摘　　要：探讨了35MnBM钢带状组织的形成、危害及消除方法。通过采用热送热装工艺试验,提高连铸坯的装炉温度,延长钢坯在炉内的高温扩散时间,使35MnBM钢坯的带状组织级别全部控制到2.5级以下,满足了用户对带状组织的控制要求。It is discussed the forming, damage and eliminating method of banded structure in 35MnBM steel. Hot delivery and hot charge process is tested to increase the charging temperature of continuous casting billet and prolong the high - temperature diffusion time of billet in furnace, and so the banded structure level can be all controlled below 2.5, and meet the requirement of customer.
