针对中色奥博特铜铝业有限公司意大利米诺六辊UC轧机轧制黄铜板带出现的严重板形问题,探讨了造成宽度为650 mm的C2680黄铜板形差、弯辊力大、加工硬化严重等问题的原因.结果表明,通过控制辊系精度、中间辊抽动位置及轧制工艺调整可以显著改善宽幅黄铜轧制的板形,控制辊系精度保证偏心率不超过0.01 mm,中间辊的位置约为带卷加工率的2倍,保证来料的软硬性能(硬度低于70 HV),即可降低合金的变形抗力,提高合金的板形质量,并彻底消除加工硬化印.
針對中色奧博特銅鋁業有限公司意大利米諾六輥UC軋機軋製黃銅闆帶齣現的嚴重闆形問題,探討瞭造成寬度為650 mm的C2680黃銅闆形差、彎輥力大、加工硬化嚴重等問題的原因.結果錶明,通過控製輥繫精度、中間輥抽動位置及軋製工藝調整可以顯著改善寬幅黃銅軋製的闆形,控製輥繫精度保證偏心率不超過0.01 mm,中間輥的位置約為帶捲加工率的2倍,保證來料的軟硬性能(硬度低于70 HV),即可降低閤金的變形抗力,提高閤金的闆形質量,併徹底消除加工硬化印.

In order to solve the serious shape problem of brass plate by Mino six roll UC mill. The factors for poor shape, high roll bending force and high work hardening of C2680 sheet with width of 650 mm are analyzed. The results show that the shape of wide brass sheet can be dramatically improved by controlling rollers precision, in-termediate rolls position and rolling process. Controlling the rollers precision is applied to guarantee the eccen-tricity ratio to be lower than 0.01mm. The value of intermediate rolls position is about two times as processing rate, which ensure the hardness of raw materials to be lower than 70 HV. The deformation resistance can be de-creased by improving the quality of shape of brass sheet and eliminating work hardening imprints.
