Description
Technical field
The invention belongs to cast metals processing technique fields, and in particular to a kind of to utilize supersonic casting large-size high-quality
Aluminium alloy ingot preparation process.
Background technique
A large amount of defects of aluminum alloy materials are generated in alloy casting, and wherein quite a few defect is subsequent
It is difficult to repair in processing and heat treatment.Therefore, casting has no longer been to be only used as the molding means of material, and more importantly make
For first important link of Material quality control.The pressure processing crafts such as forge, squeeze and roll generally for needing to pass through
For the alloy deformed, semicontinuous direct water-cooling (DC) casting is to provide the major way of deforming alloy ingot blank.DC casting
Technical method is made since process flow is simple, crystallization rate is fast, avoids the turbulent flow of inclination die cast, improves the transgranular of ingot blank
Structure reduces chemical component regional segregation, reduces the tissue looseness of oxide inclusion and ingot blank center, and can be realized life
The serialization and automation of production. art process, ingot quality and productivity are high.In nearly 50 years, which, which has become, coloured gold
The particularly important deformation blank means of production in category alloy industry production, is aluminium alloy and copper alloy is also the master of magnesium alloy base
Want method.But the big ingot casting of the method production has serious segregation, nonuniform organization and inhales the problems such as hydrogen is serious.
Summary of the invention
Supersonic casting large-size high-quality aluminium alloy ingots is utilized technical problem to be solved by the invention is to provide a kind of
Base preparation process can have serious segregation, nonuniform organization with the big ingot casting that effective solution produces and inhale the problems such as hydrogen is serious.
In view of the problems of the existing technology, the present invention provides aluminium alloy ingot technology of preparation method, can significantly make to cast
The ingredient of ingot uniformly, fine microstructures and good mechanical performance.
Technical solution of the present invention the following steps are included:
(1) two supersonic generator probes are preheated, preheating temperature is about 600~700 DEG C or so, later will
The ultrasound of 2000W and 3000W is added to together in DC casting crystallizer；
(2) two ultrasonic heads are inserted in the edge melt of crystallizer in the following, depth is 100mm, melt under insertion liquid level
Treatment temperature is controlled at 720 DEG C or so, while opening supersonic generator until casting terminates.
The invention has the benefit that
1. the invention avoids nonuniform organization phenomenon caused by independent ultrasound, at the same it is respective excellent using two ultrasounds
Point, can significantly thinning solidification structure；
2. designed preparation process is simple in the present invention, ancillary equipment is not needed；
3. ingot casting crystallite dimension obtained in the present invention is tiny, even tissue.For example: such as (2000W+3000W)
After composite ultraphonic processing, edge is reduced to 150 μm from untreated 410 μm, reduces 63.4%；And 1/2 radius position is never
320 μm of processing are reduced to 76 μm, reduce 76.3%；And centre crystallite dimension is down to 98 μm from 220 μm, reduces
55.5%.Whole Fine by Ultrasonic effect is all relatively good, organizes also relatively uniform.

Specific embodiment
Presently preferred embodiments of the present invention is elaborated in conjunction with attached drawing below, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent explicitly be defined to be made to protection scope of the present invention.
It is a kind of to utilize supersonic casting large-size high-quality aluminium alloy ingot preparation process referring to shown in Fig. 1-4, including with
Lower step: (1) preheating two supersonic generator probes, and preheating temperature is about 600~700 DEG C or so, later will
The ultrasound of 2000W and 3000W is added to together in DC casting crystallizer；(2) two ultrasonic heads are inserted in the edge of crystallizer
In the following, depth is 100mm under insertion liquid level, melt treatment temperature is controlled at 720 DEG C or so melt, while opening ultrasonic wave
Device is until casting terminates.
Shown in sum up, the invention avoids nonuniform organization phenomenons caused by independent ultrasound, while utilizing two ultrasounds each
From the advantages of, can significantly thinning solidification structure, and preparation process designed in the present invention is simple, does not need ancillary equipment,
Obtained ingot casting crystallite dimension is tiny, even tissue.
The foregoing is merely better embodiment of the invention, protection scope of the present invention is not with above embodiment
Limit, as long as those of ordinary skill in the art's equivalent modification or variation made by disclosure according to the present invention, should all be included in power
In the protection scope recorded in sharp claim.
