Embodiment 1

[0017] A corrosion-resistant zinc-free pattern hot-dip zinc alloy containing Y is used on the surface of high-carbon steel at 360-450 degrees. In terms of weight percentage, the chemical composition of the alloy is: Li: 0.8wt.%, Y: 0.2wt.%, Si: 1.2wt.%, In: 1.4wt.%, Sc: 0.2wt.%, Er: 0.1wt.% .%, 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 ingot. The ingot moves down at a speed of 5-10m / min. The ingot can be used as raw material for hot-dip galvanizing for subsequent hot-dip galvanizing treatment to protect steel wires. ...

Abstract

The invention discloses a high-carbon steel surface corrosion resistant non-spangle type hot dipping Y containing zinc alloy and a machining technology thereof. The alloy is prepared from the ingredients, in percentage by weight: 0.8-1.0% of Li, 0.2-0.5% of Y, 1.0-2.0% of Si, 1.0-1.5% of In, 0.2-0.3% of Sc, 0.1-0.2% of Er and the balance of zinc. The development of the alloy can solve the phenomenon that spangles occur on the surface of a plating piece in the industrial hot dipping galvanizing process. The alloy has the characteristics of being low in production cost and convenient for scale production.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc alloy. Background technique [0002] The most widely used steel material in the industry will be corroded to varying degrees when used in environments such as the atmosphere, sea water, soil, and building materials. According to statistics, the annual loss of steel materials due to corrosion in the world can account for about 1 / 3 of its total output. In order to ensure the normal use of steel products and prolong their service life, the anti-corrosion protection technology of steel has been widely valued by people. [0003] The melting point of zinc is very low, only 419.7°C, and it can be dipped in the temperature range of 450-480°C. The generally obtained gray coating consists of two layers: the outer layer is a zinc layer, and the inner layer is an iron-zinc intermetallic compound layer. The formation of intermetallic compounds can make the metallurgical bond between ...
