摘要

统计分析了1Cr18Ni9Ti钢1.2 t锭电渣重熔过程母材中的Ti含量-[Ti

]

(0.586%～0.839%Ti)、渣中TiO

含量(2.1%～4.8%TiO

)和填充比(0.2～0.4)对[Ti

]

平均烧损值的影响。结果得出

电渣重熔过程电渣锭下部[Ti

]

的烧损较上部严重;随母材[Ti

]

的提高

电渣锭中平均烧损[Ti

]

降低;随渣中TiO

含量-(TiO

)提高

电渣锭下部[Ti

]

的平均烧损β值增加

而电渣锭上部β值没有明显变化

(TiO

)不宜超过2%;提高填充比有利于抑制[Ti

]

烧损。

Abstract

The effect of Ti content in steel lCrl8Ni9Ti electrode- [Ti

]

(0. 586% ~0. 839% )

TiO

content in slag- (TiO

) (2. 1% ~4. 8% ) and packed ratio (0. 2 ~0. 4) (area of electrode / area of mold) on average melting loss of [Ti

]

during 1. 2 t ESR process is counted and analyzed. It is obtained that during electroslag remelting (ESR) process the melting loss of [Ti

]

at lower part of ESR ingot is larger than that at upper part； with increasing [ Ti

]

in electrode

the average melting loss of [Ti

]

decreases； and with increasing TiO

content in slag- (TiO

)

the p value of average melting loss of [Ti

]

at lower part of ESR ingot increases

while the β value of that at upper part of ESR ingot has not obvious change

the (TiO

) larger than 2% is not available； and increasing packed ratio is available to

inhibit melting loss of [Ti

]
