ROLLING METHOD OF CHANNELS Russian patent published in 2009 - IPC B21B1/08

Abstract RU 2356656 C1

FIELD: metallurgy.

SUBSTANCE: method includes successive clamping of work material in gauges. Stable height of shelves and qualitative edge machining of shelves along the full length of rolled channel is provided ensured by blank after rough group of gauges is rolled with constant width of wall and constant height of profile between control gauges, herewith shelf height changing Δh in control gages of finishing group is regulated by mathematical dependence.

EFFECT: reduction of discard, subquality products and improvement of marketable appearance of products, and also production increasing ensured by reduction of adjusting time.
