铁水包空包保温对钢铁企业节能减排和降低成本具有重要意义。对加盖和不加盖的铁水包空包在5 h内的温降过程进行了现场测温,结果表明,铁水包加盖对铁水包空包,特别是中上部包衬具有显著的保温作用。铁水包加盖保温应在转炉兑铁结束后尽早进行,同时缩短空包时间,以取得最佳的保温效果。 Hot metal package empty package insulation for iron and steel enterprises energy saving and reduce costs is of great significance. Field temperature measurement of the temperature drop during 5 h with and without capping of the empty ladle showed that the hot ladle capping had a significant heat preservation effect on the empty ladle, especially in the upper ladle . Hot metal ladle lid insulation should be carried out as soon as possible after the converter against iron, while shortening the empty package time, in order to obtain the best insulation effect.
