Recent Status of Production, Administration Policies, and Low-Carbon Technology Development of China’s Steel Industry

“…On 18 November 2021, Baowu Steel Group established a Low-Carbon Metallurgy Innovation Center and completed the construction of a Hydrogen-enriched Carbonic oxide Recycling Oxygenate Furnace (HyCROF), providing support for the progress of low-carbon metallurgical technology [8]. In December 2022, through the implementation of the "Hegang Low-Carbon Product Plan", Hegang Group promotes the innovation of low-carbon technologies with upstream and downstream industries by using carbon reduction technologies such as biomass energy substitution and carbon capture utilization and storage (CCUS) [9]. In 2021, Capital Engineering & Research Incorporated was approved to establish the Low-Carbon Technology Research Institute (Beijing) of China Metallurgical Corporation, which provides a solid foundation for future low-carbon technology research and development.…”

Numerical Investigation on Solidification Shrinkage Behavior of P900 Hollow Ingot during Electroslag Remelting Process

“…In general, for traditional ESR process, multi-physical fields have been investigated by numerical simulation models, which are coupled with effective interfacial heat transfer coefficient or interfacial gap width between mould and ingot. [9][10][11][12][13][14][15][16][17][18] Therefore, to obtain optimize the H cyl and the DOI: 10.1002/srin.202100695 A numerical model coupled with a multiphysical field based on a simple density-based shrinkage model is established. After validation by comparing the experimental and simulation results, it is utilized to clarify solidification shrinkage behavior of electroslag remelting hollow ingot (ESR-HI) process and investigate the effect of the inner mould taper angle and ingot withdrawing rate on air gap width and interfacial heat transfer coefficient (HTC).…”

“…In general, for traditional ESR process, multi‐physical fields have been investigated by numerical simulation models, which are coupled with effective interfacial heat transfer coefficient or interfacial gap width between mould and ingot. [ 9–18 ] Therefore, to obtain optimize the H cyl and the inner mould taper angle ( θ ) and ingot withdrawing rate, it is seriously essential to develop a numerical simulation model of ESR‐HI, which can be utilized to investigate solidification shrinkage behavior.…”
