Description

technical field

[0001] The invention relates to a rolling stand for an edger stand in a rolling mill, which is constructed in multiple parts and consists of main components, such as cross members and longitudinal members, which are connected to one another by means of screws. Background technique

[0002] The mill stands used for the edging stands are mostly cast structures and are used to accommodate the components necessary for the edging process, such as adjustment, balancing, edging roll sets, transmissions, motors, etc.

[0003] Cast constructions in the form of a two-part construction are known, in which the roll stand has a horizontal dividing weld and the two halves are connected in a form-fitting manner, for example by means of shrink rings.

[0004] All casting variants have the disadvantage that large cast parts have to be produced with a correspondingly high degree of difficulty and corresponding casting risks. A further disadvantage is that higher demands must ...
