When market competition becomes extremely fierce and customers' demands for product quality become increasingly strict, the industrial solid waste resource utilization plant of Hebei Xinda Steel Group Co., Ltd. has faced multiple challenges and broken through the deadlock with an active and innovative attitude. Adhering to the consensus of all staff that "zero error in detail control and no end to quality improvement", taking quality breakthroughs as the core handle, we accurately solve the pain points and difficulties in production, steadily move forward on the road of quality improvement and cost reduction, and inject strong impetus into the high-quality development of the group.

Targeted efforts

Form a breakthrough team to identify the core problem

In response to the gap between its products and the advanced level of the industry, the industrial solid waste resource treatment plant promptly took action, drawing on key personnel from equipment, maintenance, and production fields to form a "Quality Improvement Breakthrough Team". Relying on the QC brainstorming mechanism, the team poolated their wisdom and conducted a thorough inspection of the entire production process, identifying over ten potential influencing factors. After meticulous analysis and precise screening of each item, they ultimately identified three core issues: fluctuations in the quality of raw water slag, unstable quality during the start-up and shutdown stages, and fluctuations in specific surface area. This laid a solid foundation for subsequent precise policy implementation and targeted breakthroughs.

Precise policy implementation

Three major measures are implemented in parallel to build a solid quality defense line

Source control stabilizes raw materials and consolidates the production foundation

In response to the problem of large fluctuations in the quality coefficient of raw material water slag, the task force established a deep coordination mechanism with the ironmaking plant, set up a dynamic adjustment mechanism for raw material ratios, and carried out water slag quality testing in advance to control the quality of raw materials from the source. The Equipment Department has simultaneously strengthened the management of spare parts declaration and arrival, strictly implemented the point inspection and maintenance system for the slag conveying system, promptly eliminated potential equipment defects, and prevented unplanned shutdowns. At the same time, it has optimized the raw material transfer process, reduced the frequency of vehicle transportation, and avoided disorderly material consumption, comprehensively stabilizing the quality of water and slag.

Optimize processes to avoid shocks and ensure stable production

Facing the quality control challenges caused by frequent start-ups and shutdowns under the policy of avoiding peak and off-peak periods, the task force took the initiative to collaborate with the production and operation departments as well as the sales department. They skillfully utilized the peak inventory periods to carry out equipment defect elimination in a concentrated manner, further optimizing the start-up and shutdown operation procedures. Through scientific planning and process upgrading, the period of unstable product quality has been shortened by nearly half, minimizing the impact of peak avoidance production on product quality to the greatest extent.

Fine control enhances accuracy and stabilizes product indicators

To address the issue of fluctuations in specific surface area, the team strictly implements the "first in, first out" principle for raw materials, giving priority to raw materials with good grindability to ensure the stable operation of the mill. Through repeated experiments to optimize process parameters, standardized operating procedures are formulated. At the same time, monthly evaluations of quality control indicators in the central control room are conducted to fully stimulate employees' sense of responsibility and operational accuracy, promoting the continuous stability of product indicators.

The breakthrough has achieved results.

The quality has steadily improved, breaking through market challenges

Through the unremitting efforts of all members, the product quality of the industrial solid waste resource utilization plant has achieved a qualitative leap, with the activity level remaining stable at over 95% within 7 days. The core indicators have steadily improved, and it has successfully entered the ranks of high-quality products. High-quality products not only provide a solid support for higher market pricing, effectively increasing the profit margin per unit, but also win the wide trust of customers.

Conclusion

High-quality products lay a solid foundation to break through the deadlock, and cost reduction and efficiency improvement write a new chapter. The industrial solid waste resource treatment plant of Hebei Xinda Steel Group Co., Ltd. has broken through development bottlenecks by targeted breakthroughs and consolidated the quality foundation through meticulous control, delivering an outstanding performance on the journey of improving quality and reducing costs. In the future, the industrial solid waste resource treatment plant will continue to uphold the spirit of craftsmanship that pursues excellence, delve deeply into technological innovation, and optimize management efficiency. With better quality and higher efficiency, it will empower the high-quality development of the group, maintain a leading position in market competition, and strike a strong note of green circulation and efficiency leap in The Times!
