摘要
分析了３Ｃｒ２Ｗ８Ｖ钢模锻顶头的现状。介绍了铸造内外水冷穿孔顶头的材质、结构形式和生产工艺流程，对模锻法和铸造法生产顶头的制造成本进行了对比。使用表明，铸造内外水冷穿孔顶头的成本低，使用寿命长，生产工艺易掌握，值得推广应用。
The author provides an investigation of the currently used die-forged piercing plug made of 3Cr2W8V Steel and an introduction about the cast externally/internally water-cooled piercing plug involving such main aspects as material,structure and manufacture process flow.Compared with the die-forging process,the casting process is more cost effective.And so far as the said cast plug is concerned,relevant operational practice has proven that this kind of plug is in possession of advantages namely,lower cost,longer service life and being easy to make.It is worth spreading.
