Problems solved by technology

[0004] All casting variants have the disadvantage of producing large castings with a correspondingly high degree of difficulty and corresponding casting risks
A further disadvantage is that, due to the high component weight, higher demands must be placed on the manufacturing machinery to be used
As a result, options for foundries and fabricators are limited, which additionally creates commercial constraints

Embodiment Construction

[0034] According to FIG. 1 , the main assembly 1 consists of two transverse beams 1 a and 1 b and four longitudinal beams 4 a and 4 b. At the transition to the transverse beams 1a, 1b, a connection point 3 with a covering part 3a is formed in each case.

[0035] In the illustrated six-part embodiment of the main assembly 1, which consists of two transverse beams 1a, 1b and four longitudinal beams 4a, 4b, a cross arm 11 or a projection 19 is formed on the respective longitudinal beam end 6. The cruciform 7.

[0036] The connection between the crossbeams 1a, 1b and the longitudinal girders 4a, 4b is realized by means of through-threads 5, wherein the crossbeams and the longitudinal girders are respectively supported on a support plate not shown in detail below the crossbeam base 8, said through-beams being held by Prestressing and thus forming a joint in the material expandable axially and transversely. The longitudinal beam ends 6 are connected via crosses 7 to the transverse...

Abstract

Disclosed is a roll stand for edgers in rolling mills. Said roll stand is embodied in several pieces, comprising two crossheads (1a, 1b) and four longitudinal bars (4a, 4b) as main components (1) as well as one respective common cruciform (7) junction point (3) for the crosshead (1a, 1b) and the longitudinal bars (4a, 4b), which is located at the ends (6) of the longitudinal bars. Pretensioned through bolts (5) that act as a joint are used at least at the top ends (6) of the longitudinal bars.

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 ...
