NOUFERROUS METALLURGICAL EQUIPMENT

In response to the frequent occurrence of gear shaft breakage in the nine-roll straightener of the double-sided milling machine set, this paper systematically analyzes the working mechanism of the straightener and conducts an in-depth and comprehensive investigation into the bending deformation of the straightening rolls. On this basis, the paper rigorously selects and calculates the main parameters of the straightener, and performs a strict check analysis on the bending deformation of the working rolls. Through comprehensive research, this paper reveals the root causes of gear shaft breakage and proposes key points that should be focused on during production and use. The aim of this study is to provide operational guidance for production personnel to ensure the stable operation and efficient performance of production equipment.
