Analysis of roll system capacity characteristics of double-roll system straightener
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.
