Rolling deformation of high-intensity and thin tinplates and roll profile of a skin pass mill

摘要: 以某廠鍍錫板連退機組雙機架HCM平整機為研究對象,理論分析結合有限元仿真和現場實驗,對硬質薄規格鍍錫板的平整軋制變形行為進行了研究,揭示了硬質薄規格鍍錫板平整時軋制力偏大、實際延伸率達不到設定目標延伸率以及實物板形質量較差的原因,確定了相應的解決問題的技術思路.在此基礎上,運用基于有限元仿真的輥形設計方法和軟件,研制了新的中間輥端部輥形.生產應用結果表明,該中間輥端部輥形能夠有效地減輕壓靠、穩定實現設定的目標延伸率且實際平整軋制力降低10%～20%,而且還可以根據需要在正常平整軋制力下使實際延伸率增加0.1%～0.2%.Abstract: The rolling deformation of high-intensity and thin tinplates was investigated for an HCM skin pass mill by FEM method and field experiment. Some reasons for higher actual roll force and poor flatness were revealed, and the solutions to these problems were determined. Based on the FEM analysis and roll profile design software, a new polynomial curve of the intermediate roll profile was proposed. Practical applications showed that the forced-contract was mitigatory, i. e., the actual roll force decreases by 10% to 20% and the actual elongation increases by 0.1% to 0.2%.
