Abstract

With using the process measures including modifying the low basicity (2. 6) CaO-Al

-SiO

slag series to high basicity ( ≥5. 0) CaO-Al

-SiO

-CaF

slag series

increasing the [Als

]

in steel before LF refining from 0. 02% ~ 0. 03% to M 0. 06%

improving the atmosphere casting to box type Ar shielding casting and improving the 3t ingot body casting time from 6 ~8 min to 4 ~5 min

the [O

]

and [S

]

in cold-working die steel Cr12MoV are respectively [O

]

≤ 18 X 10

-6

and [S

]

≤ 0. 005%

and the comprehensive products yield increases from 74. 35% to 80. 12%.
