Abstract
For the remelting of titanium or zirconium, the electroslag remelting method is used. To prevent any reaction of the melt with oxygen or nitrogen, the remelting is performed in an inert gas atmosphere. Fluorspar with an addition of calcium oxide is used as the slag forming substance. This calcium oxide dissolves in the fluorspar and reacts with oxygen, nitrogen and hydrogen in the titanium, so that the reactive metal is purified of these substances.
