2.5吨汽锤操纵杠杆断裂原因的研究

The Cause for The Cracking of Operating Leverin a 2.5Ton Steam Hammer

通过宏观观察、微观分析、力学性能测定及金相组织鉴别等,确定2.5吨汽锤操纵杠杆的断裂是构件设计错误加上焊接工艺不当所致。

By means of macroscopic observation, microscopic analysis, mechanical property determination and metallographic structure discrimination, it is concludsd that the fracture of operating leaver of 2.5t steam hammer results from the components dssign mistake plus bad welding process.
