Abstract

Method for production of ribbed reinforcing steel, a steel wire being produced by hot rolling and, in the process, provided with oblique ribs and, if required, longitudinal ribs (in particular according to DIN 488). The steel wire (5) hot-ribbed in this way is subjected to cold stretching and its yield strength and elongation are thereby adjusted. The steel wire (5) is stretched continuously and, for this purpose, is guided over at least two driven stretching pulleys (1, 2) (or stretching rolls) working at different peripheral speeds on the steel wire (5). The degree of stretching is controlled via the difference in the peripheral speed of the two stretching pulleys (1, 2). The yield strength and elongation are controlled via the stretching rate. The invention also discloses an arrangement for carrying out the method. <IMAGE>
