Abstract

Las modalidades de la invención comprenden formar un tocho de acero fundido y laminar en caliente el tocho para reducir el área de sección transversal del tocho. Después, el tocho se lamina en caliente en una barra de paso principal que tiene un área de sección transversal que comprende una dimensión de ancho reducida ubicada adyacente al eje longitudinal central de la barra. En una modalidad de la invención, el tocho se puede formar en una barra de paso principal que tiene un área de sección transversal en la forma de reloj de arena o cacahuate al alimentar el tocho a través de un primer conjunto de rodillos. Después de que se forma la barra de paso principal, se pasa a través de un segundo conjunto de rodillos con el fin de formar la barra de refuerzo roscada sustancialmente continua sin nervios longitudinales. El área de sección transversal de la barra el paso principal ayuda a producir un producto de barra de refuerzo roscada sustancialmente continua sin nervios longitudinales utilizando herramienta y equipo de fabricación de barras de refuerzo estándar.
