孕育工艺具有很强的实践性,要提高孕育技术,就要根据各类铸铁的特点进行针对性的科学实践,才能获得预期的效果。一、灰铸铁的孕育灰铸铁孕育的目的是消除白口、细化石墨、增加共晶团,使铸件各部分组织、机械性能均匀,即使先后浇注的铸件在机械性能上也应保持一致,并且有良好的加工性能。笔者以为,对工厂而言,只要全力推广瞬时孕育,就能达到上述要求,并可把孕育剂的加入量节省40～80％。这是一个大胆地 Inoculation process has a strong practicality, to improve the breeding technology, it is necessary according to the characteristics of various types of cast iron targeted scientific practice, in order to obtain the desired results. First, the birth of gray iron The purpose of gray iron inoculation is to eliminate the white mouth, graphite refinement, increase the eutectic group, so that the various parts of the casting organization, mechanical properties even, even casting castings in the mechanical properties should be consistent, and Have good processing performance. I believe that, for the factory, as long as the full promotion of instant inoculation, can meet the above requirements, and the addition of inoculant can save 40 to 80%. This is a bold
