Abstract
The method of steel grade determination for a steel material having a substantially circular cross-section comprise: a detection step in which while a measurement sectionincluding an irradiation sectionfor performing X-ray irradiation and a detection sectionfor detecting fluorescent X-rays is relatively moved along an outer peripheral surface of the steel materialwith respect to the steel material for a predetermined time period necessary for analysis, the steel material is irradiated with X-rays from the irradiation section, and fluorescent X-rays radiated from the steel material are detected by the detection section; a calculation step of calculating a composition of the steel material based on fluorescent X-rays detected in the detection step; and a determination step of determining a steel grade of the steel material according to the composition calculated in the calculation step.
