STEEL STRIP MANUFACTURING DEVICE Russian patent published in 2018 - IPC C21D9/56 C23C2/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to the manufacturing devices, made with the possibility of the coated steel strip manufacturing, applied by immersion into the melt, and the cold-rolled steel strip. Steel strip 1 manufacturing device comprises continuous annealing furnace 2, connected to the continuous annealing furnace 2 nose 6, sealing device 10 with contact-type plates and sealing device 20 with the non-contact type rollers, which are located on the nose 6 entrance side in the steel strip S movement direction in this order, tank 5 for the coating application by immersion in the hot melt, which can move; and the immersion roller 31 intended to change the steel strip S path direction after its passing through the nose 6. Steel strip manufacturing unit by the coating application by immersion into the hot melt, intended for the steel strip manufacturing by the coating application by immersion into the hot melt due to the continuously annealed steel strip S movement in the continuous annealing furnace 2 to the hot melt dip coating tank 5. Cold-rolled strip manufacturing unit, intended for the cold-rolled strip manufacturing by the continuously annealed steel strip movement in the continuous annealing furnace 2, without the need for the steel strip passing through the hot melt dip coating tank 5, configured to replace each other.

EFFECT: technical result consists in the atmospheric air from the furnace to the outside outflow prevention and the atmospheric air entry into the furnace prevention.
