A Study of the Parameters for Hot Straightening of Thick Steel Plates on a Roller Straightening Machine

Resumo

We examine the parameters for hot straightening of steel plates, taking into account deformation of the metal on the rollers during alternating bend process, as well as the temperature and strain rate. The calculations showed that deformation, temperature, and strain rate have a significant impact on the bending moments and the straightening force; these must be taken into account in the design and operation of roller straighteners. The approach used for straightening steel plates is used to calculate the operating parameters of plate straightening machines.
