The hot-rolled H-shaped steel has good section economy and is widely applied to the industries such as the building industry, the machinery industry, the bridge manufacturing industry and the like. When the H-shaped steel is used, the processing technologies such as butt-joint welding, assembly and the like are generally involved, so that the requirement on the appearance shape and quality of a finished product is high. At present, section steel is divided into four major categories according to the width of a flange, namely: narrow flange H-section steel (HN), middle flange H-section steel (HM), wide flange H-section steel (HW) and thin-wall H-section steel (TH). The method for expressing the specification of the H-shaped steel in the industry comprises the following steps: the height H value x the width B value x the web thickness t1 value x the flange thickness t2 value.

The basic process flow of hot rolling H-shaped steel comprises the following steps: continuous casting blank → heating → high-pressure water descaling → BD rough rolling mill → finishing mill group continuous rolling → cooling of cooling bed → straightening → sawing → inspection and bundling. In the straightening process, because of the instability of the production process, the flange of the straightened H-shaped steel is easy to bend inwards or outwards in the production process, and the national standard of the bending degree of the flange is as follows: f is less than or equal to 1.5 percent multiplied by b (F is the bending degree of the flange, and b is the half value of the width), and the bending degree F of the flange is measured as the height difference between the edge and the middle point of the flange. At present, no special measuring tool for specially measuring flange bending exists in the industry, the existing measuring mode only depends on a sample plate for measuring flange inclination, the structure of the existing measuring mode is like an H-shaped steel flange inclination measuring tool (CN 201420545389.3), and the existing measuring mode is measured and then estimated by eye (as shown in figure 1), the error is large, and the bottleneck restriction is formed on the straightening production process.
