  • Patent number: 9855594
    Abstract: Embodiments of the invention comprise forming a billet from molten steel and hot rolling the billet to reduce the cross sectional area of the billet. Thereafter, the billet is hot rolled into a lead pass bar having a cross-sectional area comprising a reduced width dimension located adjacent to the center longitudinal axis of the bar. In one embodiment of the invention, the billet can be formed into a lead pass bar having a cross-sectional area in the shape of an hourglass or peanut by feeding the billet through a first set of rolls. After the lead pass bar is formed, it is passed through a second set of rolls in order to form the substantially continuous threaded rebar without longitudinal ribs. The cross-sectional area of the lead pass bar helps to produce a substantially continuous threaded rebar product without longitudinal ribs using standard rebar manufacturing tooling and equipment.
