Abstract
The present invention provides a kind of aluminum grain refinement method, the when of falling stove, only adds in Al Ti intermediate alloys and Al 5Ti 1B.The present invention is not added with Al Ti B blocks in the when of falling stove, experiment proves that final grain size has no significant effect to ingot casting；So fining agent addition can be reduced, under the premise of ingot quality is ensured so as to reduce cost.
Description
Technical field
The present invention relates to aluminium alloy production technical field, more specifically to a kind of aluminum grain refinement method.
Background technology
In order to ensure ingot casting low power grain size, Al-Ti intermediate alloys, Al-Ti-B blocks at present, the refinements such as Al-5Ti-1B
Agent is substantially to be added in by the middle upper limit；Specifically, without in the alloy of dispensing value particular/special requirement 1 it is that stokehold Ti is supplied in Ti
0.012%, 5 be that stokehold supplies 0.01%.Ensure ingot casting grain size because wire feeder card group sums it up less in order to prevent, by the upper limit even
The slightly super upper limit adds in Al-5Ti-1B, and import silk occupies large percentage；Which results in the increases of production cost.
In conclusion how to realize under the premise of ingot quality is ensured, fining agent addition is reduced, to reduce cost, is
The technical issues of those skilled in the art are urgently to be resolved hurrily at present.
Invention content
In view of this, the purpose of the present invention is to provide a kind of aluminum grain refinement methods, are ensureing ingot casting to realize
Under the premise of quality, fining agent addition is reduced, so as to reduce cost.
In order to achieve the above object, the present invention provides following technical solution：
A kind of aluminum grain refinement method, the when of falling stove, only add in Al-Ti intermediate alloys and Al-5Ti-1B.
Preferably, in above-mentioned aluminum grain refinement method, what stokehold Ti was required without dispensing value 1 is alloy, in stove
Preceding Ti supplies 0.01%-0.011%.
Preferably, be alloy and 5 for 1 it is alloy in above-mentioned aluminum grain refinement method, it is Al-5Ti-1B online
Addition uses 1.0kg/ tons of Al-1.2kg/ tons of Al.
It can be seen from the above technical scheme that aluminum grain refinement method provided by the invention, the when of falling stove, only add in
Al-Ti intermediate alloys and Al-5Ti-1B.
The present invention is not added with Al-Ti-B blocks in the when of falling stove, experiment proves that final grain size has no significant effect to ingot casting；So
Fining agent addition can be reduced, under the premise of ingot quality is ensured so as to reduce cost.
Specific embodiment
An embodiment of the present invention provides a kind of aluminum grain refinement method, can under the premise of ingot quality is ensured,
Fining agent addition is reduced, so as to reduce cost.
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described, it is clear that described embodiment be part of the embodiment of the present invention rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, shall fall within the protection scope of the present invention.
Aluminum grain refinement method provided in an embodiment of the present invention, the when of falling stove, only add in Al-Ti intermediate alloys and Al-
5Ti-1B.
The present invention has made 1 system and 5 systems in founding two to reduce the experiments of Al-Ti-B blocks respectively, experiment concrete scheme and
Conclusion is shown in Table 1.
Table 1
More than testing material subsequent process does not reflect exception, and as it can be seen from table 1 is alloy for common 1 system and 5,
Al-Ti-B blocks are not added with during stove, final grain size has no significant effect to ingot casting, this conclusion is also tested in 31~37# units
Card.
In conclusion the present invention is not added with Al-Ti-B blocks in the when of falling stove, experiment proves that final grain size is without apparent to ingot casting
It influences；So fining agent addition can be reduced, under the premise of ingot quality is ensured so as to reduce cost.
Preferably, what is stokehold Ti required without dispensing value 1 is alloy, and in stokehold, Ti supplies 0.01%-0.011%.Tool
Body, supply 0.01% using in stokehold Ti.
What the present invention required Ti without dispensing value 1 is that alloy is tested by following two schemes, specific testing program and
Conclusion is shown in Table 2.
Table 2
Note：Supply dispensing value in stokehold
More than testing material subsequent process does not reflect exception, and from table 2 it can be seen that Ti required without dispensing value 1 is alloy,
Stokehold Ti supplies 0.01% and 0.012%, final ingot casting grain size no significant difference, thus 1 be alloy without dispensing value is special will
That asks matches 0.01%, and supply in stokehold.
Be alloy and 5 for 1 it is alloy in further technical solution, online Al-5Ti-1B addition use
1.0kg/ tons of Al-1.2kg/ tons of Al.Specifically, online Al-5Ti-1B additions use 1.0kg/ tons of Al.
The present invention increases card group alarm device on the wire feeder of the relatively low unit of all the degree of automation, can prevent from adding
Al-5Ti-1B.
The present invention carries out online Al-5Ti-1B Optimum Experiment, and specific testing program and result of the test are shown in Table 3.
Table 3
More than testing material subsequent process does not reflect exception, and from table 3 it can be seen that suitably reduces Al-5Ti-1B current
Usage amount, ingot casting grain size is had no significant effect.
The present invention also takes alloy part kind to replace import Al-5Ti-1B with domestic Al-5Ti-1B, further drops
Low production cost.
More than all experiments for being done and conclusion all just for square ingot casting, can again be promoted to circle ingot casting production.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other
The difference of embodiment, just to refer each other for identical similar portion between each embodiment.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use the present invention.
A variety of modifications of these embodiments will be apparent for those skilled in the art, it is as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and the principles and novel features disclosed herein phase one
The most wide range caused.
