GRAPHICAL FACTORIZATION OF THE INFLUENCE THE TECHNOLOGICAL FACTORS ON CONTINUOUS ROLLING

Metal rolling on modern mills takes place continuously with band tension. If the interstand tensions are adjusted according to the results of scientifically based calculations, it is possible to provide more rational, from the point of view of energy saving, processing conditions. A generalized graphical factorization for the technological parameters of continuous rolling the grade was performed, which allows determining the cause-and-effect relationships of kinematic and power processes, as well as changes in the shape of workpeaces in processing. 
The construction of the graphic model begins with the use of the Ishikawa diagram with a clear definition the technological factors of continuous rolling with tension. Solving the problem of tension mode management research in the continuous rolling process is carried out for chosen 5M factors: (М2) Management; (М3) Measurement; (М4) Material; (М5) Machines; (М6) Manufacturing. Features of the model include a qualitative determination on a research basis of the influence the factors on energy saving, taking into account the longitudinal stability of rolling. When constructing the diagram using semantic communications, the results of a preliminary analysis the influence of technological factors during continuous rolling on modern mills with the inclusion of wire blocks are summarized. Visualization of factorization is achieved by the graphical modeling. 
The graphical model can be used as a basis in the following analytical modeling of the rolling process for operating conditions in manufacturing, ensuring its adequacy. It is actual the use of modern theoretical methods of calculating the stress state along the entire length of the workpeaces. For the future, it will be the use of the finite element method with the subsequent determination of the quantitative influence of technological parameters. For example, how the friction conditions in the neighboring zones of deformation will doing on the stressed state of the rolled metal.
