摘要 |
In continuously casting steel, at least two pairs of reduction rolls are arranged near the crater top where the solidification of the molten steel in the cast strand is completed, said reduction rolls having a roll pitch of 200 to 420mm and giving a draft per pair of 0.1 to 2.0%, and said cast strand is reduced near the to of said crater, whereby the inner quality of said cast strand is remarkably improved.
