中 文 摘 要
近年来，我国的钢铁工业经历了前所未有的发展，板带材的产量也逐年增长。随着人们对板带材的质量要求不断提高，中厚板矫直机作为改善板材质量的关键设备也显得越来越重要。但是由于我国对矫直技术的研究起步较晚，因此对矫直技术的研究仍存在不足之处，导致国内的矫直机在矫直质量、矫直效率及自动化水平上与国外相比仍有一定的差距。

式矫直原理，本文对中厚板矫直机进行了工艺参数分析，通过理论分析，分析了包辛格效应和中性层偏移对矫直过程的影响，建立了截面分层的矫直内弯矩算法，并建立了十一辊矫直机矫直解析模型，从而可以计算出辊式矫直机的各种力能参数，并给出了矫直过程中截面上各种应力与应变的分布规律。然后通过有限元分析软件Marc对辊式矫直过程进行了模拟。最后，对中厚板辊式矫直机进行了实验研究，设计了矫直力的测试装置，并对矫直力进行了现场测试。通过对比我们发现，矫直过程的分层计算方法与有限元模拟得到的矫直力与实测值差距很小，证实了分层计算方法与有限元模拟的可行性。
总之，本文采用分层计算、有限元模拟以及实验研究等方法对辊式矫直过程进行了研究，其结果可以对我国中厚板辊式矫直技术的发展提供理论依据和科学指导。同时，本文采用的分层计算方法为矫直理论的进一步发展提供了新的研究手段。

ABSTRACT
ABSTRACT
In recent years, steel industry in our country undergo a unprecedented development, the production of strip also keeps a higher increase each year. Along with the unceasing enhancement of users to the strip quality requirement, the leveler as a key equipment for ensuring strip quality, determine the productivity and quality of the strip. But because of the slow development of straightening theory, the weak links of in researching straightening technology, the straightening equipments in the country still has a gap compared with foreign.

This topic takes straightening project in testing laboratory as a backing, has conducted the research to technologies of strip roller straightened. According to the straightening theory and the roller straightening principle, this paper carried on processing parameter analysis by using roller straightened to straightening strip, analyzed the influence of the packet singh effect and neutral layer migration to the process of straightening, the calculation model of leveling process is developed. By the calculation mode, all kinks of straightening force was worked out, and also given the stress and strain distribution laws of leveling process. Finally, a straightening force testing equipment was designed, and straightening force was tested. The gap of straightening force among layered calculation, the test value and layered calculated value, the results confirmed the correctness of layered calculation.
In short, this paper combined analysis calculation, layered calculation and experimental methods to study the process of strip roller straightening, the result could provide the development of strip roller straightening technology.
