Optimization design on the roll array was done by taking two straight segments in the straightening machine.

采用了先进的具有两个连续矫直段的连铸机辊列曲线，对辊列进行优化设计。

There are also two roller straightening machine, relying on two rollers (Concave Intermediate, hyperbolic roll) the perspective of the different changes in the diameter of the material straightening.

也有两辊矫直机，依靠两辊(中间内凹，双曲线辊)的角度变化对不同直径的材料进行矫直。
