Continuous fine mill

The invention relates to a continuous fine rolling mill with several rolling stands connected in series.

En scaffold with such rolling, it is necessary between the individual rolling stands to provide a length compensation for the rolling _s a draft-free rolls to enable. At the same time it is also necessary to create a controlled variable su for the roll control of the roll stands.

It is known to meet this requirement, the whale material between the individual whale frames in Guide the loops. First of all, the noose saves a little length of Walsgut, which means that there are slight differences in rotational speed automatically balanced. The resulting change in the shape of the loop is then used as a control variable, usually by electrical means, to control the roller speed.

However, these loops initially increase the distance between the roll stands in a useless manner. Furthermore, there are complex and fault-prone roller rolls necessary to straighten the bent rod before it enters the actual scaffolding, which causes difficulties especially with thick rods and profile rods. Finally, the rolling rod is between each roll stand three times bent unnecessarily at relatively sharp angles.

The invention is based on the object of avoiding these disadvantages mentioned, a simple and To create a trouble-free construction in order to reduce the space requirement.

This object is achieved in that a roll stand between two roll stands in the Loop belly is arranged. While three roll stands used to require two loops, they can now three roll stands can be arranged with only one loop, which is only slightly longer than with the known arrangement. Furthermore, by avoiding a loop, there are three bends in the roll bar saved.

The construction is carried out in such a way that the piercing is carried out between the two roll stands The roll stand can be moved vertically and laterally until all stands are aligned on a rolling line, whereupon the The scaffolding located between the scaffolding is moved back into the operating position. This will be Above all, the complex and failure-prone calibration rolls for inserting the roller rod are avoided. Through this, that when piercing all the stands are aligned on a rolling line, the rod can easily move into the stands introduced v / earth. Only then is the middle framework raised or lowered. But it still remains In the subject matter of the invention, a loop for balancing tension and for achieving a. Controlled variable for the roller control.

The drawing shows an exemplary embodiment of the invention in a schematic representation.

In the drawing, the roll stands are denoted by 1, 2 and 3. ¹ J is the rolling rod. The middle roll stand 2 is vertically or laterally displaceable in the direction of arrow a.

Mode of action:

For the piercing, the middle roll stand 2 is shifted so that all roll stands are aligned in a rolling line. Then the rolling rod H is introduced into the rolling stands. Now the middle rolling stand 2 is shifted vertically or laterally by the amount a, whereupon the rolling train is ready for operation
