SMM Weekly Maintenance Report: Impact on Molten Iron Production from October 26th to November 1st

Recently, the cold-rolled automotive sheet production at Pangang Xichang Steel Vanadium Sheets & Plates Plant achieved a key breakthrough, with automotive sheet yield improving 0.26% YoY, and product quality reaching its best level since commissioning. Automotive sheets are the plant's flagship product for profit growth. As capacity has expanded significantly, the high-volume, high-throughput production conditions have posed greater challenges to end-to-end process, equipment, operations, and quality control. To address losses from inclusions, downgrades, and cutting scrap during production, the plant focused on the entire production chain—steelmaking, hot rolling, pickling and cold rolling, and continuous annealing—carrying out defect tracing, tiered control, and closed-loop rectification. At the same time, it refined special assessments on yield for each process step, continuously optimized core processes such as rolling, annealing, and shape control, strictly implemented end-to-end management from slab charging to finished product warehousing, and resolved production bottlenecks one by one. This indicator breakthrough is the result of coordinated efforts across production, technical, equipment, and quality positions. Frontline technical personnel continuously optimized process plans, operators strictly followed standardized operations, and quality personnel improved ledger management and closed-loop handling of quality issues, comprehensively and rigorously controlling product losses. Going forward, the plant will continue to consolidate the results of this campaign, tap deeper into indicator improvement potential, precisely rectify end-to-end production losses, and further optimize automotive sheet products to achieve dual improvements in capacity scale and product quality, burnish the Pangang automotive sheet brand, and help the enterprise improve quality and efficiency.

El 31 de agosto, Angang Guangzhou Automotive Steel y SMS celebraron una ceremonia de lanzamiento en línea del proyecto del Sistema de Ejecución de Calidad de Proceso Completo (QES). Los equipos de gestión del proyecto y ejecución técnica de ambas partes asistieron a la reunión, dando inicio oficialmente a la construcción del proyecto. Basado en las necesidades de gestión de calidad de productos de acero automotriz de alta gama, este proyecto colaborativo ayudará a Guangzhou Steel a completar una actualización iterativa integral de su sistema de gestión de calidad y a desarrollar capacidades de control de calidad digital más sólidas, marcando un hito importante en el impulso de la empresa hacia la fabricación inteligente y la transformación digital acelerada. La solución de calidad QES proporcionada por SMS a Guangzhou Steel está estrechamente adaptada a los requisitos comerciales personalizados de Guangzhou Steel, abordando los objetivos de desarrollo duales de la empresa: flexibilidad de proceso en la capacidad y calidad del producto consistentemente estable, y construyendo un sistema de aseguramiento de calidad de circuito cerrado de cadena completa que cubre la recopilación de datos, el análisis, la evaluación y la toma de decisiones de gestión.
