HOT ROLLED WIDE STRIP STEEL Russian patent published in 2009 - IPC B21B1/26 

Abstract RU 2344008 C1

FIELD: metallurgy.

SUBSTANCE: prevention of "fracture" defect on cold-rolled strips is achieved owing to limit deviations of strip thickness at h=1.8...6.0 mm not exceeding Δh=±(0.0245h+0.053) mm, also cross section of a hot rolled strip has a lenticular shape with a prominence δ=0.04...0.08 mm at strip width B=1.0...1.25 m and height h≤3 mm and with prominence δ=0.04...0.10 mm at bigger width and thickness, wedging of section not more, than 0.04 mm.

EFFECT: upgraded quality of wide strip (sheet) steel and band produced with following cold rolling.
