圧延理論の英語

すなわち、前記延伸圧延機の各スタンドで前記素鋼管を圧延するに際して、該素鋼管の肉厚分布を理論的に決定するようにした。例文帳に追加

That is, when rolling the steel tube stock with each stand of the stretch reducer, the thickness distribution of the steel tube stock is theoretically determined. - 特許庁

そして、当該摩擦係数μを用いて、ロール扁平率が前記設定値以下の様々な圧延条件にて、圧延理論値（Ｑ１，Ｑ２，・・・，Ｑｎ）を求め、予め式構造の定められた関数Ｆの定数を、前記圧延理論値をフィッティングするように求める。例文帳に追加

By using the friction coefficient μ, the theoretical rolling values (Q1, Q2, ..., Qn) are obtained under various rolling conditions where the roll flatness is equal to or less than the preset value, and the constant of the function F having the predetermined expression is obtained so as to fit the theoretical rolling values. - 特許庁

本発明は、絞り圧延機で生じる管端部の厚肉化を予め延伸圧延機で圧下、相殺するに際して、その圧下量を理論的に定め、従来より製管歩留りを向上させる鋼管端部の肉厚制御方法を提供することを目的としている。例文帳に追加

To provide a control method for the thickness of the end parts of a steel pipe by which the rolling reduction is theoretically determined and the yield of pipe-making is improved than that of a conventional method when the thickening in the end parts of the pipe which is generated in a stretch reducer is canceled by preliminarily reducing the thickness with an elongator. - 特許庁

先ず、ロール扁平率が予め定めた設定値以下の金属板材を用いて、実験により正確な塑性係数Ｑａを求め、この実測値Ｑａと圧延理論値Ｑｂとが一致する摩擦係数μを算出する。例文帳に追加

The correct plasticity coefficient Qa is experimentally obtained by using a metal plate with its roll flatness being equal to or less than the preset value, and a friction coefficient μ in which the measured value Qa and the theoretical rolling value Qb is matched with each other. - 特許庁
