HFW焊管活套連續(xù)供料與生產效率的關系分析

Analysis of Relationship between Accumulator Continuous Feeding and Productivity in HFW Pipe Manufacturing Process

摘要: 分析了HFW焊管生產過程中臥式螺旋活套的連續(xù)性供料與生產效率之間的關系，認為保證焊接質量和生產效率的關鍵在于活套的連續(xù)供料，而活套的連續(xù)供料主要受帶鋼對接時間、鋼卷長度、快速充料速度和軋機運行速度等參數的制約。根據分析結果整理出相關參數的計算公式，為實際生產應用提供理論依據；并就保證活套連續(xù)供料的問題提出了解決措施。

Abstract: Analyzed in the essay is the relationship between continuous feeding by the horizontal spiral accumulator and the productivity in the HFW pipe manufacture process.As a result, it is identified that the critical step to ensure both welding quality and the productivity of the operation line is keeping continuous feed by the accumulator.And whether continuous feeding operation can be ensured is subjected to such parameters as strip butting time, coil length, fast-charging speed and running speed of the rolling mill, etc.Based on the above mentioned analysis, the calculation formula for related parameters is derived, being regarded as the theoretic basis for application to actual production activities.Finally, measures to ensure the accumulator continuous feeding are proposed.
