摘要
Abstract
The bucket tooth structure of large excavator was analyzed by means of the MARC/metant softs.An optimum structure design was suggested.By orthogonal experimental method,the heat treatment process of the designed low-alloyed steel was researched.The results show that there is an excellent combination properties of wear resistant steel treated after 930 ℃ quenching and 220 ℃ tempering,the hardness is 47 HRC,the low temperature impact ductility is 47 J/cm2.关键词
