Description
本发明属金属材料领域，特别涉及一种用于细化铝及铝合金晶粒的铝-钛-碳中间合金的制备方法。The invention belongs to the field of metal materials, and in particular relates to a preparation method of an aluminum-titanium-carbon intermediate alloy used for refining aluminum and aluminum alloy grains.
铝-钛-碳中间合金的研究一直是国内外学者十分关注的重要课题。但因碳在铝液中溶解度极低，很难制成铝-钛-碳中间合金。直至1986年后，Banerji和Reif提出了采用强力搅拌方法合成铝-钛-碳中间合金以后才使之成为可能。如文献(Metallurgical Transactions，1986，17A：2127-2137)报道了关于钛和碳在铝熔体中形成TiC颗粒的研究，0.5～2％预热的石墨颗粒被强力搅拌到1175℃以上的铝-钛合金(含钛5～10％)熔体中。该方法的最大缺点是工艺复杂，成本高，因而难以实现规模生产，其应用受到限制。专利申请号为98119378的中国专利报道了另一种铝-钛-碳中间合金的生产方法：将铝-钛合金熔化至1000℃-1200℃，加入活化剂，再加入石墨粉，然后浇注成锭状铝-钛-碳中间合金。该工艺的特点是先制备出铝-钛合金，然后再将之重熔，并需加入活化剂，其工艺也较复杂，且成本高。还有文献(Trans.Nonferrous Met.Soc.China，2000；Vol.10，No.1)报道了用K2TiF6和石墨粉生产铝-钛-碳中间合金的方法，该方法的缺点是生产过程中放出大量的KF和AlF3等有毒气体，污染环境，并且中间合金中往往含有盐类夹杂物等，从而污染了铝合金。The research on aluminum-titanium-carbon master alloy has always been an important topic of great concern to scholars at home and abroad. However, due to the extremely low solubility of carbon in molten aluminum, it is difficult to make aluminum-titanium-carbon master alloys. It was not possible until after 1986 that Banerji and Reif proposed the synthesis of aluminum-titanium-carbon master alloy by means of strong stirring. For example, the literature (Metallurgical Transactions, 1986, 17A: 2127-2137) reported a study on the formation of TiC particles from titanium and carbon in aluminum melts. 0.5-2% preheated graphite particles were vigorously stirred to an aluminum- Titanium alloy (containing 5-10% titanium) melt. The biggest disadvantage of this method is that the process is complicated and the cost is high, so it is difficult to achieve large-scale production, and its application is limited. Chinese patent application number 98119378 reports another production method of aluminum-titanium-carbon master alloy: melting the aluminum-titanium alloy to 1000°C-1200°C, adding an activator, then adding graphite powder, and then casting it into an ingot aluminum-titanium-carbon master alloy. The feature of this process is that the aluminum-titanium alloy is prepared first, and then remelted, and an activator needs to be added. The process is also complicated and the cost is high. There are also literature (Trans.Nonferrous Met.Soc.China, 2000; Vol.10, No.1) reported the method of producing aluminum-titanium-carbon master alloy with K 2 TiF 6 and graphite powder, the disadvantage of this method is the production During the process, a large amount of toxic gases such as KF and AlF 3 are released, polluting the environment, and the master alloy often contains salt inclusions, etc., thereby polluting the aluminum alloy.
本发明的目的在于克服现有技术的不足，提出一种简便且无污染的铝-钛-碳中间合金的制备方法。The purpose of the present invention is to overcome the deficiencies of the prior art, and propose a simple and pollution-free preparation method of aluminum-titanium-carbon master alloy.
一种铝-钛-碳中间合金的制备方法，是通过以下方式实现的，A method for preparing an aluminum-titanium-carbon master alloy is achieved in the following manner,
(1)首先按重量百分比为：铝73.00-99.00％，钛0.80-25.00％，碳0.01-3.00％准备好工业纯铝、工业纯钛和石墨粉原料；(1) firstly by weight percentage: aluminum 73.00-99.00%, titanium 0.80-25.00%, carbon 0.01-3.00% ready industrial pure aluminum, industrial pure titanium and graphite powder raw materials;
(2)在感应炉中将工业纯铝熔化至1100℃-1350℃，然后同时加入工业纯钛和石墨粉，保温0.5-20分钟后降温至浇注温度；(2) Melt industrial pure aluminum to 1100°C-1350°C in an induction furnace, then add industrial pure titanium and graphite powder at the same time, keep warm for 0.5-20 minutes and then cool down to pouring temperature;
(3)直接浇注成锭或通过连铸连轧设备制备成线材。(3) Direct casting into ingots or preparation into wire rods through continuous casting and rolling equipment.
本发明由于不需预先制备铝-钛中间合金，且无须强力搅拌，因而制备工艺简单、生产效率高、成本低；由于不用K2TiF6，所以无氟化物污染，是一种绿色环保型的制备方法。且制备的产品无盐类夹杂物，可使待细化的铝合金的废品率降低15-35％，挤压型材的速度提高15-20％；且具有细化效果的高效性和遗传性，适合于大规模工业生产和应用。Since the present invention does not need to prepare aluminum-titanium master alloy in advance, and does not need strong stirring, the preparation process is simple, the production efficiency is high, and the cost is low; since K 2 TiF 6 is not used, there is no fluoride pollution, and it is an environmentally friendly Preparation. And the prepared product has no salt inclusions, which can reduce the scrap rate of the aluminum alloy to be refined by 15-35%, and increase the speed of extrusion profiles by 15-20%. Suitable for large-scale industrial production and application.
下面给出本发明的一个最佳实例：A best example of the present invention is given below:
(1)首先按重量百分比为：铝94.00％，钛5.50％，碳0.50％准备好工业纯铝、工业纯钛和石墨粉原料；(1) at first be by weight percentage: aluminum 94.00%, titanium 5.50%, carbon 0.50% get ready industrial pure aluminum, industrial pure titanium and graphite powder raw material;
(2)在感应炉中将工业纯铝熔化至1270℃；然后同时加入工业纯钛和石墨粉，保温10分钟后降温至浇注温度850℃；(2) Melt industrial pure aluminum to 1270°C in an induction furnace; then add industrial pure titanium and graphite powder at the same time, keep warm for 10 minutes and cool down to pouring temperature of 850°C;
(3)直接浇注成锭或通过连铸连轧设备制备成线材。(3) Direct casting into ingots or preparation into wire rods through continuous casting and rolling equipment.
