转炉炉下钢包车轨道分析与改进

Analysis and Improvement of Ladle Car Track Under Coverter

转炉炉下轨道主要供钢包车和运渣车行驶。某钢厂转炉钢包车轨道型号为QU120,轨道通过U型地脚螺栓与基础连接。自2012年投入运行以来,转炉钢包车轨道在使用过程中频繁出现横向断裂、纵向断裂和轨面延展,对生产冲击比较大。通过对现有轨道进行分析,提出改进方案。在实际使用中,改进后的轨道未出现断裂和压溃延展的现象。

Ladle track under coverter is mainly used for buggy ladle and slag truck driving. The ladle track type is QU120 and connected to foundation with U-type anchor bolt. The coverter ladle track appear transverse crack, longitudinal crack and extension of the track face frequently from 2012 year. This wreck produce a large impact on production. Put forward the improvement scheme based on existing track analysis. In actual use, the improved rail was no fracture and collapse extension phenomenon.
