ingredient and structure of final slag and slag skin during electroslag remelting (ESR) process of 7. 6 t ingot of steel MC5 with 310 kg ANF-6 slag (/% :69.14CaF

) are analyzed and examined. Results show that after ESR the CaF

and Al

O
3
content in final slag decrease obviously and the CaO and SiO
2
content increase markedly; the ESR slag skin is divided into three layer from outside to inside of skin
that are the outside-rapid cooling layer
the middle-selective recrystallization layer
in this layer the Al

O

content is obviously higher than that original value
and the inside thi
rd layer-eutectic layer; the average ingredient content in different height has obvious difference
in it the Al

O

content in median part is obvious higher than original value.
