Abstract
The invention discloses a manufacturing method of metal alloy semi-solid rheologic slurry. Quantitative metal alloy solution is taken according to the calculation demands; a massive solid-state same alloy is added, and meanwhile, the alloy solution is quickly rotated and stirred, so that the alloy block absorbs the heat of the alloy liquid for quickly melting; the initial alloy liquid is quickly cooled due to lost of heat; when the alloy liquid is cooled, solid-state particles are generated through crystallization and solidification, and dendrites are grown; meanwhile, the applied stirring destroys the growths of the dendrites; and the spherical grinding is performed for the solid-state particles to obtain the semi-solid alloy slurry. The manufacturing method has the following advantages: high/low-temperature substances are fused; the temperature is neutralized to achieve the quick cooling purpose; the mechanical stirring is applied to circularly grind the solid-state particles; and the method has such advantages as energy conservation, consumption reduction, controllable number in each manufacturing and reduction of the production cost.
Description
Technical field
The present invention relates to a kind of manufacture method of metal alloy shaping raw material state.More particularly to a kind of metal
The manufacture method of alloy semi-solid rheological slurry.
Background technology
Metal semi-solid forming technique is in formed solid technology and liquid condition shaping technology and powder compacting skill
The postoperative a kind of brand-new rapid metallic prototyping technique for growing up, contrasts first three forming technique, their difference
Predominantly：The previously fabricated semi solid slurry containing a large amount of amorphous dendritic morphologies tissue；And set with pressure forming
Standby straight forming.The advantage of this molding is product dense structure, and high mechanical properties, decay resistance is high.
Existing semi-solid forming technology point thixotroping shaping and rheoforging, the overwhelming majority adopts thixotroping shaping skill
Art, thixotroping shaping is referred to first melts alloy raw material, then makes semi solid slurry, then cooled and solidified into
Semi-solid blank, for the quantity needed for cutting into and storage and transport, is warmed to again before the forming
530-550 degree, carries out molding.Rheoforging refers to that to make semi solid slurry after alloy raw material is melted direct
Molding is carried out into former, the advantage of this method is to leave out a step and heats process again, reduces technique
Link, saves fuel energy, and reduces cost, this method can be manufactured with direct quantitative, be it is a kind of very
The method of preferable energy saving and cost lowering.
The content of the invention
It is an object of the invention to provide a kind of fast quantification manufactures the method (neutralisation) of semi-solid alloy slurry,
With energy saving, production cost is reduced, improve the performance of product.
The present invention is achieved by the following technical solutions；According to needed for calculating, quantitative metal alloy is obtained
Solution；Block solid-state same alloy is added, and while quick Stirring alloy solution so that alloy block is inhaled
The heat fast melt of aluminium alloy is received, former aluminium alloy also cools to rapidly 530 DEG C because losing heat
- 555 DEG C, crystallization and freezing produces solid granulates and grows dendrite arm when aluminium alloy is lowered the temperature；The stirring for applying simultaneously is broken
The growth of bad dendrite arm, and rounding nodularization is carried out to solid granulates, so as to obtain semi-solid alloy slurry.
It is an advantage of the invention that merged using high/low temperature material, because in temperature and reaching the purpose of rapid cooling, apply
Mechanical agitation carries out rounding to solid granulates, and this method has energy-conservation, consumption reduction, and every time the quantity of manufacture can
The advantages of control, reduction production cost.
Specific embodiment
Embodiment 1：300 milliliters of Aluminum Alloy A356 solution is obtained, with stirring rod by one piece 80 grams of aluminum
Alloy A356 blocks are added in solution, and are quickly stirred, and aluminium block melts completely after stirring 10 seconds,
After stirring 20 seconds, complete soln surface solidifies substantially, obtains the semi solid slurry of solid rate 90%.
Embodiment 2：350 milliliters of Aluminum Alloy A356 solution is obtained, with stirring rod by one piece 120 grams of aluminum
Alloy A356 blocks are added in solution, and are quickly stirred, and aluminium block melts completely after stirring 10 seconds,
After stirring 20 seconds, solution is imported in the mould of former, straight forming obtains any surface finish, interior
Dense structure of portion, the good foundry goods of mechanical property.
Embodiment 3：550 milliliters of Aluminum Alloy A356 solution is obtained, with stirring rod by one piece 140 grams of aluminum
Alloy A356 blocks are added in solution, and are quickly stirred, and aluminium block melts completely after stirring 10 seconds,
After stirring 20 seconds, solution is imported in the mould of former, straight forming obtains any surface finish, interior
Dense structure of portion, the good foundry goods of mechanical property
In sum, the cast(ing) surface light that semi-solid metal alloy slurry directly-forming is made is manufactured using neutralisation
Clean, dense internal organization, mechanical property is good, corrosion resistance and good.Therefore, neutralisation manufacture semi-solid alloy slurry
Material not only can be energy-saving, and reduces production cost, improve product quality, and advances semi-solid forming technology
Development.
