Plate Roller Straightening Process Algorithm Model Amendment

In recent years, steel industry in our country undergo a unprecedented development, the production of strip also keeps a higher increase each year. Along with the unceasing enhancement of users to the strip quality requirement, the leveler as a key equipment for ensuring strip quality, determine the productivity and quality of the strip. But because of the slow development of straightening theory, the weak links of in researching straightening technology, the straightening equipments in the country still has a gap compared with foreign.This topic takes straightening project in testing laboratory as a backing, has conducted the research to technologies of strip roller straightened. According to the straightening theory and the roller straightening principle, this paper carried on processing parameter analysis by using roller straightened to straightening strip, analyzed the influence of the packet singh effect and neutral layer migration to the process of straightening, the calculation model of leveling process is developed. By the calculation mode, all kinks of straightening force was worked out, and also given the stress and strain distribution laws of leveling process. Finally, a straightening force testing equipment was designed, and straightening force was tested. The gap of straightening force among layered calculation, the test value and layered calculated value, the results confirmed the correctness of layered calculation.In short, this paper combined analysis calculation, layered calculation and experimental methods to study the process of strip roller straightening, the result could provide the development of strip roller straightening technology. Meanwhile, the layered calculation methods used in this paper provides a new means of research for the further development of the straightening theory.
