Title of the invention

Method and device for deflecting rod-shaped material

Field of application of the invention

The invention relates to a method and a device for deflecting rod-shaped material, for example, the separated out of a running rolling stock specimen within the finishing of a rolling mill.

Characteristic of the known technical solutions

In wire and fine steel rolling mills, the rolling stock exits from the last stand with a high final rolling speed and arrives via a roller table to the following equipment: warm shears, cooling sections, braking devices

the cooling bed. % , /

  According to the technological invention, there is a need to redirect the rolling stock on the conveyor to the last rolling stand down to the cooling bed at the various stages or that a test piece separated from the rolling stock must be guided out of the rolling line.

Known devices for deflecting the rod tips, ends of the head, remaining lengths or for sample removal have as V / oak a controllable in the way of the rolled baffle flap, which can be swung out of the bottom of the rolling stock guide and deflects a roll bar down or out of the 'alzlinie. Also, for deflecting rolled bars from the rolling line in a horizontal plane pivotable \ I am known. (DE-GLI 1,962,350, 49c, 13/01;

15-> O 4.1

These switches are controlled manually. They are therefore only in the range, such rolling speeds used that the responsiveness of the operator not

• 5 overwhelm. In the range of high rolling speeds, in particular for deriving a sample rod separated from the running rolling rod, a hand-controlled switch is therefore not suitable. By direct contact of the rolling stock with the deflector flap, high rolling speeds would lead to breakage of the rolling stock and thus an accident cause.

Thus, another solution is known (DE-OS 1 752 483, B 23 d, 33) »by directly behind the scissors with the scissors drive geared detachable disc drum is arranged. In the direction of passage of the rolling stock a plurality of passages are provided for the rolling stock at the periphery of the disk drum. The bottom of each located in the rolling line implementation is equal to the request level of Scherenrollganges. The lamellar drum, designed in the manner of a

: 0 Vielnutwelle is coupled by turning on the test section causing the control member by an intermediate coupling at a standstill with the scissors drive.

, By lying on the control line of the sample section in the rolling line implementation of the disk drum, the sample length of the preceding rolling stock and also the test bar is guided while the disk drum rotates. As a result, the test bar is deflected out of the rolling line while it is running into the passage of the lamella drum. Following the rehearsal even Walzgutspitze already runs in the first-mentioned implementation of the lamella drum adjacent implementation, which rotates during the period of the trial run in the rolling stock line. The sample rod running in front of the rolling stock still runs, in a lying in the rolling line groove of the lamella drum fixed guide while running in the same implementation sample already slides in the direction of rotation of the lamellar drum offset from the rolling line arranged channel of a fixed guide and thus the rolling stock line is transported.

However, this solution involves the risk that when deflecting the risk of damage, at the moment where the lamellae drum pushes the end of the rolling stock from the rolling line to clear the way for the sample bar. Apart from the fact that this solution is very material-intensive, the system must by. Clutch and gear to respond slowly to the control pulses, so that one has to come to the conclusion that this solution can not work reliably at high rolling speeds.

In Ablenkvorgängen done by mechanical means, there is always the disadvantage of direct contact of the rolling stock with the deflection, so these solutions are only useful at low rolling speeds.

Object of the invention

The aim of the invention is the safe deflection of rolling stock from the rolling line, whereby the possibility of an accident does not exist, in order to increase the throughput in the finishing area.

Explanation of the essence of the invention

The object of the invention is to enable a non-contact deflection of rolling stock at high speeds from the rolling line.

According to the invention, the object is achieved in that a force is exerted on the rolling rod in the region of the deflection to be effected by means of an external magnetic field surrounding the Y-axis and a current flowing through the rolling rod. In rolling line behind the scissors, a roller system covering magnet system is arranged, whose poles

i are arranged so that the direction of the magnetic FeI-perpendicular to the deflection and perpendicular to the direction of movement of the rolling stock. Before and behind the magnetic poles electrical contact elements are arranged in a roller table. In the rolling direction behind the last contact element is the roller table branch, the lower pole, on which slides the stock to be deflected, is preferably

provided with a wear layer. The deflection process is performed on the basis of the. By a current flow through an electrical conductor in a magnetic field caused force perpendicular to the magnetic field direction and perpendicular

) 5 acts to the direction of movement. The deflection process can be triggered by switching on the magnetic field in the presence of current flow through the whale itself or switching on the current flow in the presence of magnetic field. The triggering of the deflection process can be done for example by a light barrier behind the last contact element. In order to obtain the smallest possible Able.nkzeiten, which are necessary at high rolling speeds, the magnetic field can preferably be constructed by, a capacitor discharge.

Embodiment . .. '\

Below, the invention will be explained with reference to an embodiment. Show it:

Fig. 1 roller table with deflector and roller table branch Fig. 2 section through a deflection magnet

According to Fig. 1, the rolling stock 1 passes through the formed as a contact roller or contact rail contact element 2, by the poles 3 and 4 of the electromagnet 8 on the contact element 5 "between the contact elements 2 and 5, it comes to a current flow through the voltage applied to a voltage Walzgut 1. The pole 4 of the electromagnet 8 is provided with a wear layer 6. After passing through the consisting of a light barrier signal generator 7 is switched on the electromagnet 8 and it comes due to the force on the rolling stock 1 to a deflection of the rod depending on the polarity of the magnetic field in the rolling direction to the left or right. The polarity of the magnetic field between the poles 3 and 4 is performed by. Exchange the polarity of the applied to the coil 9 of the electromagnet 8 Spaanung. In order to avoid heavy wear of the roller table part, to which the deflected rod strikes during further movement, these parts of the roller table 11 are likewise provided with a wearing layer 10.
