METHOD OF OBTAINING SHAPED MATERIAL OR ROD AT NORMAL TEMPERATURE AND SHAPED MATERIAL OR ROD OBTAINED

摘要

PURPOSE: To make it possible to obtain a multiple-section element including plural sections or bars or both (hereafter simply described as the sections or bars) finished from hot rolled products and to divided the various sections or bars simultaneously at a time in a cold state without interrupting continuous production. CONSTITUTION: This method simultaneously obtains the plural sections or bars 14 in the cold stage by starting from the hot rolled single multiple-section element 10 which includes the plural sections or bars 14 being the sections or bars 14 having symmetrical, asymmetrical or special cross sections and relating to the representative dimensions of a specific rolling mill and may have one section or bar 14 and a web between another one section or bar, then cooling the single section element. The hot rolled single multiple-section element 10 is cooled in a line in series to the rolling mill and is then subjected to the operation to simultaneously and longitudinally divide the element in the cold state without breaking the continuity of the work in order to separate the individual small sections or bars 14.
