| Abstract: |
Sponge iron, also called Direct Reduced Iron (DRI), is produced by reducing iron oxide below its melting point and has become an important feedstock for electric arc and induction furnace steelmaking, particularly in regions without access to large-scale coking coal reserves [1], [2]. The engineering of a DRI plant involves two distinct but interconnected design disciplines: process and layout drafting, typically performed using AutoCAD, and structural analysis and design of supporting steel and concrete members, typically performed using STAAD-Pro [3], [4]. This paper presents a meta-analytical review of existing literature on the application of these two software tools to industrial plant design, with specific emphasis on sponge iron plants. The methodology section outlines a structured approach for comparing published case studies on STAAD-Pro based structural design and AutoCAD based plant layout, the load combinations and design codes typically referenced, and the integration points between drafting and analysis workflows. A critical analysis identifies recurring gaps in the literature, including limited documentation of kiln-support and conveyor-gallery design, insufficient treatment of thermal and dynamic loading unique to rotary-kiln based DRI plants, and a general scarcity of dedicated DRI-plant case studies compared to the abundance of generic building and bridge studies. The discussion synthesises these findings into a proposed integrated design workflow, and the conclusion highlights directions for future research, including parametric BIM-linked structural optimisation for sponge iron plants. |
