研究了用 Bi 系和 Te 系复合孕育剂孕育处理及锌气氛退火对铁素体可锻铸铁退火过程石墨化的综合影响,结果表明,复合孕育和锌气氛退火是缩短铁素体可锻铸铁退火周期的有效措施。
The combined effect of Bi-and Te-based inoculant inoculation and zinc atmosphere annealing on the graphitization of ferrite malleable iron during annealing was studied. The results show that compound inoculation and zinc-atmosphere annealing are effective measures to shorten the annealing period of ferrite malleable iron .
