Abstract

The application relates to the field of rolling mill equipment, and specifically discloses a sliding plate for a rolling mill and its surface cladding and surfacing welding process. The sliding plate for rolling mill includes a sliding plate body, the surface of the sliding plate main body is provided with a cladding layer, and the cladding layer includes the following components in mass percentage: C 0.18-0.23%, Cr 13-15%, Mn 1.2-1.5%, Si 0.5‑0.8%, Mo 0.25‑0.35%, Ni 0.25‑0.35%, Al 0.8‑1.5%, Co 0.1‑0.3%, Cu 0.8‑1.5%, V 0.8‑1.5%, P≤0.03%, S≤0.03% , Nb 0.01‑0.03%, Ti 0.005‑0.01%, and the balance is Fe. In the present application, a cladding layer is formed on the surface of the main body of the skateboard by laser cladding, so that the wear resistance of the skateboard surface is improved.

Description

technical field [0001] This application relates to the field of rolling mill equipment, more specifically, it relates to a sliding plate for rolling mill and its surface cladding and overlay welding process. Background technique [0002] The rolling mill is the equipment that realizes the metal rolling process, and the metal material is rolled into a rolled material with a certain cross-sectional shape. The sliding plate is one of the important components of the rolling mill. It is installed on the archway frame and the roll bearing seat, so that the roll bearing seat slides on the archway frame, and is used to protect the archway frame and the bearing seat working surface. [0003] The surface quality and service life of the sliding plate also directly affect the stability of the rolling process, the operating efficiency of the rolling mill, the quality of the steel plate and the production cost. During the rolling process, the slide plate is subjected to high rolling forc...
