There is the speed change system requirement determining to change ratio, for each change of the final diameter of wire rod, corresponding change must be made to the intake section of the ring of all rolling machine frames of milling train and calibration process part, namely must replace all rolling rings.
This needs time more or less changes the cylinder in rolling machine frame, and during this period, whole rolling equipment is out of service.
When the speed change system of these fixed ratios, the diameter of the rolling ring of the groove of series must be only different with little value each other subsequently, are about +/-0.5mm, otherwise the longitudinal tension force on rolled wire rod, namely draw, can not be controlled, and therefore cause rolled products out-of-size.
It is impossible for carrying out adjustment to the area reduction ratio of the wire rod for each milling step, because this will mean, use the finishing mill or rod-rolling mill that are provided with different suitably selected transformation ratios in the prior art devices, such as, by means of so-called " change-speed gearing ".Prior art has attempted to propose the multiple solutions to this problem.File US7523632 describes the milling train with 1 or 2 motor, and this 1 or 2 motors have the variable ratio by means of mechanical speed change.
Consider the kind of the intensely processed products must produced by wire rod rolling equipment, such solution causes some the complicated restrictions about the mechanical driving device be arranged on rod-rolling mill.These transmission devices must have the ratio of tens, and very expensive and heavy.
