width-to-thickness aspect ratio(A width-to-thickness aspect ratio of 2.5 to 1.0 could be taken as the division between flat and long products. 宽厚比 2. 5比 1.0 可以作为扁平材和长材的分界线。)
widest equiaxed crystal zone(Moreover, by the combination stirring of M + S, the widest equiaxed crystal zone can be obtained with the least negative segregation. 此夕卜，如果采用结晶器+二冷区复合式电磁搅拌，则可获得最宽的等轴晶区和最轻的负偏析。)
slab width(Figure 5 indicates that in addition to gas flow rate, machine throughput and slab width affect the flow pattern of steel in the mold. 如图 5 所示，除气体流量外，铸机过钢量和板坯宽度也对结晶器内钢水流动模式产生影响。)
