ASSESSMENT OF THE LOADING OF ROLLING CAGE ELEMENTS CONNECTED BETWEEN EACH OTHER THROUGH THE ROLLED STRIP
Abstract
Dynamic processes in continuous rolling mills are usually determined by the nature of technological loads in the rolling transition zones. In the future, these processes extend to a significant part of the stable sections of the technological process, thereby creating additional loads on the drive elements of the machines. The behavior of the strip at the moment when the metal fills the deformation site of the rolling mill is determined by the ratio of the speeds of the strip and the rolls being rolled, the shape of the front end of the strip, and the influence of neighboring cells- tey. In this work , dynamic and mathematical models of the behavior of a group of crates have been developed, taking into account the peculiarities of the work of the roughing group of rolling crates of a continuous-billet mill.
