Abstract：

In order to prolong the service life of pinch roll and reduce the appearance probability of impact marks on the roll surface, the surfacing layer prepared by Stellite delstain-442 wire was taken as the sample to carry out the high temperature tensile and high temperature impact tests. The microstructure and mechanical properties of surfacing layer were analyzed, and the fracture morphology was observed. The simulation and analysis model of impact stress for pinch roll was established，and the constitutive model of roll surface material was established based on the high-temperature tensile data. The influence of key factors such as warping height, strip steel speed and lead speed ratio on the maximum impact stress of roll surface was explored. The simulation results show that the warping height is the key factor affecting the maximum impact stress, with the increasing of the warping height, the maximum impact stress on the roll surface increases sharply, reaching a maximum of 1395.6 MPa. Therefore, controlling the warping height of strip steel head is an effective measure to reduce the impact stress of strip steel head on the roll surface of pinch roll.
