钢板在轧制过程中易产生带状组织，而带状组织的形成降低了钢板的横向冲击性能，为了了解带状组织的形成原因，在实验基础上研究了两种成分钢的控制轧制和加速冷却工艺。结果表明：在采用未再结晶区大变形的控制轧制工艺时，必须采用加速冷却工艺来减小或消除带状组织。另外，采用Ｎｂ，Ｔｉ微合金化也是消除带状组织的有效手段。
In the process of rolling, steel strip tends to produce banded structure, while the formation of banded structure reduces the transverse impact performance of steel sheet. In order to know the formation reason of banded structure, the control rolling and Accelerate the cooling process. The results show that the accelerated cooling process must be adopted to reduce or eliminate the banded structure in the control rolling process with large deformation of the non-recrystallized zone. In addition, the use of Nb, Ti microalloying is also an effective means to eliminate banding.
