Abstract

Procedimiento de laminación de perfiles angulares de acero, principalmente de angulares, caracterizado porque prevé formar en una primera pasada sobre al menos, una cara de una preforma con cuatro caras planas, al menos una protuberancia de superficie redondeada, reduciendo simultáneamente en un tercio, aproximadamente, el grosor inicial de la preforma, transformar en una segunda pasada el contorno de este protuberancia en un contorno triangular, reduciendo simultáneamente de nuevo, en un tercio aproximadamente, el grosor de la preformar, redondear en una tercera pasada los ángulos inferiores de los extremos de la preforma, y plegar , en una pasada final, las alas que se extienden a ambos lados de la protuberancia triangular, en ángulo recto.
