Embodiment 1
[0017] A high thermal conductivity zinc alloy containing Ca and Mg for hot-dip galvanizing in a ceramic crucible at 360-450 degrees. In terms of weight percentage, the chemical composition of the alloy is: Ca: 0.2wt.%, Sn: 1.0wt.%, Mg: 1.0wt.%, Ge: 0.2wt.%, Cu: 0.2wt.%, Mo: 0.1wt .%, Ni: 1.2wt.%, W: 1.0wt.%, 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 heating to 500-600 degrees to form an alloy solution, and use the electromagnetic stirring effect to fully stir for about 10 minutes; put the alloy The liquid is kept at 500-600 degrees for 10 minutes and then cast into the equipment at the same level as the hot top for semi-continuous casting into the required round ingots. The speed of the ingot moving down is 5-8 / min. The ingot can be used as hot-dip galvanizing raw material for subsequent hot-dip galvanizing treatment to protect s...
