The next part is devoted to the numerical simulation of the cold crucible with different number of rectangle segments. The calculation considers as load electrically non-conductive material (Al<sub>2</sub>O<sub>3 </sub>in melted form) at normal temperature. Based on the obtained results (Joule losses), it is possible to determine the distribution of power losses in the individual parts of the cold crucible and efficiency of the system. Finally, the best construction solution is selected.</span></strong>

Abstract This article aims to explain the mechanism of heat transfer between melt and cold crucible (CC) in processes referred to as induction skull melting (ISM). Several experiments were performed for this purpose. In these experiments, all relevant electrical and mechanical quantities that affect the heat transfer between the melt and the cold crucible were monitored. Firstly, this article deals with the description of the equipment used in the experiments. Aluminum oxide was considered as experimental material (EM). Therefore, the article also deals with the design of a suitable cold crucible for its melting. Subsequently, the article deals with the implementation of the experiment itself and its phases. Finally, based on the data obtained during melting processes, this paper deals with the calculation of the real heat transfer from the melt to the cold crucible. The main contribution of this article is a comprehensive view of the values of mechanical and electrical quantities that accompany the melting of the considered experimental material (EM) in the designed cold crucible. In conclusion, the values of thermal quantities obtained in the performed experiments are compared with numerical simulation.

Proper Analysis

AbstractA big interest in application of cold crucible furnace (CCF) for industrial, particularly metallurgical, processes has been observed in recent years. They are mainly utilised for melting of metal, glass and other materials. Analyses of processes that occur in such devices are performed; however, computer modelling is rarely applied. As a precise determination of the electromagnetic field distribution is essential for a proper analysis of processes in furnaces with cold crucibles, a complex 3D model development is necessary. In the paper, effects of a crucible design and current frequency on the efficiency of the induction furnace with cold crucible are presented. Numerical calculations were performed with the use of the Flux 3D professional software.
