Abstract:

Abstract: Through analyzing and comparing the composition and performance index of several kinds of mining excavator structure material, the article presents that materials of mining excavator should meet the "because of the operation minimum temperature region is different, there must be sufficient low-temperature impact toughness" requirements, in addition to need to meet the necessary conditions of strength and stiffness.
