A set of domestic dynamic soft reduction equipment was installed at No5 280 mm x 380 mm bloom concast- ing line at Baotou Steel
bv which the pilot production for heavy steels U71 Mn and U75 V has been carried out for more than one vear. Results showed that with suitable process conditions
the central carbon segregation in heavy rail steels improved obviously by using soft reduction technology: the index of central carbon segregation in cross section of bloom was ≤1.08
the fluctuation of index of carbon segregation along longitudinal central line of bloom appreciably decreased and the chenii- cal composition deviation of steel rail also decreased.
