莱钢特钢厂用50 t电弧炉-LF(VD)工艺生产40MnB钢。结果表明
通过保持LF精炼渣的渣碱度3.0~5.5
喂Al线
并在LF精炼末期喂硅钙线
扒渣后50 Pa VD处理35~40 min
VD后喂Al线
再喂钛线
用铝皮包裹FeB

The steel 40MnB is produced by 50t EAF-LF(VD) process at Special Steel Plant
Laiwu Steel.Results showed that with insuring refining slag basicity 3.0~5.5
feeding Al wire
then feeding silicon-calcium wire in LF refining end phase
skimming and 50 Pa VD treated for 35~40 min
after VD feeding Al wire and titanium wire
and inserting ferroboron FeB
-A cladding of aluminium sheet into liquid steel and soft argon blowing
the yield of boron of ferroboron was 65%~75%
boron content in steel was 0.0018%~0.0025%
and oxygen content and nitrogen content in steel were respectively ≤20×10
and ≤80×10
