[0012] 1. Preparation of zinc-antimony master alloy: Add metal zinc into the melting pot, use electric heating pot to melt the zinc, after the zinc is melted, cover a layer of charcoal powder on the surface of the zinc liquid, heat up to 640-660°C and then add metal Antimony, fully melted and cast ingots to form a zinc-antimony master alloy containing 40% antimony, and the single weight of the zinc-antimony master alloy is controlled to ensure accurate ingredients during secondary smelting;

[0013] 2. Production of zinc-antimony alloy: Calculate the amount of metal zinc and zinc-antimony master alloy that should be added according to the volume of the melting pot, add metal zinc into the melting pot, heat up to 510-530°C after the zinc is melted, and then add antimony 40% zinc-antimony master alloy, fully melted and cast ingot to form zinc-antimony alloy.

[0014] The main components of the zinc-antimony alloy are mass percent: 9-11% of antimony and 89-91% of zinc.

Embodiment 1

[0016] Add 600Kg metal zinc into the melting pot, use electric heating to melt the zinc, after melting, cover a layer of charcoal powder on the surface of the zinc liquid to ensure that the zinc is not oxidized, add 400Kg metal antimony after heating up to 640°C, fully Cast ingot after melting to form zinc-antimony master alloy. Control the single weight of the zinc-antimony master alloy to 19.5-20.5Kg to ensure accurate ingredients during the secondary smelting. The master alloy contains 39.84% antimony.

[0017] According to the volume of the melting pot, calculate the amount of metal zinc and zinc-antimony master alloy that should be added. First, add 1200 Kg of metal zinc into the melting pot, heat up to 510°C after melting, add 400 Kg of master alloy, and cast ingots after fully melting. A zinc-antimony alloy with an antimony content of 9.8% is produced.

Embodiment 2

[0019] Add 600Kg metal zinc into the melting pot, use electric heating to melt the zinc, after melting, cover a layer of charcoal powder on the surface of the zinc liquid to ensure that the zinc is not oxidized, add 400Kg metal antimony after heating up to 650°C, fully Cast ingot after melting to form zinc-antimony master alloy. Control the single weight of the zinc-antimony master alloy to 19.5-20.5Kg to ensure accurate ingredients during the secondary smelting. The master alloy contains 39.91% antimony.

[0020] According to the volume of the melting pot, calculate the amount of metal zinc and zinc-antimony master alloy that should be added, first add 1200 Kg of metal zinc into the melting pot, heat up to 520°C after melting, add 420Kg of master alloy, cast ingots after fully melting, and produce A zinc-antimony alloy with an antimony content of 10.12%.

Abstract

The invention provides a production method of zinc-antimony alloy. The production method of zinc-antimony alloy comprises the following steps: adding zinc metal into a melting pot, melting zinc by utilizing an electrical heating pot body, after zinc is molten, covering the surface of the molten zinc with charcoal powder, warming to 640-660 DEG C, adding antimony metal, and ingoting after the antimony metal is fully molten to form zinc-antimony intermediate alloy; according to volume of the melting pot, calculating amounts of the zinc metal and the zinc-antimony intermediate alloy which are needed to be added, adding the zinc metal into the melting pot, after the zinc metal is molten, warming to 510-530 DEG C, then adding the zinc-antimony intermediate alloy, and ingoting after the zinc-antimony intermediate alloy is fully molten, so as to generate the zinc-antimony alloy. The production method of the zinc-antimony alloy has the advantages that a secondary smelting method is adopted, the problems that smelting speed is low and oxidation is serve in a zinc-antimony alloy production process are solved, and the problem of composition segregation is also solved as the smelting speed is high when the zinc-antimony alloy product is produced, so that the production method of the zinc-antimony alloy is applicable to being applied in the field of zinc alloys.

Description

technical field [0001] The invention relates to a metal smelting method in the field of nonferrous metal metallurgy, in particular to a production method of a zinc-antimony alloy. Background technique [0002] Zinc is a white and slightly blue-gray metal with a hexahedral crystal form, stable at room temperature and dry air, and forms a layer of off-white dense basic zinc carbonate film on the surface in humid air to prevent the internal zinc from continuing. Oxidation and corrosion, so it is widely used in the anti-corrosion coating of steel. Hot-dip galvanizing is currently the most widely used atmospheric corrosion-resistant coating for steel. When a small amount of aluminum, antimony, lead and other elements are added to the zinc liquid, it not only changes the zinc liquid Surface tension, and beautiful spangles are formed on the surface of the coating, which is favored by users. The antimony content of the existing zinc-antimony alloys for galvanizing does not exceed ...
