    前擺式螺旋縫焊管機(jī)組帶鋼遞送跑偏問題的研究

    Research on Mechanism of Running Deviation of Steel Stripe as Being Delivered during Process of Front-swing HSAW Pipe Mill Line

    • 摘要: 分析前擺式螺旋縫埋弧焊管機(jī)組帶鋼遞送跑偏的機(jī)理；針對(duì)引起帶鋼遞送跑偏的諸多因素，提出改進(jìn)措施；并對(duì)出現(xiàn)的帶鋼經(jīng)遞送后向上遞送輥驅(qū)動(dòng)側(cè)跑偏進(jìn)行糾正。分析認(rèn)為：前擺式螺旋縫埋弧焊管機(jī)組帶鋼遞送跑偏的根本原因是由于帶鋼與遞送輥接觸部分的彈性變形量不同。通過選擇合理的遞送機(jī)壓力，準(zhǔn)確設(shè)定立輥位置，在遞送機(jī)前增加導(dǎo)板裝置，可抑制和糾正帶鋼跑偏現(xiàn)象。在糾正遞送跑偏問題時(shí)，還應(yīng)該綜合考慮跑偏原因，采取多方面合理措施才能有效地控制帶鋼的跑偏現(xiàn)象。

       

      Abstract: Analyzed in the paper is the mechanism of running deviation of the steel strip as being delivered during the process of the front-swing HSAW pipe mill.According to number of factors as causing the said running deviation of the steel stripe,improvement actions are proposed.Accordingly,the problem of steel strip deviating upward the drive side of the upper delivery roll is corrected.Based on the analysis,it is identified that the root cause for the said deviation is the difference between the elastic deformation amount of the steel strip and that of the contacting section of the delivery roll.Therefore the fault of steel strip running deviation fault can be restrained,and even corrected by means of such measures as properly determining the pressure of the delivery machine,accurately setting the position of the vertical roll,and adding a guide plate device in front of the delivery machine.In general,it is proposed that when dealing with the strip running deviation issue,all the causes should be considered comprehensively,and multi proper measures should be taken to effectively control the occurrence of the faulty phenomenon.
