Abstract
The present invention discloses a kind of aluminium zinc for galvanizing, and by weight, component and the content of described aluminium zinc are as follows: aluminium 4.5 ~ 5%, strontium 0.1 ~ 0.15%, germanium 0.02 ~ 0.03%, and surplus is zinc.Aluminium zinc of the present invention plating alloy weight is adopted to reach 400 ~ 420g/m
2.Plated layer compact, evenly.
Description
Technical field
The invention belongs to galvanizing field, be specifically related to a kind of aluminium zinc for galvanizing.
Background technology
Steel product is widely used in the every field of national life, a large amount of iron and steel scrap is caused every year because of corrosion, at present, corrosion both at home and abroad in order to prevent iron and steel to lack goods, usually in the zinc layers of its plated surface last layer as sacrificial anode, iron-zinc alloy layer that a small amount of aluminium can eliminate zinc-iron interface is added in pure zinc coating, plating piece is made to have more processibility, when the aluminium added reaches 5%, coating has the corrosion protection speciality of pure zinc and fine aluminium coating concurrently, but, when aluminium content is more than 0.03%, the probability that steel surface does not plate increases, cause that thickness of coating is too thin reaches processing requirement, have to adopt " two plating method " to thicken coating.
Summary of the invention
The problem that when object of the present invention solves existing hot-dip aluminum zinc, plating amount is low, provides a kind of aluminium zinc being easy to plate.
It is as follows that the present invention realizes the technical scheme that above-mentioned purpose adopts:
For an aluminium zinc for galvanizing, by weight, component and the content of aluminium zinc are as follows: aluminium 4.5 ~ 5%, strontium 0.01 ~ 0.015%, germanium 0.02 ~ 0.03%, and surplus is zinc.
The preparation method of above-mentioned aluminium zinc, comprises the following steps: add in melting furnace by zinc, aluminium, strontium, germanium by proportional quantity, and at temperature is 600 ~ 650 DEG C, fusing evenly, then casting.
Beneficial effect: adopt aluminium zinc of the present invention plating alloy weight to reach 400 ~ 420g/m
2.Plated layer compact, evenly.
Embodiment
Below in conjunction with embodiment, the present invention is described in further details.
Embodiment 1
Be added in smelting furnace by 50kg aluminium ingot, 949.7kg zinc ingot metal, 0.1kg strontium grain and 0.2kg germanium grain, furnace temperature rises to 600 DEG C, after having dissolved, and mechanical stirring is even, then pours into strip.
Embodiment 2
Be added in smelting furnace by 45kg aluminium ingot, 954.55kg zinc ingot metal, 0.15kg strontium grain and 0.3kg germanium grain, furnace temperature rises to 650 DEG C, after having dissolved, and mechanical stirring is even, then pours into strip.
Adopt the alloy of above-described embodiment 1 to carry out hot dip process to steel wire, when steel wire gait of march is 12m/min, one time plating alloy weight can reach 400 ~ 420g/m
2.And adopt 5% conventional aluminum-zinc alloy, when other processing condition are all identical, one time plating alloy weight only has 150 ~ 170g/m
2.Adopt the steel wire accelerated corrosion test after aluminium zinc hot dip of the present invention: 5%NaCl solution, test temperature 35 ± 2 DEG C, test and have no red rust in 170 hours.
Claims (2)
1., for improving an aluminium zinc for a galvanizing plating amount, a plating amount is 400-420g/m
2, it is characterized in that: by weight, component and the content of described aluminium zinc are as follows: aluminium 4.5 ~ 5%, strontium 0.1 ~ 0.15%, germanium 0.02 ~ 0.03%, and surplus is zinc.
2. described in claim 1 for the preparation method of the aluminium zinc of galvanizing, comprise the following steps: add in melting furnace by zinc, aluminium, strontium, germanium by proportional quantity, at temperature is 600 ~ 650 DEG C, fusing is evenly, then casting.
