Unbending strains of strands in multi-points unbending profiles of low head continuous casters, which will serve to direct rolling of high temperature cast slabs, were studied through the newly developed mathematical model and the accurate simulation experiments giving the following results.
(1) Agreement between calculated strains with this mathematical model and experiments is excellent, while the conventional equation needs to be corrected.
(2) The distribution of unbending strain is decided mainly by the arrangement of rolls rather than by stress-strain characteristics or rigidity distribution of a strand.
(3) The effects of roll arrangements on the characteristics of strain distribution are as follows.
In a one-point unbending profile, the maximum strain increment is about a half of the value estimated by the conventional equation.
In a continuous multi-points unbending profile the maximum strain increment agrees with the conventional equation, while it is about half as large as that of the conventional equation in an intermittent multi-points unbending profile.
