在热连轧轧制过程中，工作辊作为实现轧制过程中金属变形的直接工具，由于与轧件和支撑辊接触而发生的摩擦作用以及和冷却水在高温高压下接触而发生的化学腐蚀作用而产生的磨损［１］。而工作辊的磨损情况又直接影响到热轧带钢板形的好坏。太钢１５４９ｍｍ热连轧机轧线设备是 In the hot rolling process, the work rolls act as direct tools for the deformation of the metal during the rolling process, as a result of the frictional effect due to the contact with the rolling stock and the backup roll, and the chemical corrosion that occurs with the contact of the cooling water at high temperature and pressure The resulting wear and tear [1]. The work roll wear and tear directly affect the quality of hot-rolled strip shape. TISCO 1549mm hot rolling mill rolling equipment is
