縱向內(nèi)應(yīng)力是由于軋件內(nèi)部的拉伸不均勻引起的，這使得軋件寬度上施加的張力有向上的差異。所謂目標帶鋼形狀曲線，是指在帶鋼的外張力作用下，沿帶鋼寬度方向的張力差所形成的曲線。它不僅反映了帶鋼的真實形狀，而且是現(xiàn)代軋機板形控制的重要手段。在日常生產(chǎn)中，常用的曲線主要有平曲線、正弦曲線和余弦曲線等。
　　The longitudinal internal stress is caused by the uneven tension inside the rolled piece, which makes the tension applied on the width of the rolled piece upward difference. The so-called target strip shape curve refers to the curve formed by the tension difference along the strip width direction under the external tension of the strip. It not only reflects the real shape of strip, but also is an important means of shape control in modern rolling mill. In daily production, the commonly used curves are mainly flat curve, sine curve and cosine curve.

　　底部兩側(cè)的正弦曲線翹曲，有利于減少軋制過程中帶鋼斷裂的概率，適合冷軋薄板的生產(chǎn)。余弦曲線兩側(cè)上翹，軋件兩側(cè)中間緊松，適用于生產(chǎn)毛坯或厚板。平曲線適用于生產(chǎn)特種薄板或鋁箔軋制。
　　The sine curve warping on both sides of the bottom is beneficial to reduce the probability of strip fracture during rolling, and is suitable for the production of cold-rolled sheet. Both sides of the cosine curve are warped, and the middle of the two sides of the rolled piece is tight and loose, which is suitable for the production of blanks or thick plates. Flat curve is suitable for the production of special sheet or aluminum foil rolling.
