Resistance heating is commonly used with aluminum and copper alloys. Vacuum induction melting (VIM) uses an induction heating source within a sealed, air-evacuated chamber. Often, crucibles that ...

God, Zangwill claimed, was using America as “a crucible” to melt the “fifty” barbarian tribes of Europe into a metal from which He can cast Americans. Today, the melting pot metaphor is ...

Arc melting furnace can melt metals and alloys at over 3000°C with the aid of the electric arc between the non-consumable tungsten electrode and the copper crucible. Therefore, the arc furnace is a ...

They analyzed, in particular, how to regulate the discharge of oxygen from the quartz crucible into the silicon melt during the silicon growth phase in a Czochralski (CZ) puller, which is commonly ...

The furnace is also able to produce the alloys of some reactive metals such as Ti and Zr in a water-cooled copper crucible using the ISM coil. By controlling the chamber pressure and the temperature, ...
