Resumo
OXYGEN CONVERTERS HAVE PROGRAMS TO DETERMINE LANCE-TO-BATH HEIGHT (DBL) FROM REFERENCE MEASUREMENTS OF THE BOTTOM AND BATH LEVELS. THESE REFERENCES ARE LENGTH MEASUREMENTS THAT REPRESENT A VOLUME. HOWEVER, THEY ARE PUNCTUAL AND GENERALLY TAKEN AS A REFERENCE TO THE CENTER OF THE CONVERTER. THIS ARTICLE INVESTIGATES THE EFFECT OF THE UNEVEN RISE OF THE BOF BOTTOM ON LANCE LEAKAGE. THE RESULTS SHOW THAT NON-UNIFORM BOTTOM ELEVATION IS THE CAUSE OF PREMATURE LANCE LEAKAGE AND SUGGESTS SOME COUNTERMEASURE ACTIONS.
