硅钡孕育剂在缸体铸件上的应用研究

摘要

The influence on material properties and microstucture of cylinder body castings with silicon barium inoeulant and ferrosilicon inoculants being used has been studied, resulting in that the requirements for the mechanics properties and the microstucture of castings have been ensured with reduced casting production cost, after using silicon barium compound inoculation process instead of copper alloying technology.%本文研究了使用硅钡孕育剂和硅铁孕育剂对缸体铸件材质性能和组织的影响.实验结果表明,使用硅钡孕育剂复合孕育工艺替代铜合金化工艺后,不但可以保证铸件本体的机械性能和组织要求,而且降低了铸件生产成本.
