Embodiment 1
[0018] A high-strength and corrosion-resistant zinc alloy containing V suitable for hot chamber die-casting when smelted at 450 degrees. In terms of weight percentage, the chemical composition of the alloy is: Ba: 1.0wt.%, Ru: 0.4wt.%; V: 0.9wt.%, In: 0.6wt.%, Co: 0.8wt.%, Sb: 1.9wt.% .%, the balance is zinc. The preparation method of the alloy: add the above-mentioned raw materials into the atmosphere-protected induction furnace, and use a silicon carbide crucible; induction heat to 450 degrees to form an alloy solution, and use the electromagnetic stirring effect to fully stir for about 10 minutes; put the alloy liquid in After standing at 450°C for 10 minutes, it is cast into the equipment at the same level as the hot top for semi-continuous casting into the required square and round ingots. The ingot moves down at a speed of 12m / min. The ingot can be used as casting raw material for pressure casting in the subsequent process to prepare zinc-barium alloy castings with comp...
