在先进制造链南京钢铁展区，有个会"讲故事"的钢铁空间。 在智慧大屏上，汇聚了26条生产线，一块来自非洲或者澳大利亚的小矿石，在这里逐渐成长为钢筋铁骨的全流程清晰可见。 大屏幕下边展示的是智慧连铸生产场景，很多重要材料都由它生产而来。沙特的海上油田、非洲首条电气化轻轨、克罗地亚佩列沙茨跨海大桥等，都有它的 身影。 在南钢的"朋友圈"里，全球400多个大国重器和超级工程中，都能找到这样"你中有我"的合作印记。把它们链接起来的特殊的钢铁是怎样炼成的？ 链博会的"链"，是全球伙伴手拉手的纽带。这条看不见的"链"，一头扎根中国的工厂车间、智慧港口，一头串联起世界经济齿轮的高效运转。数智化时代， 钢铁产业链也已经被重新定义，一块铁矿石的旅程不再只是滚烫的炉火与锻造，而是冷静的云端与算法。 南京钢铁集团数字应用研究院联席院长 徐发喜：通过大数据、人工智能和数字孪生等技术，实现钢铁管理远程化、集约化、智能化，重塑钢铁生产运营模 式。 7天后，这款耐磨钢将用在矿山工程机械的铲斗上，远销非洲、澳大利亚等地。根据全球需求实现数智化定制，北极的LNG项目中，企业生产的低温钢 在-162℃下依然坚韧；在3000米海底，抗大变形管线钢承 ...
