Abstract

The invention discloses a zinc alloy ingot and a preparing method thereof. The zinc alloy ingot comprises, by weight, 3.5%-4.3% of aluminum, 0.8%-1.2% of copper, 0.04%-0.07% of magnesium, 1.0%-1.5% of manganese, 0.05%-0.1% of molybdenum, 0.03%-0.08% of nickel, 0.02%-0.15% of boron, 0.08%-0.12% of zirconium and the balance zinc and unavoidable impurities. The preparing method of the zinc alloy ingot includes the steps of preparing, pretreating, smelting, pressure casting, drawing, annealing and the like. The zinc alloy ingot and the preparing method thereof have the advantages that the zinc alloy ingot is resistant to wearing, corrosion and high temperature, the influence of iron element impurities is effectively reduced, the surface is even and attractive, cost is low, and the certain promotional value is achieved.

Description

technical field [0001] The invention relates to the field of alloy technology, in particular to a zinc alloy ingot and a preparation method thereof. Background technique [0002] Zinc alloy is an alloy composed of zinc and other elements. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloy has low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, and the residual waste is easy to recycle and remelt. In recent years, as the requirements for corrosion resistance and appearance quality of steel products have become higher and higher, many zinc alloy coatings have been developed in the field of hot-dip galvanizing. Among them, the most researched and the most outstanding achievement is the research on zinc-aluminum alloy coating. However, most of the currently used zinc alloys are poor in wear resistance and corrosion resistanc...
