Device for rapid elemental analysis of liquid steel in converter introduces high frequency energy produced in high frequency emission unit longitudinal through tubular hollow metal lance into gas bubble in liquid steel bath

摘要

A device introduces high frequency energy produced in a high frequency emission unit longitudinal through a tubular hollow metal lance (2-1) into a gas bubble (2-3) in a liquid steel bath, and feeding emitted light from the gas discharge produced to an optical transmission or evaluation coupling.
