【摘要】 板带钢生产在国民经济中起着重要的作用,轧制规程是板带生产主要的工艺技术内容。板带冷连轧生产过程中,合理的轧制规范是保证冷连轧机机组优质、高产、低耗不可缺少的条件,随着轧制技术的发展,单靠经验方法制订轧制规程已不能满足生产需要,轧制规程的制订应该提升到理论高度,使之具有普遍的指导意义。本文依据某厂1420mm冷连轧机组实际生产情况,主要完成了以下几项工作与研究:首先全面分析、提炼了适合生产实际的主要轧制模型,并回归得到冷轧常用的11种钢种的变形抗力幂函数形式回归模型;然后分析了常规轧制规程优化设计方法中,所选用的循环逼近迭代法容易导致计算发散的原因,并提出应用极限差值法进行迭代计算,通过与其它方法以及现场实际轧制参数对比,验证了该方法的优越性;编制了冷轧常用22种规格带钢的指数函数形式的能耗模型,并根据能耗曲线进行轧制规程优化设计;最后编制了基于Delphi的轧制规程优化仿真系统,应用上述模型与计算方法设计轧制规程并仿真。更多还原

【Abstract】 Plate and strip production plays an important role in national economy, and the rolling schedule is the main technological substance in plate and strip production. In the production procedure of the cold rolling, it is important to offer a rational rolling schedule for the high quality, high yield and low energy consumption. Presently, the schedule based on the experience is not satisfying. Therefore in order to offer a more rational schedule, the field experience should be concluded into theory for more extensive significance.Based on the 1420mm five tandem cold rolling mill of Baosteel, the research works in this paper are presented as follows:Firstly, the main rolling models are analyzed in detail, and models adapt to practical procedure are summarized. At the same time, the model of deformation resistance in the type of power function for 11 kinds of steels is given.Secondly, the reason of the divergence of the traditional iterative method using in the design of cold rolling schedule for strip is analyzed, and it indicates that the method of max difference can solve this puzzle, and the comparative experiment is illustrated to testify the method.Thirdly, the energy consumption curves of some kinds of normal steels are outlined in the style of index function, and the optimization schedule base on it is also given.Lastly, the rolling schedule optimization emulation system based on Delphi 7.0 is illustrated.更多还原
