User report on tungsten carbide tamping tools
The tungsten carbide tamping tools have been applied in our track maintenance division since 2016. The monoblock forging of the tamping tools with super resilience and strength and the all-brazed tungsten carbide on the five facets of tamping tool spade with HRA 87.5 hardness enable the very good wear resistance and impact strength of the tamping tools; the relatively slim design of the tamping tool spade mitigates the insertion resistance, which helps prolong the life service of the tamping tools. According to the data statistics in our tracking for the application of the tamping tools on Beijing-Taiyuan, Beijing-Tongpu railway lines, etc, the average performance of the tamping machines reached 400,000 times, equal to 500km and the performance of the tamping tools is almost comparable to that of the ones manufactured by western counterparts. The below is the data collection:
