Abstract: An injection regulation and control device includes blast furnace tuyeres for introducing rich oxygen or pure oxygen to form tuyere raceways. Temperature-adjusting injection openings are evenly formed in the circumferential direction of a blast furnace and inject a hydrocarbon component-containing injection object to the blast furnace. The temperature-adjusting injection openings are located, in an axial direction, within a height range where a soft melting dripping zone is located and are not lower than the positions of the blast furnace tuyeres. The hydrocarbon component-containing injection objects are enabled to undergo a thermal cracking reaction by utilizing the temperature in the vicinity of the tuyere raceways to form a hydrocarbon thermal cracking heat absorption area. Gas products generated by the thermal cracking reaction of the hydrocarbon component-containing injection objects increase the blast furnace gas volume.

Abstract: 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 technologies to construct a vehicle-mounted hydrogen supply system applied to hydrogen-rich smelting in a blast furnace or shaft furnace, thus providing an effective and reliable pathway for safe and stable hydrogen supply in a blast furnace or shaft furnace smelting process to perform hydrogen-rich smelting testing and production. Compared with a newly-built hydrogen plant, the invested construction cost is low, the operation flow is simple, the method and device are not limited by technical upgrading and transformation, and the flexibility is high. At the same time, two working long pipe vehicles and two pressure reducing system intake pipelines are used for solving the problem of continuous hydrogen supply required for hydrogen-rich smelting in a blast furnace.
