Description
技术领域 technical field
本实用新型涉及一种制备装置，尤其涉及一种用于半固态合金浆料制备与成形的装置The utility model relates to a preparation device, in particular to a device for preparing and forming semi-solid alloy slurry
背景技术 Background technique
半固态成形技术被公认为21世纪最有前途的轻合金近净成形技术之一，包括触变成形和流变成形两条工艺路线。经过30多年的发展，半固态成形技术经历了从流变成形到触变成形再到流变成形的螺旋式发展历程。与触变成形相比，流变成形具有流程短、废料及时当地回收、节能低耗，成为国内外研究的重点和热点。Semi-solid forming technology is recognized as one of the most promising near-net forming technologies for light alloys in the 21st century, including two process routes of thixoforming and rheoforming. After more than 30 years of development, semi-solid forming technology has experienced a spiral development process from rheoforming to thixoforming and then to rheoforming. Compared with thixoforming, rheoforming has short process, timely and local recycling of waste materials, energy saving and low consumption, and has become the focus and hotspot of research at home and abroad.
最近几年来的研究发现，不用打碎枝晶组织也可以获得细小的、近球形的半固态组织。在凝固过程初期，通过控制形核和长大过程，即将合金保持在液相线温度附近能产生大量晶核，同时限制晶核生长，能获得半固态组织。上述介绍的机械搅拌、电磁搅拌、SSR、NRC就是该理论思想的典型代表。在这些工艺中基本上都采用了“低过热度”，即先将合金熔体温度控制在合金液相线温度附近，再进行浇注或进行各种搅拌或振动。但上述工艺过多依赖于低过热度浇注。虽然低过热度浇注有利于细化晶粒，但要求浇注温度必须控制在液相线附近，对温度控制的精度和均匀性要求非常高，在实际操作中有较大困难，特别是大体积浆料微观组织的均匀性方面，这是上述工艺尚未得到工业推广和应用的重要原因。目前，流变成形研究的合金主要集中在铸造类合金，如ZL101、AZ91D等，通用铸造合金凝固区间较大，便于浆料制备，但成形后的力学性能较低。变形铝合金是广泛用于航空、航天及汽车行业的轻金属之一，目前基本上都采用触变模锻工艺进行成形，但变形铝合金流变成形的相关研究和报道很少。另外，对易燃易氧化的合金，如镁合金、Al-Li系合金的研究也是非常有限的，易燃易氧化特性对工艺和设备均提出了特殊要求，会增加设备和工艺的复杂性，上述流变铸造工艺并不能充分解决该问题，在浆料制备过程中会对合金熔体产生二次污染。Studies in recent years have found that fine, nearly spherical semi-solid structures can be obtained without breaking dendrite structures. In the early stage of the solidification process, by controlling the nucleation and growth process, the alloy can be kept near the liquidus temperature to generate a large number of crystal nuclei, and at the same time limit the growth of crystal nuclei to obtain a semi-solid structure. The mechanical stirring, electromagnetic stirring, SSR, and NRC introduced above are typical representatives of this theoretical thought. In these processes, "low superheat" is basically adopted, that is, the temperature of the alloy melt is controlled near the alloy liquidus temperature, and then pouring or various stirring or vibration is performed. But the above process relies too much on low superheat casting. Although low superheat pouring is beneficial to grain refinement, it requires that the pouring temperature must be controlled near the liquidus line, and the accuracy and uniformity of temperature control are very high, and there are great difficulties in actual operation, especially for large-volume slurry. This is an important reason why the above-mentioned process has not been industrialized and applied. At present, the alloys studied by rheological deformation are mainly concentrated in casting alloys, such as ZL101, AZ91D, etc. The general casting alloys have a large solidification range, which is convenient for slurry preparation, but their mechanical properties after forming are low. Wrought aluminum alloy is one of the light metals widely used in aviation, aerospace and automobile industries. At present, thixotropic forging process is basically used for forming, but there are few researches and reports on rheological deformation of wrought aluminum alloy. In addition, research on flammable and oxidizable alloys, such as magnesium alloys and Al-Li alloys, is also very limited. The flammable and oxidizable properties put forward special requirements for processes and equipment, which will increase the complexity of equipment and processes. The rheological casting process mentioned above cannot fully solve this problem, and will cause secondary pollution to the alloy melt during the slurry preparation process.
综上所述，世界范围内对流变成形的研究方兴未艾，上述各种制备半固态浆及流变成形工艺和设备均有其优点和缺陷，开发新的半固态浆料制备及流变成形工艺和设备仍然是半固态成形领域研究的重点，以便简化工艺、降低成本、降低浆料制备过程对合金熔体产生的二次污染、扩大适用合金种类。To sum up, research on rheological deformation is in the ascendant worldwide. The above-mentioned various semi-solid slurry preparation and rheological deformation processes and equipment have their advantages and disadvantages. The development of new semi-solid slurry preparation and rheological Forming technology and equipment are still the focus of research in the field of semi-solid forming, in order to simplify the process, reduce costs, reduce the secondary pollution of the alloy melt during the slurry preparation process, and expand the types of applicable alloys.
