摘要
挤压辊是高频焊管机组的重要工艺装备。目前生产口径大于114mm焊接钢管时均采用多辊式挤压辊,其支架结构复杂,调整困难,易引起焊缝质量波动。新设计的二辊式多层组合挤压辊结构独特,实际使用效果良好。
The extrusion roll assembly is a critical part of the hi -frequency welded pipe mill.Nowadays,hi -fre-quency welded pipes with O.D.above 114mm are produced by means of the conventional multi -roll extrusion asse mbly which has such disadvantages as rath er complicated frame,inconvenient adjustment and inconsistent qualit y of pipe weld seam.It has been proven that the subj ective extrusion roll assembly with a unique two -high /multi -level stru cture newly developed by the author's own company is very effective in operation.
