| Abstract Scope |
Molybdenum belongs to the group of refractory and alloying rare elements, which are used in industry mainly as pure metals and as alloying components in ferrous and non-ferrous alloys. The effect of the electron beam melting and refining technology on the processing of molybdenum concentrate under different process conditions is examined in the present work. The influence of the electron beam power and refining time on the composition variation, microstructures of the metal samples, and degree of refining of molybdenum is studied in order to improve the quality of the obtained metal ingots. Thermodynamic conditions of melting and refining of molybdenum and the removal efficiency of the controlled impurities are also evaluated and discussed. The results show that a maximal overall removal efficiency is seen at 17 kW beam power for a 5 min melting time and allow us to formulate requirements on the process conditions in order to improve the quality of the obtained metal material. |
