PQF、CPS和PAM轧管新工艺浅论

    Discussion on New Pipe Rolling Processes of PQF, CPS and PAM

    • 摘要: 介绍了自曼内斯曼兄弟发明斜轧穿孔工艺以来,连续轧管、三辊轧管、MPM轧管、行星轧管工艺相继发明并投入生产的简要情况。近些年,CPS轧管工艺在南非已进行试验;第1台PQF轧管机组已在中国天津投产;行星阿塞尔(PAM)的设想已有雏形。简述PQF、CPS和PAM这3项轧管新工艺的特点,分别对其“新”的程度进行了比较和评价。指出PAM工艺将有可能从设想变成现实,并预测未来钢管生产领域还会有重大发明。

       

      Abstract: Briefed in the paper is the history concerning inventions and operations of the seamless steel tube rolling processes,namely continuous rolling,three-roll rolling,MPM,and planetary mill,which were born Subsequent to the invention of the rotary piercing process by the Mannesmann brothers. Over the recent years,the CPS process has been experimented in South Africa;the first PQF mill has been put into operation in Tianjin,China,and the embryonic form of the planetary Assel mill(PAM) has been conceived. Also briefed are the respective features of the said three new pipe rolling processes,and a comparison of the advancement levels of the three processes as "new" techniques and evaluations thereof are made. The author forecasts a possibility of turning the PAM dream into reality some day in the future,and more sensational inventions to be made in the arena of steel tube industry.
