本文分析了小方坯连铸提高拉速后出现的铸坯低倍组织缺陷,就其表现形式进行了统计分析和讨论,并且采取了相应的具体工艺改进措施,使高拉速方坯低倍缺陷大幅度降低。 In this paper, we analyze the microstructure defects of cast billet after the continuous casting of the billet increases the casting speed, and make a statistical analysis and discussion on its manifestations, and take the corresponding specific technological improvement measures to make the high-speed billet low times Defects greatly reduced.
