摘要： 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.
摘要翻译： 本发明的实施例包括从钢水中形成坯料并热轧坯料以减小坯料的横截面积。 此后，坯料被热轧成具有横截面积的引导通道，引导通道包括邻近杆的中心纵向轴线的减小的宽度尺寸。 在本发明的一个实施例中，坯料可以通过将坯料送入第一组辊而形成具有沙漏或花生形状的横截面积的引导条。 在形成导线棒之后，它通过第二组辊，以形成没有纵向肋的基本上连续的螺纹钢筋。 导线棒的横截面积有助于使用标准钢筋制造工具和设备来生产基本上连续的螺纹钢筋产品，而不使用纵向肋。
