Method for measuring and calculating oxidation burning loss rate of steel billet

The invention discloses a method for measuring and calculating the oxidation burning loss rate of a steel billet, and belongs to the technical field of metallurgical steel rolling. The method comprises the steps that oxide scale collection is carried out on a steel billet, a scanner is used for scanning and imaging according to the thickness of the oxide scale, and area segmentation, oxide scale area calculation and oxidation burning loss rate calculation are carried out on an image formed through scanning. The method can realize rapid and accurate determination of the oxidation burning loss rate of the billet, solves the problem of inaccurate determination of the oxidation burning loss rate caused by the fact that the thickness and volume weight parameters of the oxide scale need to be used in the method for indirectly determining the oxidation burning loss rate of the billet through the oxide scale, and has the advantages of simplicity, convenience, reasonable design and easiness inimplementation. 本发明公开了一种钢
