摘要：
A method for operating a converter on the basis of a direct observation of the slag-forming conditions in a vessel interior.A device for observing the vessel-interior light is disposed in a throughhole extending through the side wall of a top-blowing or top- and bottom-blowing converter to reach the vessel interior. The converter operation can be carried out at a high accuracy of the slag-amount control on the basis of this observation.
