Abstract: 1070 aluminum thin slabs have been prepared using a novel vertical bending continuous casting(VC) technique, and the microstructure and properties of the hot-rolled 1070 aluminum slabs at a casting speed of 1.2 m/min have been investigated. The results show that the equivalent grain diameters at the surface and center of the 15 mm thick hot-rolled plate produced by VC casting are 600 μm and 578 μm, respectively, with aspect ratios of 6.8 and 6.6. The yield strength, ultimate tensile strength, elongation, and strength-elongation product of the hot-rolled plate are 52 MPa, 80 MPa, 46.8%, and 3 744 MPa·%, respectively. Compared with the 7 mm thick hot-rolled plate fabricated by twin-belt continuous casting(Hazelett) under a similar reduction ratio, the 15 mm plate produced by VC casting exhibits a higher dislocation storage capacity during tensile deformation, leading to a significantly enhanced work-hardening capability and a delayed onset of plastic instability. Consequently, the elongation increases by nearly twofold, and the strength-elongation product increases by approximately onefold.
