ABSTRACT:
A casting powder to be used for ingot casting and continuous casting of steel which contains substantially no carbon particles.
It contains, instead of carbon particles, BN or other nitrides as an agent for adjusting fusion rate of the casting powder so as to fully prevent carburization and carbon pick-up caused by the carbon particles which has heretofore been added to the powder for control of the fusion rate. This new casting powder may contain a reducing agent in addition to the nitride.
