concave roll straightener 双曲线辊矫直机
Concave Work Roll 凹面工作辊
concave ground roll 中凹底辊
concave mould slot roll 凹型槽轧辊
The existing formula is focusing on the calculation in concave roll-shape design, which is very complex.
现有的辊形曲线计算公式以凹辊辊形的设计计算为主，且繁而复杂。
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。
