When rolling the cylinder shell, since there is no pre-bending step, how is roundness achieved in the end?
It is determined based on a comprehensive assessment of factors such as the cylinder diameter and steel plate thickness; those with larger diameters or thinner plates may not require pre-bending, and can be formed through welding.
