试验产品和市售的包埋料和两种类型的铸造设备在这项研究中使用。研究了不同液粉比的包埋料和不同浇注系统(离心式、压力抽吸式)的可铸性,发现采用方形蜡网模样的可铸性较好。在高液粉比的包埋料中获得了良好的可铸性。在离心铸造装置中,包埋料的透气性对铸造性能的影响较小,而在压力抽吸式离心铸造装置中,包埋料的透气性对铸造性能的影响较大。用测量显微镜测量铸件边缘与金属型龈缘之间的间隙,以确定铸件的精度。可用的投资。在900 ℃的低液粉比和长时间的烧蚀条件下,获得了良好的铸造精度。研究结果表明,为使钛锆合金铸件与铸型之间具有良好的适应性,包埋料的体积膨胀率必须达到0.6%。
英文摘要
Trial product and a commercially available investments and two types of casting apparatus were employed in this study. The castability was evaluated regarding the different liquid-to-powder ratio of investment and casting system (spin type centrifugal, pressure-aspirated type).The casting behavior was found to be good by using a square wax grid pattern. An excellent castability was attained in the high liquid-to-powder ratio of investment. By using the spin type centrifugal casting apparatus, gas permeability of investment had little influence on castability, but by using the pressure-aspirated type, it exerted much influence.On the other hand, the casting accuracy was determined as a gap between the margin of the castings and the gingival margin of the metal mold measured by means of measuring microscope.The casting accuracy was found to be good by using a commercially available investment. An excellent casting accuracy was attained in the low liquid-to-powder ratio and the long burn out time at the temperature of 900゚C.The results of this study indicate that the volume expansion of 0.6% is necessary for investment to produce the good adaptability between Ti-Zr alloy castings and the mold.
