Problems solved by technology

[0003] The surface of molten zinc is rapidly oxidized at high temperature, resulting in a large amount of oxidized slag, resulting in a waste of resources, hindering the operation and increasing the workload
And the produced zinc oxide will adhere to the surface of the plated parts before the coating grows, which will cause quality defects of the plated parts, especially reduce the surface bonding force between the coating and the substrate, so that the quality of hot-dip products cannot be guaranteed
Especially in the production process of continuous hot-dip steel wire, because the steel wire passes through the molten zinc solution rapidly and continuously, similar to continuous stirring in the zinc solution, the molten zinc solution is more likely to be oxidized, and a large amount of oxidized slag is produced on the surface , wasting resources while reducing the quality of hot-dip galvanized products
[0004] At present, there is no method to improve the oxidation resistance of the zinc solution in the field of hot-dip galvanizing, but when using galfan hot-dip (zinc-5% aluminum-rare earth alloy), it can slightly improve the oxidation resistance of the zinc solution, but the improvement effect is limited

Embodiment 1

[0031] Using a vacuum induction melting furnace as a heating device, put 95 parts by mass of zinc ingots into a graphite crucible and heat it to 430°C to melt, and at the same time put 4.5 parts by mass of metal hafnium into a graphite melting crucible with a quartz jacket and heated to Melt at 2250℃, then add 0.5 parts by mass of lanthanum to the hafnium liquid. After the lanthanum is melted, add the hafnium liquid to the zinc liquid, and immediately spread the charcoal with a thickness of 15cm on the liquid surface. The particle size of the charcoal is 0.3 cm. It is naturally cooled to 600°C and cast out to obtain hot-dip galvanizing antioxidant.

Embodiment 2

[0033] Using a vacuum induction melting furnace as the heating device, the zinc ingots of 96 parts by mass are put into a graphite crucible and heated to 440°C to melt, and 3 parts by mass of hafnium metal is put into a graphite melting crucible with a quartz jacket and heated to Melt at 2280℃, then add 1 part by mass of lanthanum and yttrium to the hafnium liquid (the ratio of lanthanum to yttrium is arbitrary), after the lanthanum and yttrium are melted, add the hafnium liquid to the zinc liquid, and immediately spread on the liquid surface after being completely added For charcoal with a thickness of 17cm, the particle size of charcoal is 0.5cm. It is naturally cooled to 650°C and cast out to obtain a hot-dip galvanizing antioxidant.

Embodiment 3

[0035] Using a vacuum induction melting furnace as the heating device, put 97 parts by mass of zinc ingots into a graphite crucible and heated to 500°C to melt, and at the same time, put 2.2 parts by mass of metal hafnium into a graphite melting crucible with a quartz jacket and heated to Melt at 2300℃, then add 0.8 parts by mass of cerium to the hafnium solution. After the cerium is melted, add the hafnium solution to the zinc solution. After the cerium is melted, the liquid surface is immediately covered with charcoal with a thickness of 18cm. The particle size of the charcoal is 0.4 cm. It is naturally cooled to 700°C and cast out to obtain hot-dip galvanizing antioxidant.

Abstract

The invention provides a hot galvanizing antioxidant and a preparation method and application thereof. The hot galvanizing antioxidant is prepared from, by mass, 95-98 parts of zinc, 2-5 parts of hafnium and 0.5-1 part of a rare earth element. The hot galvanizing antioxidant is applied to hot galvanizing, oxidization of galvanizing zinc can be effectively restrained, the zinc ingot utilization rate can be increased, and the production cost is reduced; and meanwhile, the flowability of the galvanizing zinc can be increased, the wettability of a galvanized layer can be improved, the galvanizing zinc is evenly and flatly spread on the surface of a plating part, the uniformity of the plating layer is improved, the conditions such as needle holes and skip plating are effectively eliminated, and the plating layer obtains better surface quality. Good economic benefits and wide application prospects are achieved.

Description

Technical field [0001] The invention relates to the field of hot-dip plating, in particular to a hot-dip galvanizing antioxidant and a preparation method and application thereof. Background technique [0002] Hot-dip galvanizing, also known as hot-dip galvanizing, is a method for steel components to be immersed in molten zinc to obtain a metal coating. Hot-dip galvanizing is a simple and effective steel protection process, which is widely used in steel protection. In recent years, with the rapid development of my country’s economy, especially the development of the construction industry, automobile industry, and transportation, the market demand for steel hot-dip galvanized products has greatly increased, and the market has put forward higher standards for the quality of steel hot-dip galvanized products. Requirements. [0003] The molten zinc is rapidly oxidized on the surface at high temperatures, resulting in a large amount of oxidized slag, resulting in waste of resources, hind...
