Problems solved by technology

[0004] At present, the master alloys produced in China are generally binary alloys such as: Al-Fe, Cu-Co, Cu-Ni, etc. There are also many inconveniences in the process of using these alloys. First, the ingredients are complicated, and the number of alloys is large and easy to confuse; 1. The procurement cycle is long, and it is easy to backlog funds; 3. Increase the cost and increase the burning loss rate; 4. It is difficult to add before the furnace, which increases the production cycle; 5. It is not conducive to continuous production, and some intermediate alloys have higher melting points, such as Nb -Fe

Abstract

The invention relates to a multivariate interalloy and a smelting method thereof. AI is taken as a base, other metals comprising Mn, Si, Fe, Ni, Co, Nb and Ti are added in certain ratio, and the AI and the added two or more metals form a ternary interalloy, a quaternary interalloy and a quinary interalloy. The interalloy and the method have the advantages that: 1, a stokehold material has stable chemical composition, the first time quality can reach 98 percent; 2, the cost is reduced, flash melt is realized, the time for liquid copper in a smelting furnace is shortened, metal oxide is reduced and the casting yield is improved; 3, the production period is quickened and the interalloy can be continuously produced; 4, the interalloy has short melting time, and the quinary interalloy AI-Fe-Co-Ni-Si is taken as an example, only thirty-five minutes is needed to melt one furnace of the quinary interalloy AI-Fe-Co-Ni-Si (400kg), while at least one hour is needed to melt Cu-Co, Cu-Ni and the like; and 5, when the interalloy is used, the alloy types are few, so the management is easy.

Description

technical field [0001] The invention relates to the technical field of alloy smelting, in particular to a multi-element master alloy and a smelting method thereof. Background technique [0002] In the production of special brass, if the method of one-time melting (that is, all elements are melted in a melting furnace with simple substances) will be subject to many restrictions. For example, the material codes FA6100 and FA-5806 produced by our company contain metals with high melting points. Elements: Co, Ni, Fe, Ti, etc., its melting point: Co 1492, Ni 1455, Fe 1537, Ti 1660, while the flame-out temperature of brass is between 1100°C and 1300°C, it is difficult to melt at this temperature For the simple substance of the above elements, to solve this kind of problem, the only way to solve this problem is to melt the above simple substance before adding zinc in the smelting process, which requires a long melting time and high temperature. There is zinc oxide, which is easy t...
