It matches the speed and transmits the torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.
The purpose of sizing is to roll the steel pipe into the required dimensional accuracy and roundness under the condition of small total reduction rate and small single diameter rate.
The process of steel pipe sizing, reducing and tension reducing is the continuous rolling process of hollow body without mandrel.
After sizing the steel pipe, the diameter deviation is small, the ellipticity is small, the straightness is good, and the surface is smooth.
