Study on the reduction efficiency of soft reduction on continuous casting bloom

Abstract

This paper explores factors influencing the reduction efficiency of bloom during soft reduction. The research results show that the center solid fraction affects greatly on the reduction efficiency of bloom, while the reduction amount, the width and the thickness of casting strand and the diameter of roller have little effect. The results from the comparison of the crown rollers and normal rollers show that the reduction efficiency of normal roller is larger than that of crown roller with 1 mm of reduction amount, while when the reduction amount is 5−15 mm, the reduction efficiency of normal roller is smaller than that of crown roller. However, the load borne by crown roller is much smaller than that of normal roller.
