Problems solved by technology

[0003] The disadvantage of the above-mentioned existing practice is that the content of nickel in the zinc-nickel alloy is not high enough, and the adhesion of the coating is relatively general, so it is difficult to meet the requirements of manufacturers for the adhesion strength of the zinc coating on the surface of steel under special circumstances.
However, since the galvanizing temperature is about 440°C, the melting point of nickel is much higher than this temperature; when the content of nickel in the zinc-nickel alloy is increased, because the time required for nickel melting is prolonged, it is equivalent to indirectly reducing the temperature of the galvanizing plant. production capacity; and once the nickel is not fully melted due to insufficient heating time, it will greatly affect the surface quality and aesthetics of the plated parts

Embodiment 1

[0024] Embodiment 1: A zinc-nickel alloy, comprising components and their corresponding mass percentages: Ni 0.5%, the balance being Zn and unavoidable impurities. Specifically, see the attached figure 1 , the zinc-nickel alloy is prepared by the following steps:

[0025] S1. The following raw material composition is weighed according to the target composition ratio of the alloy. The content of Ni is 0.5% by weight percentage, and the balance is Zn and unavoidable impurities. Among them, the raw material of Zn is zinc ingot No. 0, and the raw material of Ni is sponge nickel or metal powder with a purity exceeding 99.99%. When Ni uses metal powder with a purity exceeding 99.99% as a raw material, the particle size of the Ni powder can be 20 μm. When nickel sponge is used as the raw material of Ni, nickel sponge is a nickel-based porous sponge-like structure with a large specific surface area, which can achieve low temperature, fast speed, and does not require molten salt prot...

Description

technical field [0001] The invention relates to the technical field of nonferrous metallurgy, in particular to a zinc-nickel alloy and a preparation method thereof. Background technique [0002] Steel hot-dip galvanizing anticorrosion is an economical, practical and effective method, which has been widely used in the field of steel processing for many years. When the "active" steel containing silicon is hot-dip with ordinary zinc bath, due to the high alloying speed between the zinc in the zinc bath and the "active" steel at the interface, the coating is super thick, which shows that the coating adhesion is poor, It also makes the surface of the coating dull and dull. In order to solve this problem, the currently known technology is to add 0.05 to 0.14% (wt) nickel metal in the zinc solution to form a zinc-nickel alloy solution. Hot-dip zinc-nickel alloy is the current solution to the problem of hot-dip silicon-containing steel. effective method. It can effectively inhibi...
