Abstract

The invention discloses a continuous casting crystallizer copper plate plating layer and a preparation process thereof. The Ni-P crystallizer copper plate plating layer comprises a crystallizer copper plate base body, wherein an Ni-P alloy layer is plated on the surface of the crystallizer copper plate base body, and contains nickel with the mass ratio being 95 percent to 99.7 percent, and phosphorus with the mass ratio being 0.3 percent to 5 percent. The preparation process of the continuous casting crystallizer copper plate plating layer comprises the following steps of: a, preplating the base body; b, preparing composite electroplate liquid containing Ni-P materials in a plating bath; and c, electroplating the Ni-P alloy layer. Due to the adoption of the scheme, the defects of low steel production, large abrasion, frequent repair of the continuous casting crystallizer copper plate can be overcome, and the continuous casting crystallizer copper plate plating layer with uniform densification, favorable binding force, low heat crack tendency, small internal stress, excellent wear-resisting property and long life cycle is obtained.

Description

technical field [0001] The invention belongs to the technical field of crystallizers for metallurgy, in particular to a nickel-phosphorus alloy coating continuous casting crystallizer copper plate and a preparation process thereof. technical background [0002] With the rapid development of iron and steel technology, the continuous casting mold has been developed in the direction of high casting speed, high mechanical strength, good thermal conductivity, high hardness, wear resistance and corrosion resistance. However, the conventional Cr plating, Ni plating, Ni–Fe plating, Ni–Co plating, and Co–Ni plating layer, in the application process of the high-speed continuous casting mold, have large wear, heat resistance and fatigue, resulting in copper plate Unplanned off-line, increased mold copper repair times, and shortened service life. Obviously, conventional coatings can no longer meet the needs of steel companies. Although some high-tech technologies have emerged as the t...
