Abstract：The main production process and equipment characteristics of H-beam were introduced, and the cause of excessive flange slope in the production line of a large H-beam in a domestic steel plant was analyzed.Combined with the characteristics of equipment work and field tracking, it showed that the flange inclination of H-beam flange exceeding the standard could be divided into two cases of excessive pass length and only excessive head of rolled piece. The excessive length was related to the relative position of the rolling line of the finishing mill and its front and back swinging roller table. The deviation of the flange at the head of the rolled piece was associated with the sawing process equipment situation. At the same time, the rolled piece temperature, straightening of the slope had a certain impact on the flange inclination. Through the implementation of the corresponding measures, the flange inclination could be effectively controlled.
