Abstract

The emerging demands on higher steel grades call for improvements in the operation of production units and a corresponding increase in automated processes, and therefore international steel producers require viable functions. The avoidance of slag carry-over to secondary metallurgy processes is essential for achieving steel grade qualities and reducing alloys in order to compensate slag residues in the downstream unit. The automatic tapping procedure in BOF converters will be supported by the implementation of reliable measurements used in high-end steel plants. Automatic tapping will help to achieve the following: Reduced slag carry-over, improved yield, increased reproducibility, improved working environment and safety and operation with minimum possible crew. The automatic tapping procedure is capable of being implemented in new or retrofitted installations.
