Abstract
The application discloses a metal powder core type welding wire and a method for modifying the surface of a heating furnace discharge roller way, and comprises a powder core and a welding skin, wherein the powder core is composed of the following components in percentage by mass: Ni 35%-55%, Cr 15.0%-17.0%, Fe 15%-19%, Nb 4.0%-5.0%, Mo 2.8%-4.3%, TiC 5.0%-15.0%, Zr 0.5%-2.25%, and B 1.5-2.5%, and the sum of the percentage by mass of the above components is 100%; the welding skin is a nickel-based alloy strip; and the filling amount of the powder core powder in the metal powder core type welding wire is 18wt.%-25wt.%. The welding wire can be used to prepare a nickel-based alloy cladding layer on the heating furnace discharge roller way, and improve the hardness, wear resistance and corrosion resistance of the heating furnace discharge roller way. The application further discloses a preparation method of the metal powder core type welding wire and a method for modifying the surface of a heating furnace discharge roller way.
