一种灰铸铁孕育剂的制备方法及其应用
摘要：
本发明公开了一种灰铸铁孕育剂的制备方法，包括以下步骤：将66～70％的Si，1～3％的Zr，1～2％的Ca，0～2.5％的Mn，Fe3O4：0.5～1.5％以及余量为Fe以及不可避免的微量元素混合均匀、粉碎、熔炼、搅拌、冷却、粉碎，备用。本发明还公开了该灰铸铁孕育剂的应用。采用本发明提供的灰铸铁孕育剂，能够改善灰铸铁的综合性能，并提高孕育效率。
摘要（英）：

The invention discloses a preparation method of a gray pig iron nucleating agent. The preparation method comprises the following steps that 66%-70% of Si, 1%-13% of Zr, 1%-2% of Ca, 0-2.5% of Mn, 0.5%-1.5% of Fe3O4 and the balance Fe and inevitable trace elements are evenly mixed, smashed, smelted, stirred, cooled and smashed for use. The invention further discloses application of the gray pig iron nucleating agent. According to the gray pig iron nucleating agent, the comprehensive performance of gray pig iron can be improved, and nucleating efficiency is improved.
