拉伸弯曲矫直机在铝带精整中的应用研究

A Brief Analysis of Tension-Leveling Line Used for Aluminum Strip Sizing

论述了拉伸弯曲矫直机在铝带精整中的作用,参数对矫直效果的影响。拉伸弯曲矫直机属于高端有色金属精整加工设备,通过对带材的拉伸弯曲作用,能够有效地消除薄带波浪和翘曲等板形缺陷。在实际生产过程中,由于来料板型的不规则性,需要根据实际情况来调整机组参数。深入分析带材拉矫过程中拉力、矫直切入量、带材延伸率等关键技术参数对矫直效果的影响,以及各个参数的设定原则。带材的来料质量决定了延伸率的设定,在拉力达到最大的情况下,可通过调整切入量使拉矫效果达到最优。

The use, constitution of equipment, primary technical parameter and design feature of tension-leveling line used for aluminum strip were mainly introduced. Taken advantage of roller leveler and stretcher leveler, tension-leveling line cart eliminate shape defects such as herringbone buckling and improve the quality of strip efficiently in nonferrous metals sizing, which had been got a rapid expansion in aluminum sizing recently. While the equipment is working , the parameter of the need to be adjusted up on the thickness and size of the strip. The key parameter to rectify the flatness of strips, for example, tension, diameter of leveling rolls, overlap of leveling rolls ,ductility, will be mainly discussed. Incoming quality strip determines the elongation set. In the case of tension reaches a maximum, by adjusting the cutting quantity so that the straightening effect to achieve.
