Abstract
As a new technology, the ultra-thin strip casting technology has inherent advantages in the production of non-oriented silicon steel, with excellent initial texture and a short process. The effects of different melt superheat (15 ℃, 45 ℃, 65 ℃) on the interfacial heat transfer behavior and wetting phenomena of 2.5 wt.% Si non-oriented Electrical Steel produced by the ultra-thin strip were studied. The empirical findings indicate a swift surge in interfacial heat flow upon initial interaction between molten steel and the copper matrix. The cooling contraction of the molten material prompts the formation of an air gap between the solidified billet shell and the copper substrate, resulting in a peak of interfacial heat flow followed by rapid attenuation. Elevating the superheat levels extends the solidification period, affording the molten material ample time to wet the substrate. This, in turn, fosters interfacial heat transfer and augments the interfacial heat flow.
