摘要
通过试验比较了7种孕育剂的孕育效果,研究了加入量对孕育效果的影响。研究表明,复合孕育剂的孕育效果明显优于简单孕育剂,其加入量存在一最佳值。选用孕育综合效果最佳的孕育剂对所研究的灰铸铁进行处理,在保持铸铁原有特性的前提下,可使其牌号稳定在HT250以上。
Firstly the effect of seven inoculants is evaluated by experiments to select better ones. Then, the influence of quantities of three inoculants with good effect is studied to determine the favorite one. The results show that inoculants with more elements which are helpful to inoculation have better effect than the others with less and there is a optimal range of adding quantity for them in inoculation. Inoculated with inoculant Ⅵ which is the best of the seven inoculants, a gray iron with low chilling potential,low sensitivity to the thickness of castings' walls and tensile strength over 250 MPa can be produced.
