Abstract:

Vanadium is widely used in metallurgy， chemical industry and new energy industries. At present， 85% of vanadium used in the world is added to steel in the form of ferrovanadium and vanadium nitride to increase the strength， toughness and resistance of steel products. Therefore，vanadium has a huge potential in the cast wear-resistant steel material industry. From the perspective of patent analysis， the domestic patents were analyzed， the categories， legal status， application trends，technical field characteristics and applicant characteristics， etc. In this paper， in order to identify the core technology，development and application of this field of vanadium-containing cast wear-resistant steel materials is presented in China. The development trend is expected to provide valuable analysis information of our country’s vanadium-containing cast wear-resistant steel material industry， to identify future market needs， and to promote the R & D and applications of efficient utilization technology of vanadium resources in China.
