H-SHAPE Russian patent published in 1999 - IPC

FIELD: rolled stock production, possibly manufacture of metallic structures in building, machine engineering and other industry branches. SUBSTANCE: H-shape includes in cross section joinings of flanges and web and at least a part of joining line at least of one flange with web that form angles due to crossed axes of flanges, and web and(or) at least a part of web line and(or) at least a part at least of one flange and(or) at least one edge at least of one flange made 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 H-shape manufacture due to decreased formation degree of shape at rolling process and enhanced wear resistance of rolling rolls. EFFECT: lowered cost price of H-shape, enhanced technological effectiveness, decreased material consumption at maintaining carrying capability in condition of lengthwise axially non-symmetrical compression, torsion or bending. 32 cl, 18 dwg
