Vor 8 Stunden · The mass ratio of the raw materials in the two crucibles was ensured to be ~ 1:1. Throughout the heating process, Ar was continuously fed into both crucibles for atmosphere protection. When the molten metal reached the target temperature and was held for 5 min, the servomotor was switched on to drive the stirring paddles to start mechanical stirring. Subsequently, the stopper rod in crucible 1 ...
