PQF连轧管机在天津钢管的发展

Development of PQF Pipe Mill in TPCO

PQF连轧管机是目前工艺技术最为先进的限动芯棒连轧管机。简述了PQF连轧管机由轴向换辊(ACO)到侧向换辊(LCO)的发展历程。介绍了天津钢管集团股份有限公司已建成投产的3套PQF连轧管机组的主要设备、生产的产品品种规格等以及各自的特点。这3套PQF三辊连轧管机组的建设对推动行业装备与技术进步起到了积极的推动作用。

The PQF（Premium Quality Finishing）pipe mill has been so far regarded as the most technologically advanced retained-mandrel pipe mil1.And up to now,three sets of such mills have been set up,and put in operation at Tianjin Pipe（Group）Corporation Co.,Ltd.Briefed in the paper is the development of the roll change-over process of the PQF mill form the original axial change-over（ACO）method to the present lateral change-over（LCO）method.The three TPCO PQF mill lines are also described,covering such aspects as major equipment units,product mix,as well as the features of each mill.The establishment of the three TPCO PQF mills has played a positive role in speeding up further development of both equipment and technological level of domestic tube-making industry.
