A Numerical Analysis of Strains in Slabs and Forces on Rollers in the Straightening Zone of Continuous Casting Machine

Abstract

A numerical method has been developed to improve mechanical analysis of straightening process in continuous casting, preceded by discussion on shortcomings involved in forgoing methods.
Characteristics of the straightening revealed by this method are
(1) Starting end of slab strand exerts excessive force on rollers in the straightening zone,
(2) The above force becomes much smaller in the steady state of casting,
(3) Curvature of the strand is largely in agreement with that of roller alignment but with some offalignment in the steady state of casting,
(4) Straightening of the starting end cannot completely be made, leaving complicated deformation of the end slab.
