Submersible lance

Refractory insertion pipe which is used for the metallurgical treatment of metal melts. For pig iron treatment, for example, a desulfurization agent is injected into the melt onto the bottom of the pig iron ladle by means of a carrier gas through the submersible lance, whereas for steel production, for example, argon gas as the homogenizer for the melt or solid matter for the refinement alloying is added to the melt through a submersible lance (s. a. Injector).
