Abstract The BTW1/Q345R composite plate not only possesses dual performance advantages of high strength and wear resistance but also contributes to reduced energy consumption and production costs. This paper proposes a novel rolling process based on corrugated rolls for the preparation of wear-resistant steel BTW1/Q345R composite plates.Macroscopic plate shape, microscopic structure, and mechanical properties of the post-rolled wear-resistant steel BTW1/Q345R composite plates are analyzed using techniques such as Electron Backscatter Diffraction (EBSD). The results indicate that the composite plate obtained through rolling with a 3# corrugated roll exhibits a yield strength of 550 MPa, tensile strength of 705 MPa, elongation at break of 17.57%, and shear strength of the composite interface at 242 MPa. Notably, the rolling process with a 3# corrugated roll yields the best combination of tensile mechanical performance and interface bonding performance for the composite plate.
