The influence of SG inoculant on graphitizing annealing of malleable cast iron was investigated.
研究了SG变质剂对可锻铸铁石墨化退火的影响。
2
The graphite annealing, can get malleable iron, processing is convenient.
经石墨化退火后,即可得到可锻铸铁,加工方便。
3
The heat treating process was improved for the malleable cast iron, in accordance with its long annealing period, coarse graphite, residual carbide, lower mechanical properties and limited serve life.
