Abstract
FOR THE DEVELOPMENT OF THE WORK, DATA WERE COLLECTED FROM INDUSTRIAL ROLLING MILLS AT COMPANHIA SIDERúRGICA NACIONAL (CSN) IN ORDER TO COLLECT PROCESSING PARAMETERS. IN THE PRESENT WORK, THE EFFECTS OF ROLLING WITH DUMMY PASS ON ROUGHING IN NB MICROALLOYED STEEL, FOR THIS, DATA FROM USUAL PROCESSING WITH DIFFERENT NUMBERS OF PASSES AND PROCESSING WITH A DUMMY PASS WERE CONSIDERED TO ANALYZE THE INFLUENCES OF THESE CONFIGURATIONS ON THE REDUCTION PROFILES AND NIOBIUM PRECIPITATION. THE RESULTS POINTED TO A SIGNIFICANT IMPACT ON THE PERCENTAGE REDUCTION AND INCREASE IN LAMINATION LOAD FOR LAMINATIONS WITH A DUMMY PASS. THE SIMULATIONS INDICATED SIMILAR BEHAVIOR BETWEEN THE NIOBIUM PRECIPITATION OF THE STANDARD ROLLING AND DUMMY CASES
