摘要： The present steel stock shaping apparatus includes a rolling apparatus which includes a plural set of 3-roll apparatuses disposed along a steel stock transferring direction in series, a precision rolling 3-roll type sizing apparatus 1 which is adapted for shaping, a carbon-material-made guide apparatus 5 which has a guide bore 50 adapted for guiding a sized steel stock "W" to a subsequent process. The inner diameter of the guide bore 50 is set so that it is larger than the outer diameter of the steel stock "W" having a circle cross section by 0.1 to 8 mm, and accordingly the clearance between an inner wall surface 55 of the guide bore 50 and the steel stock "W" is made extremely small. In addition, the axial length of the guide bore 50 is set longer, and accordingly, when a bending at the leading end of the steel stock "W" enters the guide bore 50, the bending is corrected by the inner wall surface 55 of the guide bore 50. As a result, it is possible to relieve or avoid a letter "S" shape bending which occurs when the steel stock "W" is depressed lightly with the 3-roll apparatuses.
