Abstract

The critical component in traditional combined drawing lines is the pulling unit, consisting consisted of a rotating cam system used to generate a reciprocating movement of two drawing carriages. The main limitation is that due to the reciprocating motion, the maximum speed of the carriages and therefore of the drawing action is limited by physics to about 120-150 m/min. Furthermore, the "handover" mechanism results in a non constant speed of the material through the drawing line, that can cause cut to length inaccuracies. Over the past 30 years Danieli has developed the fastest and most reliable drawing system based on the chain rack drawing unit that replaces the traditional cam based system. The latest chain track system consists of two caterpillar type chains that rotate at a high, constant speed- ensuring drawing speeds of up to 400 m/min for non ferrous materials and up to 180 m/min for ferrous materials. Up to 48 bars drawn bars per minute from coil can be produced.
