This problem could be solved by using ferrite nodulargraphitecastiron.
采用以铁素体为基的蠕墨铸铁可解决此问题。
2
The domestic and foreign nodulargraphitecastiron standard samples were analyzed with vacuum direct-reading spectrometer and were applied in the routine analysis.
运用真空直读光谱仪分析国产和国外产球墨铸铁标样,并应用在生产实践、炉前分析中;
3
It is a basic demand for evaluating the microstructure and performance to determine the graphite size and its spheroidization rate in nodularcastiron.
