Abstract
A thermally galvanizing alloy with no or low poison contains such as Al (0.30-0.45 Wt.%), Sb (0.04-0.12) and Zn (rest) and is made up through preparing Zn-Al intermediate alloy at 450-700 deg.C, preparing Zn-Sb intermediate alloy at 550-650n deg.C, and alloying molten Zn, Zn-Al alloy and Zn-Sb alloy.
Description
The present invention relates to a kind of zinc base alloy and manufacture method thereof.
Steel anti-corrosive one of the most extensive effective means is pot galvanize or hot-dip galvanized alloy, is more common as adopting the Zn-Al-Pb ternary alloy to use as the hot dip alloy, but plumbous to human body murder by poisoning and to the pollution of environment, limited above-mentioned alloy purposes.
The object of the present invention is to provide a kind of low toxicity or nontoxic zinc base alloy, thereby to overcome the requirement that above-mentioned shortcoming satisfies the user.
One of feature of the present invention is that described zinc base alloy is made up of Zn+AL+Sb, wherein closes the Al of 0.30-0.45% (weight), the Sb of 0.04-0.12% (weight), and surplus is Zn.
Two of feature of the present invention is that the production method of described zinc base alloy is that (1) is under 450-700 ℃ of temperature, preparation contains 4-20%Al, the Zn-Al master alloy of 96-80%Zn, (2)) under 550-650 ℃ of temperature, preparation contains 2-11%Sb, the Zn-Zb master alloy of 98-89%Zn, (3) zinc ingot metal is melted under 420-500 ℃ of temperature, then in the zinc liquid that respectively Zn-Al and the adding of Zn-Sb master alloy of required composition is melted, also can earlier the Zn-Al master alloy be added in the zinc liquid of fusing, and then add metal Sb in same zinc liquid.
The manufacturing of hot-dip galvanized alloy of the present invention is undertaken by following step.(1) under 420-500 ℃ of temperature, with the zinc ingot metal fusing, (2) add the Zn-Al and the Zn-Sb master alloy of required composition in the zinc liquid of fusing, (3) melting, stirring zinc liquid 3-4 hour, and (4) drag for slag, (5) alloy liquid zinc ingot metal.
Process flow sheet of the present invention is seen accompanying drawing.
The invention has the advantages that to provide a kind of low toxicity or nontoxic zinc-base alloy, and it is plumbous right to reduce Human body is poisoned and to the pollution of environment.
