There are some problems,such as difficulties in data fusion,imbalanced process development,low accuracy of key process control models and insufficient collaboration and sharing between internal and external enterprises,in the manufacturing process of Shandong Iron and Steel Group Co.,Ltd.To address the above problems,a multi-source data collection and heteroge-neous data processing platform was built in Shangang,and the automatic conversion,matching and spatiotemporal synchroniza-tion of heterogeneous data were carried out.A dynamic digital twin model using data-driven fusion mechanism was applied to ad-dress key control challenges in processes of smelting and hot rolling.Through the digital industrial chain/supply chain collabora-tion platform for the steel manufacturing process,future-oriented digital innovation applications and steel digital collaborative manufacturing have been achieved.After the application of relevant technologies,the accuracy of order delivery has reached over 96.56％,and the per capita steel production has reached over 1 710 tons.
