Description of the Related Art When a wire or bar is used, for example, when it is turned and used, a wire or bar wound into a coil for turning (hereinafter referred to as "bar wire") or bent is generated. It is necessary to straighten the existing rods and wires. Further, the bar wire rod having the surface flaw needs to be bent in order to perform centerless grinding.

う問題があった。As a device for correcting the bending of a rod wire,
Various devices are known, but in the case of difficult-to-machine materials such as titanium and titanium alloys, the Young's modulus is about 1/2 that of ordinary steel and stainless steel, so it takes about 2 It is necessary to add double the distortion. For this reason, there has been a problem that cold straightening cannot be adequately straightened and cracks and the like occur during straightening.

According to Japanese Patent Laid-Open No. 0220, there is known a method in which a metallic material in a tensioned state is straightened by heating while running along a heating furnace.

長手方向での断面寸法に変動が生じる。However, since the metallic material heated by this method is only the portion located in the heating furnace, the cross-sectional shrinkage ratio in the longitudinal direction of the material is not uniform due to the temperature variation in the longitudinal direction of the metallic material. As a result,
Variation occurs in the cross-sectional dimension in the longitudinal direction.

い。On the other hand, according to Japanese Patent Laid-Open No. 6-154929, there is known a method in which a wire is heated electrically and then both ends thereof are fixed, and the wire is straightened by a contracting force during cooling.
However, in this method, since the tension applied to the wire is only the contracting force associated with cooling, it cannot be sufficiently corrected.

ため、生産効率の低下及び表面酸化ロスが生じる。Further, according to Japanese Patent Laid-Open No. 58-41642, the material to be processed is heated electrically and the dimensional change of the material is measured. There is known a method of performing plastic working by applying a tension to a work material when the value exceeds. However, in this method, it is difficult to straighten a material having no phase transformation, and when the phase transformation temperature is higher than the straightening temperature, the material is overheated, resulting in a decrease in production efficiency and surface oxidation loss.
