A vehicle-mounted hydrogen supply method and device for hydrogen-rich smelting in a blast furnace or shaft furnace, combining steel plant hydrogen supply requirements with vehicle-mounted hydrogen supply technology used by hydrogen-powered vehicles in the field of transportation, to construct a vehicle-mounted hydrogen supply system applied to hydrogen-rich smelting in a blast furnace or shaft furnace, and providing safe and stable hydrogen-rich smelting testing and production in a blast furnace or shaft furnace smelting process, and providing an effective and reliable pathway. Compared with a newly-built hydrogen plant, the invested construction cost is low, the operation flow is simple, the method is not limited by technical upgrading and transformation, and flexibility is high. At the same time, two working long pipe vehicles and two pressure reducing system intake pipelines are used to solve the problem of continuous hydrogen supply required by blast furnace hydrogen-rich smelting. Insofar as hydrogen production technology is not yet mature, hydrogen plant construction is difficult; the use of a vehicle-mounted hydrogen supply system for hydrogen supply not only solves the problem of supplying a hydrogen source for hydrogen-rich smelting, but likewise allows for adapting to changes in rapidly developing hydrogen power technology.
