Thin-strip casting—modelling of the combined casting/metal-forming process

Effect of Si Content on Strip Thickness and Solidified Structure in High-Speed Twin-Roll Cast Al-Si Alloy Strips

“…The fine dendrites in the mid-thickness region indicate that the residual melt in this region solidified at a very high cooling rate near the minimum roll gap, where good heat transfer can be achieved with the help of roll separating force keeping a good contact between the roll surfaces and the solidified shells. 18) In relatively high Si compositions over 5 mass%, large amount of Al-Si eutectic phase was observed in the central band region instead of globular grains and fine dendrite structure. These results suggest that thickness of band structure was not different so much depending on Si content, but the solidified structure of the band region varied evidently with Si content.…”

Thermal crown analysis of the roll in the strip casting process

“…Kopp et al (1997) reported that the "M" shape crown occurs when there is a void inside the casting rolls and the width is larger than the diameter. On the other hand, Kopp et al (1998) found that when the width of the casting rolls is small, a parabolic roll crown is formed instead of the "M" shape roll crown. The "M" shape crown illustrated in Fig.…”
