Abstract Scope Calcium ferrite is the main binding phase for high-basicity sinter. The production and structure of calcium ferrite have greatly influence on the quality of sinter. Ultrasonic vibration was introduced into calcium ferrite melt in order to develop a new sintering process. Based on the acoustic refraction and reflection principles, ultrasonic propagation between amplitude transformer and calcium ferrite melt has been analyzed and discussed. In addition, numerical simulation of ultrasonic propagation in calcium ferrite melt has also been carried out with integration method and finite element method, respectively. The distributions of characteristic quantities including acoustic pressure and sound intensity in calcium ferrite melt were obtained, and the effects of ultrasonic power and frequency on acoustic pressure distribution were also investigated. The results show that different ultrasonic frequency makes different acoustic pressure distribution in calcium ferrite melt, while ultrasonic power has little effect on it.
