双机架平整机延伸率分配模型研究

针对双机架平整机的实际特性,在保证成品机械性能的前提下,以基态弯辊力下带材的出口板形最好为准则,建立了一套双机架平整机机架间延伸率分配数学模型,同时给出了相应的张力与轧制压力设定方法,并将其应用到生产实践,大大提高了平整产品的板形精度,创造了良好的经济效益,具有较大的推广应用价值。

Research on Elongation Distribution Model of Two-stand Skin Miller

Against the practical characteristics of two-stand skin miller and on the premise of assurance of finished product mechanical property, a set of elongation distribution model about two-stand skin miller was established on the criterion that exit shape of the strip was best under the ground state bend-roll forces. At the same time, the setting method of corresponding tension and rolling pressure was provided and applied to production practice. It greatly increases the shape precision of planished products, creates better economic returns for the factory and has a rather large promotion and application values.
