近两年来，河钢舞钢深入贯彻集团战略部署，坚定特钢道路，聚焦“市场”和“产品”两大主题，坚持用特钢的技术制造世界一流的产品，倾力锻造特钢精品、国之重器，在发展特钢产品、提升特钢技术上不断打造新的里程碑，焕发出勃勃生机。
8月6日9时，河钢舞钢四米三宽厚板精轧机升级改造项目现场，激情似火，鞭炮齐鸣。经过历时11个月的施工建设，河钢舞钢万名职工翘首期盼的四米三宽厚板精轧机升级改造项目建成投产，这标志着河钢舞钢在写好“特”字、做强特钢、打造“单打冠军”、勇做宽厚板领军企业的道路上又迈出了坚实的一大步。
至此，河钢舞钢拥有两条四米以上双机架宽厚板生产线。在一轧钢4200mm宽厚板产线，中国第一架4200mm粗轧机和新建的4300mm精轧机优势互补、有机匹配。4200mm轧机可以发挥其开口度大、轧制特厚板的优势；4300mm轧机轧制力大，轧制精度高。双机架匹配运行，有效解决原有4200mm轧机轧制力小、精度低等问题。在二轧钢4100mm宽厚板产线，4100mm粗轧机和4100mm精轧机相得益彰，轧制压力大、自动化程度高、控制精确的优势得以充分发挥。
两套四米以上双机架宽厚板轧机生产线让河钢舞钢在高端宽厚板研发上更有底气，进一步扩大了河钢舞钢在中国宽厚板行业的领跑地位。
世界首套300mm级特厚淬火机大显身手
2017年11月4日，河钢舞钢成功建成投用世界首套300mm级大断面特厚钢板辊式淬火机。目前，河钢舞钢立足世界首套300mm特厚钢板淬火机先后开发出了特厚板淬火、正火、回火和NAC四种全套功能，生产范围涵盖了S500Q、12Cr2Mo1VR等50多个钢种，厚度范围扩大至80～300mm，月产高端大厚度产品5000多吨。
2019年6月1日8时，河钢舞钢新线轧钢产线上，新建的一条回火热处理线正式投用。它的投用，可确保河钢舞钢高端钢板及时交付，同时在保证加热质量的前提下实现节能、环保目的，助力河钢舞钢产品结构调整优化和客户结构优化再上新台阶。
2019年8月5日，在河钢舞钢新线轧钢产线上，具有世界先进水平的预矫直机正在对一块刚轧制完的超厚钢板进行矫直。这是河钢舞钢为国内单机容量最大的抽水蓄能电站关键部位用钢所生产的超厚度高等级水电钢。
依托对预矫直机和超快冷系统的升级改造，河钢舞钢实现了DQ工艺的钢板在线淬火，不但在超厚钢板开发领域取得了新突破——成功生产包括屈服强度达420～500MPa的调质高强钢板在内的多个高端钢种，而且在对极限规格15毫米薄板的板形控制上也达到国内一流。
近两年来，河钢舞钢主动对接河钢集团各类技术研发平台，先后6次邀请河钢产业技术研究院来到河钢舞钢，对产线进行“起底式”诊断，展开了16个宽厚板产业升级改造项目。从炼铁系统到炼钢系统再到轧钢系统，河钢舞钢积极推行技术、设备升级改造，破解制约产品高端化的瓶颈问题。对高炉出渣转鼓实施改造，提高了出渣转鼓设备运行效率；对河钢舞钢二炼钢连铸机液压系统、二冷水系统等进行改造，提高了连铸机精度，显著提高了铸坯内部质量；对4100mm轧机高压水除鳞系统进行升级改造，对老线轧钢系统的翻板机进行改造、新上钢板标印机等。
自2017年开始，河钢舞钢全面提升自动化、信息化融合和智能制造发展进程，实施了河钢舞钢智能制造一期工程。主要完成了系统一体化的整体改造，在自动化、信息化、互联网和智能化四个层次上深入创新，广泛应用新的智能化技术等。
2019年6月5日，河钢舞钢新建高炉煤气加压机项目正式投用。高炉煤气加压站的建成投用，不但保证了高炉煤气管道压力稳定，还大大提高了钢坯加热速度及产品质量。
今年以来，河钢舞钢充分利用自身专业优势，大力发展现代工业服务业，努力实现特钢“增值”。其中，新上的河钢舞钢钢板深加工延伸产线，就是河钢舞钢和客户的无缝对接，打通直面客户的“最后一公里”的标志性项目。目前，河钢舞钢通过延伸产业链条，提供增值服务，已经与GE天津公司、安德里茨（中国）、徐工集团等众多国内外知名企业建立起稳定的合作关系。
8月28日，河钢舞钢改造一新的钢板深加工产线上，为国内某知名央企生产的重点桥梁项目主桥钢箱梁加工件正在有序加工中。这座大桥所需的3251吨、7121件钢箱梁等加工件全部产于河钢舞钢，最大加工件单重10吨，最小加工件单重100公斤。这是河钢舞钢首次实现“整桥用钢全部深加工供应”，对促进现代工业服务业发展工作有着里程碑的意义。
潮平两岸阔，风正一帆悬。
在河钢舞钢领导班子的坚强带领下，做特钢、打造独一无二产品、打造“单打冠军”、打造宽厚板领军企业的战鼓已经擂响，一个更具突出特色、更具明显优势、拥有更多“单打冠军”的新河钢舞钢正在茁壮成长，向着光明的未来阔步前进！
