| 小方坯菱形变形 | billet rhomboidity (Billet rhomboidity (or off-squareness) which is defined as the difference between the lengths of the two diagonals, has been a major quality problem since the inception of continuous billet casting. 自小方坯连铸诞生之初，其定义为两对角线长度之差的小方坯菱形变形 (billet rhomboidity 或 billet off-squareness) 就已成为主要的质量问题。) |
