Description
Technical field
The present invention relates to the alloy melting technical field, a kind of specifically polynary master alloy and melting method thereof.
Background technology
In producing special brass, as adopt the method for melting once (being that whole elements use simple substance to melt in smelting furnace) can be subjected to a lot of restrictions, material mark FA6100 as my company's production, contain the very high metallic element of fusing point: Co among the FA-5806, Ni, Fe, Ti etc., its fusing point: Co 1492, Ni 1455, Fe 1537, Ti 1660, and the flame temperature of brass is between 1100 ℃～1300 ℃, under this temperature be the simple substance that is difficult to surface element in the fusing, solving this type of problem only adds before the zinc in fusion process, with top simple substance fusing, this just needs fusing time long, and it is high that temperature is wanted, its consequence is splashed when adding zinc exactly, and (zinc surface has zinc oxide greatly, the easy moisture absorption, and copper liquid is met water and just is easy to generate and splashes, What is more can quick-fried stove), each simple substance melting loss of elements is big, chemical composition stability is poor, and the production cycle is long, and unsuitable continuous production.
Shortcoming based on top melting once, adopt the technology of secondary smelting just to arise at the historic moment, its process is exactly that element and the low-melting elementary composition master alloy that fusing point is high melts earlier, in actual production process master alloy is melted with Cu, Zn etc., the target that reaches our desired each element is formed content.
The master alloy of domestic production at present is generally binary alloy as Al-Fe, Cu-Co, Cu-Ni etc., in adopting these alloy processes a lot of inconvenience is arranged also, and one, batching is complicated, the alloy number is more to be mixed up easily; Two, procurement cycle longer, let funds lie idle easily; Three, increase cost, burn out rate increases; Four, the stokehold is transferred and is added the comparison difficulty, increases the production cycle; Five, be unfavorable for continuous production, the fusing point of some master alloy is higher, as Nb-Fe.
Summary of the invention
The objective of the invention is to develop a kind of burn-off rate fast, reduce burning, yield rate height, polynary master alloy and melting method thereof that temperature of fusion is low.

A kind of melting method of five yuan of master alloys, its step is as follows:
1, put into earlier 2/3 Al ingot in smelting furnace, arrange along the furnace wall, whole Fe are put in the middle of stove, and lumpiness≤250mm of Fe is put 18%～36% Ni above, and is sturdy, after the fusing that heats up, furnace power is 150～250KW;
When 2, slight reaction sound being arranged in hearing stove, reduce the power of smelting furnace: 50～100KW, treat that total overall reaction is intact after, blowing out; In stove, add whole metal Co, after Co adds, add 1/6 Al ingot;
3, blow-on adds whole Si and remaining metal Ni successively; The fusing that heats up, furnace power is 100～250KW;
4, after Si in the solution and the whole fusings of Ni, in stove, add remaining metal A l ingot, continue to heat up and melt; Furnace power is 200～300KW;
5, be warming up to about 1300 ℃, be incubated 20～40 minutes, blowing out is stirred, slagging-off;
6, prepare cast and cast spindle.
The advantage of polynary master alloy of the present invention and melting method thereof is: when adopting this master alloy, chemical composition stability, it is more convenient to prepare burden, particularly the alloy scaling loss is few, because master alloy is to be the alloy of base with Al, the fusing point of Al is low, after other element simple substance adds, the process that an alloying is arranged, as top master alloy when fusing Al and Fe a thermopositive reaction is arranged, utilize this thermopositive reaction can well be, so the burn out rate when having reduced its melting has been saved electric power with fusings such as Ni, Co.When secondary smelting afterwards, because this master alloy fusing point is lower, can be under lower temperature and copper liquid alloying, therefore have a lot of benefits when using multicomponent alloy: 1, the stokehold material chemical composition is more stable, once inspects qualification rate by ready samples and can reach 98%; 2, cost reduces, and adopts this master alloy to realize quick fusing, has shortened the time of copper liquid in smelting furnace, has reduced burning, and yield rate improves.Material burn out rate when not adopting master alloy according to statistics reaches 13%, and after adopting master alloy, burn out rate is generally about 8%; 3, accelerated the production cycle, but continuous production, adopt melting once when fusing second stove, copper liquid in the smelting furnace must be ladled out dried, so that input simple substance Cu, Al, Fe, Co, Ni, Si melt, the fusing back adds Zn, and this method fusing time is long, in stove amount 250Kg, melt a stove and got one and a half hours.And when adopting master alloy to melt second stove, can stay a spot of copper liquid in the smelting furnace, and shortened smelting time like this, equally in 250Kg, only need 45 minutes; 4, the master alloy fusing time is short, is example with five yuan of master alloy: Al-Fe-Co-Ni-Si equally, and melting this stove (400Kg) only needs 45 minutes, and Cu-Co, Cu-Ni etc. need one hour at least; When 5, using master alloy, alloy species is few, is easy to management.
