Aim to produce metal strips in millimeter scale, the Top Side-pouring Single Roll Casting process and the Top Side-pouring Twin Roll Casting process were investigated in this paper, using commercially pure lead and commercial-purity aluminum as the experimental materials. Numerical simulation was conducted before the experiment. The results show that, the Top Side-pouring Single Roll Casting process and the Top Side-pouring Twin Roll Casting process can both realize the uniform flow distribution and rapid solidification, but the surface of the strips cast by the former are irregularity because of free solidification, while that from the latter present a state of rolling. And one can change the gauge of nozzle and the speed of cooling roll, to regulate the thickness of thin strips, and by changing the shape of the nozzle, the thickness distribution can be handled.

Effect of secondary cooling on non-oriented electrical steel strips was investigated. The 2.0 mm thick cast strips contain two compositions were produced by twin-roll casting process, cooled in the air or cooled by spraying water. The microstructure was observed by optical microscopy, and EBSD was used to characterize the texture of the cast strips. The results showed that air-cooling cast strips have uniform and equiaxed grains with average size of 250 μm. The microstructure of the water-spraying cast strips compose of most equiaxed grains and a small number of abnormal big grains. At the same time, the secondary cooling rate mildly affects the cast texture strength but has no influence on the texture type.
