ABSTRACT:
Chromium-containing steels are decarburised without substantial losses of chromium by blowing simultaneously into the molten steels, below the surface thereof, water vapor and a non-oxidising gas such as hydrogen, nitrogen, argon or helium. A triple feed tuyere is used, with the water vapor in the central or intermediate tube, and the non-oxidizing gas in the other inner tube, and with a protective fluid in the outer tube. The proportions of water vapor and non-oxidizing gas are selected so that the temperature of the steel bath is thereby controlled and also the desired decarburisation occurs without substantial chromium loss.
