攀钢集团成都钢铁公司采用92 t偏心底(EBT)电弧炉-92t钢包炉生产成分(%):0.32~0.38C
1.25~1.55Mn J55管坯钢。电弧炉出钢时[C]≥0.10%
[P]≤0.015%;EBT出钢约1/4时
加入硅铝钡脱氧剂200kg/炉
通过控制LF精炼时渣中FeO浓度小于0.5%
可使钢中S含量低于0.015%。在LF处理时
通过喂Al线吹氩8~15 min后再喂0.4~0.6kg/t CaSi线处理
以促进夹杂物上浮
防止中间包水口堵塞。
The tube bloom steel J55-0.32~0.38C
1.25~1.55Mn is produced by 92 t EBT are fumace-92 t ladle furnace(LF)at Chengdu lron and Steel
Pangang Group. With controlling [C]≥0. 10%
[P] ≤ 0.015 at arc furace tap- ping
adding silicon- aluminium- barium deoxidant 200 kg/heat at EBT tapping a quarter of metal to decrease the oxygen content in molten steel
and with controlling FeO content in slag during LF refining
the sulfur content in steel shall be lower than 0.015%.During LF refining with feeding Al wire
argon stiring for 15 min than feeding 0.4~0.6 Kg/t CaSi wire to promote inclusion floating off
the nozzle clogging could be prevented.
