In the world of steel production, even the smallest details can have significant impacts on the final product and overall efficiency. A recent study published in *Teshugang* (which translates to “Iron and Steel” in English) sheds light on one such detail: the effect of mold corner radius on the thermo-mechanical behavior of bloom shells during casting. The research, led by Li Jing, offers valuable insights that could reshape practices in the energy sector, particularly in steel manufacturing.
The study employed a coupled thermal-mechanical model using Marc software to simulate the dynamic heat exchange between the mold and the solidifying bloom shell. The focus was on analyzing how the radius of the mold corner influences temperature, stress, and strain distribution in the bloom’s local shell and the mold itself.
Li Jing and their team found that for blooms with a cross-section of 280 mm x 380 mm, the optimal mold corner radius lies between 17.5 and 20 mm. “When the radius is smaller than this range, the temperature gradient in the local zone near the bloom corner becomes larger,” Li Jing explained. “This is detrimental to the homogeneous development of the bloom shell.” Conversely, when the radius exceeds this range, the increased contact normal force between the mold and the bloom shell can lead to starlike cracks on the strand.
The implications of this research are substantial for the energy sector, particularly in steel production. By optimizing the mold corner radius, manufacturers can enhance the quality and consistency of their blooms, leading to more efficient and cost-effective production processes. “Understanding these nuances allows us to fine-tune our casting processes, ultimately improving the overall yield and reducing waste,” said a senior engineer at a leading steel manufacturing plant.
The study’s findings could also pave the way for advancements in mold design and material selection. As the energy sector continues to evolve, the demand for high-quality steel products remains steadfast. Research like Li Jing’s is crucial in meeting these demands while driving innovation in the field.
Published in *Teshugang*, this research serves as a testament to the importance of meticulous attention to detail in industrial processes. As the steel industry strives for greater efficiency and sustainability, insights from studies like these will be instrumental in shaping the future of manufacturing.
