Definitions
- Rolling device for in-line rolling of a steel strip produced in particular by two-roll strip casting
- the invention relates to a rolling device for an in-line rolling of a particular produced by a two-roll strip casting steel strip, which 'has at least two rolling units with the steel strip rolling work rolls and these work rolls supporting support rollers which are rotatably supported by bearing housings.
- This in-line rolling process can be applied by strip casting, in which the cast strips can be rolled immediately after casting in the hot state at temperatures of about 900 ° -1200 ° C, which is a very efficient process.
- the in-line rolling speeds of the cast strip are many times smaller, and only about 0.5 to 2.0 m / s instead of about 20 m / s.
- the rolling forces are very high, so that the rolling devices must be designed accordingly stable.
- the invention has the object of providing a rolling device, which is designed by a simple and inexpensive construction and by means of which the cast steel strip is rolled at the optimum time.
- This object is achieved according to the invention in that at least two rolling units are arranged directly one after the other in a single-part or multi-part frame construction.
- the invention further provides to replace the work rolls without having to interrupt the rolling, i. that they can be changed almost on the fly.
- Fig. 2 is a front view of the rolling device of Fig. 1
- Fig. 3 is a schematic representation of a casting plant with the rolling device.
- FIG. 1 and 2 show a rolling device 10 for in-line rolling of a steel strip 11, in particular produced by two-roll strip casting, as can also be seen in FIG. 3.
- This rolling device 10 is arranged at such a distance from the steel strip 11 generating casting rollers 41, 42, that the steel strip 11 has cooled sufficiently. It would also be possible to additionally cool the steel strip 11 by cooling panels not shown in detail before entering the rolling device 10. These cooling panels would be controllable so that with him the inlet temperature of the steel strip could be set to a selectable, as constant as possible over the width temperature.
- There are two roller units 20 and 30 are provided, each having a work roll located above and below the steel strip 11 21, 31 and one each with this work roll 21, 31 rotatably connected support roller 22, 32 have.
- These working 21, 31 and support rollers 22, 32 are located with their axes of rotation advantageously on a plane perpendicular to the extension of the steel strip 11 extending plane 20 ', 30'.
- the work rolls 21, 31 are coupled with indicated drive shafts 21 ', 31' of a drive member.
- the support rollers or both, the working and the support rollers could be driven.
- the two roller units 20, 30 are arranged directly successively in a frame construction 15. This results in the advantage that, on the one hand, the steel strip 11 cools only insignificantly from one to the next work rolls 21, 31. In addition, with this arrangement of the rolling device in comparison to conventional rolling mills also requires very little space and thus there are substantial cost savings.
- the frame structure 15 is formed of four spaced-apart vertical columns 16, 17, 18 and these connecting transverse webs 14, 19. But it could also be designed as a housing or a housing-like, frame, while the roles would be surrounded by him. This would be particularly suitable if the steel strip were held in an inerting chamber provided inside the frame housing.
- a respective support roller 22, 32 is rotatably mounted on both sides in a respective bearing housing 23, 24, 33, 34 together with the rotatably connected to her work roll 21, 31.
- two bearing housings 23, 33 are provided at the top and at the bottom, which are driven by a drive column 37 having a drive fastened to the upper transverse web 14 of the frame structure 15 36, for example, an electromechanical or a hydraulically acting spindle drive, in this perpendicular to the extension of the steel strip 11 extending plane 20 ', 30' are height adjustable.
- the lower rollers 21, 22, 31, 32 rotatably mounted on both sides in a respective bearing housing 33, 34, said bearing housing 33, 34 are in turn coupled to a drive column 37 of a fixed to the transverse web 19 of the frame structure 15 drive 39.
- the upper and lower bearing housings 23, 24, 33, 34 are on the inside directly to each other and on the outside of each column 17, 18 out. Between these bearing housings 23, 33 and 24, 34 are advantageously not shown measuring cells present, which measures and evaluates a force acting in the direction of the steel strip 11 horizontal force between these bearing housings, such that when exceeding a predetermined horizontal force, the rotational speeds of the work rolls 21, 31 from one to the other roller unit 20, 30 are adapted to reduce this horizontal force to zero or a predetermined horizontal force.
- a pair of infeed rollers 12, 13, which are additionally connected upstream of the roller units 20, 30, is provided, which is likewise provided in the frame assembly. struct 15 is stored.
- This inlet roller pair 12, 13 serves for a perfect guiding of the steel strip 11, in particular even when changing the work rolls.
- the work rolls 21, 31 may be slidably disposed in the direction of the invention in order to achieve a uniform wear in its axial direction, which is not shown in detail.
- both work rolls 21, 31 are arranged displaceably in the same direction.
- Fig. 3 shows a schematic representation of the rotatable during casting casting rollers 41, 42, which between these existing molten bath 44 and the produced steel strip 11, which deflects a loop from a vertical to a horizontal position and by guide rollers 12 ', 13', the Feeding rollers 12, 13 and through the work rollers 21, 31 is passed.
- the speed of the first reaching the steel strip 11 driven working rollers 21 of the roller unit 20 is brought in response to the rotational speed of the casting rollers 41, 42, while the rotational speed of the subsequent driven work rolls 31 in dependence on the speed of the upstream work rolls 21 takes place.
- a coordinated control of the speeds and thus a rolling of the steel strip 11 can be achieved without the steel strip 11 between the pairs of work rolls 21, 31 spans or becomes too loose.
- the arrangement of the working and supporting rollers of a roller unit may be selected from a so-called 4-Hi (as shown), a 6-Hi or a Z-Hi.
