7、>0.250~0.400硫[S]特类≤0.020一类>0.020~0.030二类>0.030~0.050三类>0.050~0.070铁水温度≥1280℃带渣量≤1％注：①正常情况下转炉炼钢用铁水应符合以上要求，考虑转炉炼钢对铁水的适用情况，以上条件可暂不作为验收依据；但当铁水硅(%)>0.85、锰（％）>1.00、磷（％）>0.100、硫（％）>0.070，铁水温度(℃)<1280，应及时通知铁厂高炉，以便作出调整。③优先使用L04、L08牌号铁水，锰含量三组、磷含量二级以下、硫含量出格铁水应尽量少用。1.2当铁水罐到炉前时，应查明铁水罐号和对应（高炉

8、）炉号，确认该罐号铁水成份已传送至转炉主控室；并按要求做好铁水成分记录；1.3兑铁前，具备条件
