Description
Technical field
The present invention relates to a kind of preparation method of steel-smelting alloy, specifically a kind of alfer and ferro-aluminum base system column are closed
The high efficiency preparation method of gold.
Background technique
It is big except being taken on process for making for the yield for improving the active metals such as deoxidation in steel making and alloy element aluminium, magnesium, calcium
Measure outside technical measures, in recent years will above-mentioned active element and iron form alloy after use, be that raising its recovery rate is most effective
One of method.
There are mainly two types of the current techniques of the preparation method of ferro-aluminum base series alloy, the first is directly to be put into aluminium and iron
It smelts, is poured after qualified, such as number of patent application 201610198922.7, publication number CN105671412A, the applying date in intermediate frequency furnace
2016-04-01, the patent of invention of entitled " production technology of deoxidation in steel making alfer " disclose a kind of alfer
Production technology first has to smelt, and then Argon in ferro-aluminum liquid, last ferro-aluminum casting, each step of these three steps are very multiple again
It is miscellaneous, especially smelting process；Second is to use intermediate frequency furnace smelting molten steel, while toasting aluminium ingot with iron packet, will using high temperature iron liquid
Aluminium ingot punching fusing, by it is ladle-to-ladle uniformly after casting, such as number of patent application 201710361454.5, publication number CN107267813A,
Applying date 2017-05-22, patent name are that the patent of invention of " molten steel punching converts aluminium ingot and produces alfer preparation method " discloses
Aluminium ingot production alfer preparation method is converted in a kind of punching of molten steel, and the aluminium ingot after baking is converted in the punching of this method molten steel, due to aluminium ingot elder generation
600 DEG C are baked in ladle, aluminium ingot does not melt at this time, and converting by molten steel punching is completely melt aluminium ingot, due to being using steel
Aluminium ingot is converted in water punching, and molten steel unevenly causes alloy to be unevenly distributed in conjunction with aluminium ingot, needs to carry out subsequent ladle-to-ladle twice, technique
Complexity, low efficiency；In addition, this method temperature is nervous, sticked in containment wall after aluminium alloy temperature decline in ladle-to-ladle and casting process,
Reduce alloy yield and alloy packet service life；Moreover institute's aluminium metallurgy iron is deposited in and is easy to dusting in atmosphere, cannot fully meet makes
With requiring.
Summary of the invention
The technical problems to be solved by the present invention are: how to overcome in the prior art ferro-aluminum base system column alloy preparation technology it is multiple
Miscellaneous, the shortcomings that recovery rate is low, at high cost and ferro-aluminum natural storage is easy to dusting.
In order to solve the above technical problems, the present invention proposes the high efficiency system of a kind of alfer and ferro-aluminum base series alloy
Preparation Method, technical solution are as follows:
A kind of high efficiency preparation method of alfer, comprising the following steps: (i) use intermediate frequency furnace or electric furnace by scrap melting
At molten steel, remove slag stand-by；(ii) aluminium ingot is put into alloy packet, and toasts and is melted into molten aluminum；(iii) the conjunction of molten aluminum will be housed
Jin Bao is transported under intermediate frequency furnace or electric furnace fire door, and directly being rushed to be blended into alloy packet with the molten steel in intermediate frequency furnace or electric furnace becomes alloy
Liquid, and poly- slag and slagging-off；(iv) alloy packet handling to casting machine is poured, completes the preparation of alfer.
A kind of high efficiency preparation method of ferro-aluminum base series alloy, comprising the following steps: (i) use intermediate frequency furnace or electric furnace
By scrap melting at molten steel, remove slag stand-by；(ii) aluminium ingot is put into alloy packet, and toasts and is melted into molten aluminum；(iii) need to
The corresponding metal of other conjunction elements for being added into ferro-aluminum is added in molten aluminum or molten steel, makes its fusing；Other conjunction elements are corresponding
The rule that metal is added are as follows: if the melting point metal is more than or equal to 1000 DEG C, which is added in molten steel；If the metal
Then the metal is added in molten aluminum less than 1000 DEG C for fusing point；(iv) the alloy packet equipped with molten aluminum is transported to intermediate frequency furnace or electric furnace fire door
Under, directly being rushed to be blended into alloy packet with the molten steel in intermediate frequency furnace or electric furnace becomes aluminium alloy, and poly- slag and slagging-off；(v) by alloy
Packet handling is poured to casting machine, completes the preparation of ferro-aluminum base series alloy.
In this way, aluminium ingot is first melted into molten aluminum by the present invention in alloy packet, is then directly rushed with molten steel and convert molten aluminum, aluminium can
Be distributed in steel very uniformly, without repeatedly ladle-to-ladle, if desired add other conjunction elements, then the property of can choose by fusing point height
Addition molten steel in (such as manganese) make its fusing, (such as magnesium, calcium) in lower melting-point addition molten aluminum is made into its fusing, simple science；
It can be seen that present invention science is converted by " liquid " with rushing for " liquid ", process step design is ingenious, and simple science is easy, especially
It is that when needing to add other conjunction elements, ingenious can more select, one side process is reduced, and low energy consumption, and it is at low cost, on the other hand produce
High-efficient, the more other methods of production efficiency improve 50-100%, finally also solve ferro-aluminum powder during natural storage in air
The problem of change.
The technical solution that the present invention further limits is:
The high efficiency preparation method of alfer or ferro-aluminum base series alloy above-mentioned, step (i) in, the weight of steel scrap is to need
The 20-80% of the alfer weight of preparation, step (ii) in, the weight of aluminium ingot is the 20- for needing alfer weight to be prepared
80%, the sum of steel scrap and the weight of aluminium ingot are the alfer weight of preparation.
The high efficiency preparation method of alfer or ferro-aluminum base series alloy above-mentioned, by scrap melting at molten steel, control
Liquid steel temperature is 1580-1700 DEG C；Aluminium ingot is melted into molten aluminum, control temperature of aluminum liquid is 670-1100 DEG C；Molten steel directly rushes
Being blended into alloy packet becomes aluminium alloy, and control aluminium alloy temperature is 1150-1550 DEG C.Liquid steel temperature is set as 1580-1700
