TEE-SECTION Russian patent published in 1999 - IPC

FIELD: rolling; applicable in construction machine building and other types of metal structures. SUBSTANCE: tee-section has conjugation of flange and wall in its cross-section forming angle by intersection of their axes, and at least one part of conjugation line of flange and wall, and/or at least one part of line of wall, and/or at least one part of flange line, and/or at least end edge of flange, and/or edge of wall are made in the form of fragment of oblique conical section of right circular cone. In this case, profound smoothness of transition of curve parts is provided with preservation of smoothness of rolls as they wearing, reduced cost of section manufacture due to decreased volume of work involved in section rolling, and increased wear resistance of rolling rolls. EFFECT: lower cost of manufacture, higher adaptability to manufacture, reduced specific consumption of material with preserved load-carrying capacity under conditions of longitudinal compression, torsion or bending. 32 cl, 16 dwg
