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。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 established.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.
