MANUFACTURING METHOD OF COLD-ROLLED TITANIUM-BEARING STEEL Russian patent published in 2009 - IPC C21D8/04 C21D9/48 

Abstract RU 2356948 C1

FIELD: metallurgy, processes.

SUBSTANCE: invention relates to rolling mill, particularly to production methods of sheet steel. For increasing of sheet steel consumer properties ensured by improvement of its formability sheet is subject to recrystallisation annealing and temper rolling, additionally this annealing is implemented in bell furnace with protective hydrogenous atmosphere and with isolation during seven hours at temperature 250…350°C, and temper rolling is implemented with reduction of cross-sectional area εΣ which is the same for all thickness of sheet and equal to 1.1±0.1%.

EFFECT: new manufacturing method of cold-rolled titanium-bearing steel.
