ANGLE SHAPE Russian patent published in 1999 - IPC

FIELD: rolled stock production, possibly metallic structures in building, machine engineering and other industry branches. SUBSTANCE: angle shape includes in cross section flange joining and at least a part of inner line of flange joining that form angle at crossing their axes and(or) at least a part of inner line at least of one flange and(or) at least a part of outer line at least of one flange and(or) edge at least of one flange and(or) shape apex in the form of fragment of oblique cone section of straight round cone. It provides increased smoothness of transitions of curve portions at maintaining smoothness independently upon roll wear, lowered cost price of shape due to decreased formation degree of shape at rolling process, increased wear resistance of rolling rolls. EFFECT: lowered cost price of angle shape, enhanced technological effectiveness, decreased material consumption at maintaining carrying capability in conditions of lengthwise compression, torsion or bending due to rational distribution of metal along cross section of shape. 25 cl, 20 dwg
