Study on Cored-Wire Injection Vermicularizing Process for Vermicular Graphite Cast Iron Production
The feasibility of the cored-wire injection vermicularizing process for vermicular cast iron production was studied in this paper. The influences of composition of cored-wire and its addition amount on the percentage of vermicular graphite were analyzed, and the parameters of cored-wire injection vermicularizing process were determined by carrying out vermicularizing treatment experiments. Comparing it with pour-over process showed the superiority of the cored-wire injection process in the stable vermicularizing treatment. The results showed that the cored-wire injection vermicularizing process for vermicular cast iron production was feasible and excellent and stable vermicularizing effect could be obtained by using cored-wire injection vermicularizing process.
