Abstract

A HIGH - ADHESION / HIGH - STREBGH DEFORMED STEEL BAR, WHEREIN THE DEFORMED BAR JUST HOT - ROLLED AND HAVING SPIRAL PROTRUCTIONS OR KNOT IN ITS OUTER SURFACE FOR CONCRETE REINFORCEMENT IS REDUCED IN CROSS SECTION THROUGH A ROUNDING OPERATION AT SUCH REDUCTION RATE AS TO PERMIT THE KNOT TO REMAIN AFTER THE OPERATION, AND A PLURALITY OF FLUTES EACH OF WHICH IS OPPOSITE IN SPIRAL DIRECTION TO THE KNOT ARE FORMED IN THE DEFORMED BAR. THEN, THE THUS FORMED DEFORMED BAR IS HEAT - TREATED THROUGH QUENCHING AND TEMPERING OPERATIONS. ( FIG 1 ).
