Stage 2 Zone smelting. Fix the zirconium rod vertically in the vacuum chamber, use the high-frequency induction coil (or electron gun) as the heat source to melt one end of the rod into a melting zone, and then slowly move the melting zone from one end to the other. Zirconium is a high melting point metal with strong chemical activity.
