Description
Technical process of the welded pipe mill line: uncoiler, leveler,
shear and welder, accumulator, forming, HF welding, squeezing,
deburring, iron roll, air cooling, water cooling, sizing, flying
saw, straighter, end facing, packing
Working principle of accumulator: Hydraulic cylinder of strip
feeding unit holds down steel strip
Feeding motor drives the feeding roll to fill strip into the
accumulator by friction force
Main motor rotates supply roll of the accumulator cage in order to
store steel strip in the inner and outer storage zone in the
opposite direction
Drive motor will stop after one coil finished, and will resume
feeding after cutting and welding by another coil
Fixed rim accumulator: strip lead in from outer rim and discharge
from center
