Lean management aims to achieve "less and better", and the concept of lean production line originates from lean production. After continuous development, lean management gradually extends from the initial production system management practice to the business management of enterprises, and produces the best quality products at the lowest cost with the production mode of refinement, punctuality, less humanization and automation to maximize benefits.

Hebei Xinda Iron and Steel Group Co., Ltd. raw material factory firmly implement lean management, improve quality and efficiency work deployment, closely around the "whole process, all employees, joint participation" management requirements, to "pressure responsibility, reduce costs, improve quality and efficiency" as the starting point, timely find gaps, make up for weaknesses, strong and weak items, continue to optimize the production workshop indicators, promote lean management work to make great progress, The management level and development capacity of enterprises have been steadily improved.

Take small steps, lean awareness and gather strength

Lean management is not a matter of overnight, but runs through every corner of production work. The raw material factory regulates the welding rod and bolt collar system in the secondary library, and informs the staff to support the welding rod according to the actual workload on the site, ensuring that the remaining electrode is about 30mm, which can avoid burning the electrode while saving the amount of welding rod and increase the service cycle of the electrode. Replace the bolts at the point of the equipment, and do not use gas cutting if the wrench is loosened, which can also increase the secondary reuse of bolts while saving the air source. The welding protective mask is not thrown down at will to ensure that the water is not handled lightly, and the service life of the welding protective mask is improved while the replacement frequency of the welding lens is reduced. The welding wire used in the field should not be confused with the gas welding hose, so as to avoid the damage of the gas welding hose caused by overheating and igniting the wire. The anti-tipping device should be installed with oxygen and acetylene gas cylinders to avoid the damage of the pressure gauge caused by the tipping of the gas cylinder.

Step steadily, quality management improve efficiency

Lean management is a systematic approach, quality is produced rather than tested, raw material plant by the process quality management to ensure the final quality. In the production process, quality inspection and control are carried out in each process to ensure that quality problems are found in time, and timely solutions are found to ensure stable production operation. Strictly implement the daily inspection system, timely deal with problems in place, and plan maintenance with high quality.
Adjust the ratio in time and reasonably according to the material inventory to ensure the permeability of the material layer. Sintering strictly implement the standard of coke powder, particle size and composition meet the requirements, regularly maintain the belt scale, avoid causing weighing errors, control the shaft furnace green ball particle size, green ball quantity strength. Feedback the current ball drop strength and particle size every 1 hour to improve the quality and ensure the supply of high quality raw materials in blast furnace.

Without stopping, equipment management increases efficiency

The raw material factory strengthens strict and lean management one by one process and one by one position, twists the "wet towel" of energy consumption and then twists it again, arranges personnel to dismantle and inspect the equipment that is replaced offline in time, and checks the internal wear situation. In line with the principle of compulsory repair and compulsory repair, the maintenance and utilization value are repaired, and the relevant equipment management personnel are scrapped if they cannot be repaired. Strengthen the promotion and implementation of the contents of the repair of old benefits and waste, set the goal and task of the repair of old benefits and waste for each production line team, and vigorously create a strong atmosphere of full participation in the repair of old benefits and waste. At the same time, the management of on-site spare parts is strengthened, the large spare parts are covered, the drum diameters of the transmission system are coated with oil, the maintenance costs and equipment costs are reduced, the overall lean management is implemented, and the production material and energy consumption are reduced.

The snow is light and the journey is thousands of miles. Hebei Xinda Iron and Steel Group Co., Ltd. will firmly tackle the difficulties, carry out the confidence and determination to catch up, grasp the time a little more tightly, do the work a little more detailed, further refine the equipment and equipment technical reform, production organization reform, process indicators fine control, technology research and development progress, management system improvement, so that lean management goes deep into every production link. Speed up structural adjustment, promote transformation, strengthen weaknesses, increase varieties, create benefits, take the lean road, innovation road, transformation road, stride green high-quality development of the grand road!
