| Abstract: | The influences of furnace charges, chemical composition, quality of vermicularizing alloy, holding duration after vermicularizing treatment and tapping temperature on percentage of vermicular graphite were discussed. How to control and check percentage of vermicular graphite was descrihed, and some suggestions to prevent vermicularizing effect degeneration were offered. Practice has showed that the v.g. percentage could be kept in the range of 55%-85%. |
