Experimental design of the cold crucible

Our task described in this paper is to prepare own experimental and innovative design of the cold crucibles. The measuring system which we created in our laboratory allows us an accurate evaluation of power losses. Due to measured power losses we are able to determine exact efficiency of induction system and verify previously prepared numerical simulations. Specifically, here we introduce two experimental designs. The first one is segmented cold crucible of copper tubes with drilled bottom and 3D printed collector of ABS (akrylonitrilbutadienstyren) for cooling water distributed to the tubes. The second one is milled cold crucible from one piece of solid copper cylinder with implemented 3D printed ABS collector for cooling the crucible. The function samples have been developed for use in our laboratory and for verification of numerical models, including testing of measuring system intended for our new laboratory of the cold crucible in the project SUSEN.
