Zusammenfassung:The invention relates to the technical field of precision investment casting, in particular to a method for confirming a heat exchange coefficient of a precision casting interface and application of the method. According to the method for confirming the heat exchange coefficient of the precision casting interface, the actual molten metal temperature is compared with the simulated molten metal temperature, the actual shell temperature is compared with the simulated shell temperature, and if the temperature difference can be controlled within 10 DEG C, it is indicated that the obtained interface heat exchange coefficient is real and reliable. And the accuracy of the simulation result can be ensured only when the reliability of the interface heat exchange coefficient is verified, so that a qualified casting with higher quality can be obtained. 本发明涉及熔模精密铸造技术领域,具体而言,涉及一种精密铸造界面换热系数的确认方法及其应用。本发明提供的精密铸造界面换热系数的确认方法,通过将实际的金属液温度与模拟金属液温度作比较以及将实际的型壳温度与模拟型壳温度作比较,如果温差能够控制在10℃以内,说明所求得的界面换热系数是真实可靠的。只有验证了界面换热系数的可靠性,才能保证模拟结果的准确
