DE1908004B2 - Continuous fine rolling mill - Google Patents

Description

The invention relates to a continuous fine rolling mill with at least three on a straight rolling

line series-connected roll frames and Loops between the stands, which after piercing in the two neighboring roll stands through Devices for deflecting the rolling stock are formed from the straight rolling line. .

In such rolling mills it is necessary to have two To create a length compensation for the rolling stock in the individual roll stands in order to achieve a tension-free Enable rolling. At the same time it is also necessary to create a control variable for the roll control of the roll stands.

It is known to meet this requirement to guide the rolling stock between the individual roll stands m loops. The noose stores basically something the rolling stock, which genngfug _lg e speed differences are automatically compensated. Which caused by it? The change in the loop shape is then used as a control variable, usually electrically, to control the roller speed.

¹¹⁰ SeSe task is solved according to the invention! that to form the loops, the roll stand arranged between two roll stands can be shifted from the lie hcheii- or laterally. As a result of the proposal, the bending angle of the rolling mill is reduced so that the rolling stands can stand closer together and the material is subjected to less stress. Whereas in the past roll stands required two loops, now three roll stands can be fitted with only one loop, which is only slightly longer than a ₅ with an above-mentioned arrangement.

In addition, the complex and prone to failure No need for straightening rollers to insert the rod. As a result of the fact that all scaffolding during the piercing can be arranged in alignment on a rolling line, the rod can easily be in the stands to be introduced. Only then will the middle Geiten method be used.
