Abstract This article introduced the basic design ideas of steel 45# about dynamic soft reduction model parameters for No.2 Bloom-caster of Pansteel as well as the selection of the related model parameters. Steel 45# production practice shows that after the implementation of dynamic soft reduction, central porosity ratio≤0.5 increased from 88.48% to 100%, central bloom without shrinkage ratio increased from 79.72% to 98.74%, central segregation index of carbon improved from 0.88~1.11 to 0.92~1.06, the internal quality of steel 45# improved significantly.
