提高压铸冲头使用寿命的试验研究

The Experimental Study of Die Casting Plunger for Increasing the Servce Life

从冲头磨损的机理分析入手,采用45号中碳钢,经渗硼处理,提高表面硬度和韧性,可使其使用寿命在原来的基础上提高6～10倍。

The operating life of plunger are a common problems in die casting process, In this paper, through the theoretic analysis, replace the spheroidal cast iron by medium carbon steel. The life of plunger be increased six times to ten times than the original state. The economical benifit and societal efficiency are goodly.
