【技术前沿】国内首台套1450mm高牌号硅钢冷连轧机组顺利投产

Core Viewpoint - The successful production of China's first domestically designed and manufactured 1450mm high-grade silicon steel cold-rolling mill marks a historic breakthrough in the core equipment field of high-end silicon steel cold rolling, breaking the long-standing monopoly of foreign suppliers [2][3]. Group 1: Technological Breakthrough - The 1450mm silicon steel cold-rolling mill is the first small-diameter six-stand cold-rolling mill designed and manufactured by China First Heavy Industries, overcoming critical technical challenges in the six-stand small-diameter cold rolling process [3]. - This achievement significantly enhances China's core competitiveness and technological influence in cold-rolling equipment, ensuring complete autonomy in high-end silicon steel cold-rolling equipment [3]. Group 2: Market Impact - The successful commissioning of the mill provides a solid guarantee for the localization of high-value-added products such as silicon steel, promoting the high-end and cluster development of China's metallurgical materials industry [3]. - The collaboration between China First Heavy Industries and Sanbao Group on this project represents a deepening partnership following their previous work on the 1780mm hot-rolling project, aiding Sanbao Group in upgrading its product structure and expanding into high-value product lines [5]. Group 3: Future Outlook - China First Heavy Industries aims to continue its mission of "Equipping China, Going Global," driving domestic cold-rolling equipment from a position of "catching up" to "leading," contributing to the intelligent and green high-quality development of China's steel industry [7].
