起重机车轮性能研究

Study on Performance of Crane Wheels

本文介绍一种材质是45钢,通过锻造-辗压工艺制造的起重机车轮,主要对这种工艺制造的起重机车轮的元素含量、硬度、金相组织进行检测,结合《起重机车轮》(JB/T 6392—2008)中对起重机车轮的力学性能、热处理、成品车轮的质量要求,对车轮性能进行分析。

This paper introduced a kind of crane wheel made of 45 steel by forging-rolling process. It mainly inspect- ed the element content, hardness and metallographic structure of the crane wheel made by this process. Combining with the mechanical properties, heat treatment and quality requirements of crane wheels in Crane Wheels（JB/T 6392-2008）, the performance of the wheel was analyzed.
