服役32年浇铸5200万吨，攀钢钒“功勋铸机”升级8月31日，钢水按序流入中间包，随后缓缓注入结晶器，经扇形段冷却与矫直，最终形成形状规范的连铸坯。这一完整过程，标志着历经4个月22天改造的攀钢钒1号板坯连铸系统升级改造项目，成功实现热负荷试车。

攀钢钒1号板坯连铸机具有重大意义，它是中国第一条自主设计、制造成套的百万吨级连铸生产线，1993年10月18日建成投产。在长达32年的服役期间，该铸机累计浇铸铸坯5200余万吨。

随着时间推移，设备老化、技术迭代等问题逐渐显现。为提升生产效率与产品质量，攀钢钒启动1号板坯连铸系统升级改造项目。此次改造涉及多个关键环节，从结晶器的优化设计，到扇形段冷...
