Abstract
In a roller guide apparatus for guiding a steel material to be rolled into a rolling mill machine, a ratio (K/M) of an elastic constant (K [N/mm]) of the roller guide portion of a roller guide apparatus to a gradient (M [N/mm]) in a plasticity characteristic curve obtained when pressing the steel material nipped between the guide rollers in rolling is determined to be 0.5 or more, to thereby prevent the steel material from tilting between the guide rollers. As a result, dimensional accuracy in sectional shape and size of an end product can be improved, and miss-rolling can be prevented, thus producing high-quality rolled steel products without surface defects with remarkably high yield rate and productivity.
