Embodiment 1
[0024] The hot-dip galvanized aluminum rare earth alloy used for hot-dip galvanizing of steel components has a composition of 0.008% (wt) Al; 0.006% (wt) RE; the rest is zinc and unavoidable impurities.
[0025] The ingot type of hot-dip galvanized aluminum rare earth alloy is a rectangular zinc ingot body 1 with two symmetrical ear warps 3 "T", and the upper plane and the bottom of the zinc ingot body 1 are planes. One of the ear hooks 3 is provided with a hanging hole 2 . The four sides of the zinc ingot body 1 are inclined planes, the upper cross section of the zinc ingot body 1 is larger than the lower cross section, the ingot weight is 900kg, the length L of the ingot shape is 1160mm, the width B is 580mm, and the height H is 260mm.
[0026] The above-mentioned hot-dip galvanized aluminum rare earth alloy ingot is used to hot-dip galvanize steel components, and the zinc alloy ingot is melted into a zinc bath. The obtained zinc bath has stable and uniform alloy element con...
