摘要
研究了SG变质剂对可锻铸铁石墨化退火的影响。试验表明,SG可使第一阶段石墨化退火时间缩短到1.5小时之内;等二阶段退火时间缩短到2.5～5.5小时;低温(850℃)下进行第一阶段退火,石墨化时间在正常时间范围之内。
The influence of SG inoculant on graphitizing annealing of malleable cast iron was investigated. The results showed that SG inoculant could shorten the first stage graphitizing annealing time to less than 1.5h, and shorten the second stage annealing time to 2.5-5.5h.Under the 850℃the first stag eannealing time could be kept within normal annealing time.
