By impr vement f the temper ature h ld c nditi ns at the steel la- dle and tundish and by selecti n f the ptimal temperature m de in LF fur nace, a c n- sistent and l w verheat result can be achieved in the pr cess f casting the high carb n steel at l w speed and theref r e the carb n segregati n in the slab can be effectively r e- duced.
