Description
Technical field
The invention belongs to metallurgical technology fields, in particular to a kind of coverter pig aluminium system deoxidation carburetting alloy and its manufacturer
Method.
Background technique
In production during carbon steel, homlolgation can be generally taken.By taking Q235B as an example, converter tapping carbon can reach
0.07~0.09%, it also needs to add carburant after furnace.The characteristics of carburant is light, easily floating.If molten steel is without LF refining
Processing, carburant is not easy to be uniformly distributed in molten steel, needs the stirring that argon station is strong, this will result in the loss of temperature and necessary
It heats up into LF, causes the failure of converter " on straight " technique.To complete converter " on straight " technique, best bet is in deoxidation
Be done directly carburetting simultaneously, but since carburant is light, common process when producing alloy it is difficult to ensure that alloy homogenization.
Summary of the invention
The purpose of the present invention is to provide a kind of coverter pig aluminium system deoxidation carburetting alloy and its manufacturing methods, after fusing
Carburant is added in molten aluminum, carburant is uniformly stirred into using electromagnetic force, guarantees the homogenization of alloy, to be produced in homlolgation
During medium carbon steel, the alloy is added after Converter, deoxidation can be completed, and can enter and complete carburetting inside molten steel,
The disadvantage for individually adding carburant to float on molten steel is avoided, the processing time is shortened, meets the medium carbon steel on straight to converter in temperature
Needs on whole-process control.
The invention is realized by the following technical scheme:
A kind of coverter pig aluminium system deoxidation carburetting alloy, it is characterised in that: the constituent of alloy is aluminium, carbon, iron, with alloy
Total weight on the basis of, the weight percent of each ingredient are as follows: aluminium 40%~50%, carbon 18%~22%, iron 28%~48%, close
Goldc grains degree is 30~50mm.
A kind of manufacturing method of coverter pig aluminium system deoxidation carburetting alloy, which is characterized in that specific steps are as follows:
(1) raw material uses aluminium ingot, carburant, the ingot iron that granularity is 5~12mm；
(2) aluminium ingot is melted in crucible induction furnace, carburant and industry is added according still further to the ratio of alloy finished product content
Pure iron, while applying spiral electromagnetic agitation, spiral electromagnetic agitation 150~250A of electric current, 2.5~4Hz of frequency are completely solidifying to alloy
Stop spiral electromagnetic agitation after Gu；
(3) fritter for being 30~50mm at granularity by alloy breaks down using crusher, packaging.
Aluminium system deoxidation carburetting alloy of the invention be used for Converter after deoxidation and carburetting, according to the recovery rate of different stoves,
Oxygen content and deoxidation degree calculate the additional amount of alloy, complete the addition of the alloy in high hopper or hopper.
Carburant and iron block are stirred into the molten aluminum after fusing using spiral electromagnetic agitation by the present invention, enable the carburant of floating
It enough stirs into molten aluminum, ensure that the homogenization of alloy, during homlolgation produces medium carbon steel, add the alloy after Converter
Enter, deoxidation can be completed, and can enter and complete carburetting inside molten steel, avoid individually plus carburant floats on molten steel, be not easy
The disadvantage of fusing shortens the processing time, makes the rapid carburetting of molten steel, meets the needs that converter medium carbon steel directly goes up temperature.

Specific embodiment
Below with reference to embodiment, invention is further described in detail.
As shown in Fig. 1,5,6 and 7, spiral electromagnetic agitation can be by different densities, the metal bath of different components, Huo Zhejin
Belong to melt to mix with solid particle.Since spiral electromagnetic agitation can push metal bath to flow on three-dimensional,
Not only there is circumferential rotational flow in melt, while there is also the flowing of vertical direction, thus metal bath or metal bath
Composition with the mixture of solid particle can be relatively uniform, and the composition distribution of mixture and the correlation of density drop significantly
It is low, it is uneven that density difference bring ingredient can be effectively reduced.Molten metal 3 is contained in crucible 2, in spiral magnetic stirrer 1
Under the action of, molten metal 3 also has upper and lower, inside and outside flowing while circumferential flow.As shown in Fig. 2,3 and 4, traditional electromagnetism
Aluminium alloy 3 mainly does circulatory motion when stirring, and the interior-outer of molten metal 3, previous-next exchange are fewer.And use spiral electromagnetic agitation
When, molten metal 3 not only has circumferential movement, while being also exacerbated in radial and axial flowing, thus has stirring well
Effect, solidification while can effectively facilitating molten metal 3 reduce ingot casting central defect, can also mitigate slab gravity segregation journey
Degree.
