Abstract The flatness roll is the key equipment for the production of high-end cold-rolled strip. Its surface performance is very important to ensure the surface quality of strip products and improve its own service life. To improve the hardness and wear resistance of the surface of the flatness roll, the surface strengthening treatment is carried out by means of the laser cladding iron base wear-resistant alloy. The properties of the surface strengthened by laser cladding and hardened by quenching are compared through experiments. The results show that the wear resistance of the cladding layer is at least 20.9% higher than that of the quenching layer under the condition of satisfying the hardness requirement. A new way for the research and development of surface strengthening technology of cold-rolled strip steel flatness roll has been opened up.
