摘要
复合孕育金属型可锻铸铁的退火工艺与普通孕育金属型可锻铸铁的相比，第一阶段石墨化退火时间由４５ｍｉｎ减少至２５ｍｉｎ；第二阶段石墨化退火时间由５ｈ５０ｍｉｎ缩短至１ｈ２０ｍｉｎ．
The annealing process of multiple inoculations metal-mould malleable cast iron is compared with common inoculation one,the first stage graphitization annealing time is decreased from 45 minutes to 25 minutes,and the second stage graphitization annealing time is shortened from 350 minutes to 80 minutes.
