摘要
随着冶金技术的发展,高强钢的强度得以大幅提升,单一辊系的矫直机对高强钢板的矫直能力极其有限,采用可更换辊系的双辊系矫直机是提高设备能力的有效方法.针对高强钢板的矫直特点,通过辊系能力特性分析,得出了双辊系矫直机辊系参数及其所适用的矫直范围.首先,分析了高强钢板的强化特性和反弯特性,建立了高强钢板的反弯条件;其次,从辊系的反弯能力、矫直精度和力能参数3个方面进行双辊系矫直机能力特性分析;最后,结合高强钢板的矫直特点进行实例说明.为辊系参数的选择提供了理论依据,为制定高强钢板矫直工艺提供了参考.
Abstract
With the development of metallurgical technology,the strength of high strength steel has increased significantly,which makes straighteners with a single-roll system have a very limited capacity to straighten high-strength plates.It is an effective way to improve equipment capacity by using roll system-replaceable straighteners with a double-roll system.For the straightening characteristics of the high strength plate,the roll system capacity characteristics were analyzed to conclude the roll system parameters of the double-roll system straighteners and the according straightening range.Firstly,the strengthening and reverse bending characteristics of high strength plates were analyzed,and the back bending conditions of high strength plates were estab-lished.Secondly,three roll system capacity characteristics of double-roll system straighteners were analyzed in terms of the back bending capacity,mechanical strength,and straightening accuracy.Finally,real examples were demonstrated based on the straightening characteristics of high strength plates.It provide a theoretical basis for the selection of roll systems parameters,and provides references for the development of high strength plate straightening schemes.
