Abstract
Steel is continuously cast in a mold at a casting speed of 2.5 to 10 m/min while the mold is oscillated so as to satisfy the relationship 450≦(S×f/Vc)≦1000, wherein S is the stroke of mold oscillation in mm, f is the frequency of mold oscillation in cycles per minute, and Vc is the casting speed in m/min.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A continuous casting method comprising continuously casting steel in a mold at a casting speed of at least 2.5 m/min and at most 10 m/min to form a slab while oscillating the mold so as to satisfy the relationship
450≦( S×f/Vc )≦1000
wherein S is the stroke of mold oscillation in mm (4 mm≦S≦15 mm), f is the frequency of mold oscillation in cycles per minute, and Vc is the casting speed in m/min.
2 . A method as claimed in claim 1 wherein the mold has a cavity with a thickness of 50-120 mm.
3 . A method as claimed in claim 1 wherein the mold has a cavity with a thickness of 70-110 mm.
4 . A method as claimed in claim 1 including hot rolling the slab after casting to form thin steel sheet without allowing the slab to cool to below its Ac 3 point between casting and hot rolling.
5 . A method as claimed in claim 4 wherein the casting speed Vc is less than 8.0 m/min.
6 . A method as claimed in claim 1 wherein the following relationship is satisfied.
