近日，我国成功投产全国最大断面特厚板坯连铸机，标志着高端钢铁制造装备技术实现重大突破。该连铸机由中冶赛迪自主研发设计，最大铸坯断面尺寸达420mm×2600mm，是目前国内断面最大的特厚板坯连铸设备，可满足核电、海洋工程、重型机械等高端制造业对超厚钢板的迫切需求。该设备采用多项自主创新技术，包括动态轻压下、电磁搅拌、智能冷却控制等，显著提升了铸坯内部质量和尺寸精度，有效减少后续轧制工序的能耗与损耗。此次投产不仅填补了国内在超大断面连铸领域的技术空白，也增强了我国在高端特厚钢板领域的自主供应能力，对推动钢铁行业绿色低碳转型和产业链安全具有重要意义。
Recently, China successfully commissioned the nation’s largest cross-section heavy slab continuous caster, marking a significant breakthrough in high-end steelmaking equipment technology. Developed and designed independently by CISDI Engineering Co., Ltd., the caster features a maximum slab cross-section of 420mm × 2600mm, making it the largest heavy slab continuous caster currently operating in China. It is capable of meeting the urgent demand for ultra-thick steel plates in high-end sectors such as nuclear power, offshore engineering, and heavy machinery. The equipment incorporates multiple innovative technologies—including dynamic soft reduction, electromagnetic stirring, and intelligent cooling control—significantly improving internal slab quality and dimensional accuracy while reducing energy consumption and material loss in subsequent rolling processes. This commissioning not only fills a domestic technological gap in ultra-large cross-section continuous casting but also strengthens China’s self-reliance in supplying high-end heavy steel plates, playing a vital role in advancing the steel industry’s green, low-carbon transformation and ensuring supply chain security.
