| Abstract: | The reasons causing surface scab and graphite holes of a heavy section working table casting were analyzed,and proper measures were adopted:using filter to skim slag;keeping enough time intervals between molding,coating brushing and pouring;controlling coating preparation and brushing operation,adjusting C and Si content of the iron melt,as well as using chills.As a result,the quality of castings have met technical requirements. |
