灰铸铁复合孕育强化生产的试验研究

对优化的复合孕育剂在生产条件下进行了粒度直径、孕育处理温度及加入方式等孕育处理工艺因素的研究,同时检测了经孕育处理的铁液的抗衰退能力、流动性、体收缩等铸造工艺性能,另外还进行了抗拉强度、白口倾向、断面敏感性、硬度、加工性能及弹性模量等力学性能及使用性能的测试研究,验证了复合孕育剂有良好的孕育强化效果.

Research on Strengthen of Grey Iron Compound Inoculation in Production Practice

Synthesized study have been made for the inoculation process which include size of the agent, adding temperature and adding methods of the optimization compound inoculation of grey iron. Feature of casting process related to which involved in fade of the function, fluidity and contraction has been tested. And the mechanical properties and character of the inoculation products which are about the tensile strength, the chill tendency, the sensitive of section, the hardness, the forming property and the modulus of elasticity have been measured and the function of the compound inoculation agent is effective.
