薄壁高强灰铸铁缸体、缸盖材质的研究

本文研究了在CE＝4．0～4．2％的高碳当量条件下，采用加入低量合金与孕育方法，获得合格的高强薄壁铸件的可能性，为工厂冲天炉熔炼生产推广应用创造了有利条件。

The paper studies the possibility of getting gualified thin wall-high strength castings in high carbon equivalent (CE=4. l～4. 2% )by low alloying and inoculant. The research result have certain important reference value for the popularization and using of the technologies of thin wall-high strength gray casting under the melting of cupola furnace in all kinds of factories.
