Abstract: For KOCKS mill, dynamic characteristics of roll system are the main factors influencing the quality of rolled products. In this paper, the rigid-flexible-coupling virtual prototype of roll system is established. Under the limit condition of rolling 25 mm-40Cr bar, dynamic analysis on whole rolling process including idling, biting steel, steady rolling state and throwing steel is executed to obtain the time-domain dynamic characteristic curves of roll system based on rigid-flexible-coupling virtual prototype. In addition, free modal analysis on the roll system is also carried out under pre-stressing force. The research verifies the rationality of the prototype and provides a data platform for manufacturing of physical prototype.

Keywords: KOCKS mill; roll system; rigid-flexible coupling; vibration analysis; product quality; rolled products; idling; biting steel; steady rolling state; throwing steel; virtual prototyping; modal analysis.
