ROLL-FORMED NOTCHED THROUGH ANGLE Russian patent published in 1999 - IPC

Abstract RU 2134224 C1

FIELD: metal rolling; production of cold-rolled sections for packing coiled steel. SUBSTANCE: roll-formed angle has webs one of which is bent to arc of preset radius for forming cylindrical surface. Second web is provided with variable-height cross corrugations with maximum size on web edge and minimum size at opposite side. Bent web has arc notches of height h found from formula: h=(0.94-1.06) (R/S²)^0,155+S where R is radius of cylindrical surface and S is angle thickness. EFFECT: enhanced characteristics of angle for packing coiled steel. 3 dwg, 1 ex
