SYSTEM FOR SUPPLYING AUXILIARY RAW MATERIALS FOR CHARGE MATERIAL HOPPER OF BLAST FURNACE AND METHOD OF APPLYING THIS SYSTEM Russian patent published in 2024 - IPC C21B7/20 

FIELD: metallurgy.

SUBSTANCE: group of inventions relates to a system for supplying auxiliary raw materials to a blast furnace charge material hopper and a method for supplying auxiliary raw materials to a blast furnace charge material hopper in which this system is used. The system includes hopper (1) for auxiliary raw materials, feeders (2), tray (3), vibrating screen (4), and weighing funnel (5) connected in series. Hopper (1) is equipped with charge hoppers (6) and feeders (2), which are placed corresponding to charge hoppers (6), and charge hoppers (6) communicate with tray (3) through the corresponding feeders (2). Hopper (1) includes body (7) and dividing partitions (8), inlet hole (9) for the material is provided on one side of body (7), outlet hole (10) for the material is provided on the other side of body (7) of the material hopper opposite the material inlet (9). Dividing partitions (8) are sequentially placed along the longitudinal direction of material inlet (9) and divide body (7) into charge hoppers (6) communicating with material inlet (9) and material outlet (10). The volumes of the corresponding charge hopers (6) are not equal.

EFFECT: design of the hopper body is optimized, the number of vibrating screens is reduced, and the load factor of the vibrating screens is increased.
