Description

The invention relates to a method and a device for the assembly and functional testing of rolling fittings in rolling mills or in rolling mills, such as. Tandem rolling mills, wherein at least a part number of rolling fittings each forms a structural unit which is operatively attached to the respective roll stand and wherein the structural units arranged, set and / or tested for pre-assembly with functional tests outside the rolling stand and at least one set and / or tested unit operatively arranged between two rolling stands predominantly in the framework gap and attached to constructively defined support points of the roll stand.

From the EP 0 369 269 A is the initially described object known, but at the inlet and outlet side of a single stand each a supporting body is attached via two additional support beams to two support beams connected to the stand beams. This solution makes it possible to attach and adjust the guide elements outside the rolling train at a specially equipped mounting position on the additional support beams, before they are connected to the rolling stand together with the additional support beam. In this case, an additional support beam already located on the scaffold can be exchanged for the additional support beam equipped with the set guide elements. Indeed For a setting of the guide elements on the roll stand still laterally hinged to the stand rails lifting motors required.

From the DE 23 56 785 B In addition, a rolling fitting with upper and lower Walzgutführungen for attachment to the inlet and outlet side of rolling stands is known. Both rolling stock guides are mounted within a common frame, which is guided and can be aligned.

An assembly is also from the EP 0 349 840 A2 There, to be replaced essentially outside of the mill stand of the rolling mill separate building units, which not only require additional and relatively large space requirements, but also difficult to access and accordingly difficult to maintain and operate. It is a unit described as known with rolling mill on the inlet and outlet side arranged Bandabweisem, sprayers, rolled strip lifting devices, Ausfahrschienen and rolled strip guide tables, the rolled strip lifting devices with tape deflectors, sprayers, Ausfahrschienen and Walzbandleittisch together to form a unit and within the Rolling stand are arranged in close proximity to the nip of the work rolls. The individual devices can also be integrated in the work roll bending block. Although such a construction method has proven successful, there are still some problem areas to be improved that have so far remained unconsidered.

The invention has for its object to simplify the handling of the assembly when mounting and functional testing and perform the work faster and more time-saving.

The stated object is achieved according to the invention in that in the rolling direction in the first rolling stand of a rolling train an outside of the rolling stand set on a mounting plate and / or tested inlet side module between the associated roller stands of the respective first rolling stand is installed and that mounted in the rolling direction between a first rolling stand and a second rolling stand also set outside the rolling stand on the mounting plate and / or checked outlet side module and an inlet side module supported on a base frame. A significant advantage is a possible pre-examination of all elements outside of the mill stand, for example. In the workshop, a time-saving Vorverkabelung the sensor and a piping of media consumers. As a result, the final assembly in the rolling mill is considerably simplified, for example, shortened in time, because not more individual assemblies are mounted and tested, but a compact unit. Consequently, assembly times on the construction site are saved, the commissioning time is shortened, and fastening points on the rolling stand can already be selected and determined during the design phase, these design advantages being independent of the components to be installed. Overall, there are significant time and cost savings.

In Fig. 1 are two lying on a rolling line 6, single stands 1 shown. Each rolling stand 1 consists of (transverse to the rolling direction 11) one behind the other roller stands 1 a and 1 b. Several such rolling mills 1 form a rolling train 2. Thus, for example, a series of five rolling mills 1 represent a tandem rolling mill 3. Each of the rolling stands 1 is equipped with rolling fittings 4. The rolling fittings 4 form the same and / or similar and / or different structural units 5. Such assemblies 5 are referred to as "modules".

The structural units 5 are used as inlet side modules 12 and outlet side module 13 in each rolling mill 1 and in the framework gap 9 on a base frame 8 (see Fig. 2 and 3 ) attached. The base frame 8 forms in the framework space 9 a special, independent structural unit 5. This base frame 8 consists of two trusses 19, side protection walls 17 a, 17 b and a grid 21st

In the framework space 9 are located on the base frame 8 left side outlet side module 13 and right side inlet side module 12. These units 5 in the framework gap 9 are structurally associated with a support point 10 and fixed there. The support points 10 can already be determined during the design phase, regardless of the units 5 to be installed.

The advantages of the invention are essentially achieved in that the units 5 for pre-assembly with functional tests on a mounting plate (not shown) outside of the roll stand 1, for example. In a workshop, arranged on the mounting plate, set outside of the roll stand 1 and / or be checked and that at least one set and / or tested unit 5 between two rolling stands predominantly arranged in the framework gap 9 and attached to constructively definable support points 10 of the roll stand 1 a, 1 b.

In the following, examples of a structural unit 5 as the inlet side module 12 will be described. The rolling taps 4 have input side spray bars 14 for emulsions. For this purpose, an upper spray bar 15a for the nip lubrication and a lower spray bar 15b for the nip lubrication are provided. Before that, a band clamp 16 is arranged. The rolled strip is guided by means of a belt guide table 18. In the rolling direction 11, such a unit 5 may be arranged in the first rolling stand 1 of a rolling train 2 as inlet side module 12 between the mutually associated roll stands 1 a, 1 b.

The assembly 5 in the framework space 9 is mounted on the base frame 8, two trusses 19 with double-sided side walls 17 a, 17 b, wherein for the work of the operator a grid 21 is used. The base frame 8 is held at the support points 10.

The belt deflector 22 is associated with a lower work roll 23b. The rolling fittings 4 are attached to stator walls 24. Associated with the set of rolls of work and back-up rolls is a space-cleaning bar 25 and an upper cleaning and cooling bar 26a and a lower cleaning and cooling bar 26b. Between the components is a tape data measuring device 27. Before entering the right mill stand 1 is a tape tension measuring roller 28. This surrounding is a support and a protective device 29 for the components of the belt speed determination. In addition, a carrier 30 for the belt speed measuring apparatus is fixed to the base frame 8. A protective device 31 for the strip thickness measuring device is shown. Next, a stationary tape guide table 32 with a belt hold-down roller 33 with integrated belt cooling device is shown. The assembly 5, ie the inlet side module 12, here forms a framework gap input module 34. Accordingly, an input side emulsion spray bar 35 is formed (analogous to the input side spray bar 14). This consists (analogous to 15a, 15b) of an upper spray bar 36a for the nip lubrication and a lower spray bar 36b for the nip lubrication. In addition, here has the outlet side module 13 an emulsion spray system 37 with a multi-zone cooling lubrication. Analogous to the spray bars 15a, 15b are provided an upper spray bar 38a for roll gap lubrication and multi-zone cooling and a lower spray bar 38b for roll gap lubrication and multi-zone cooling. The space-cleaning bar 25 corresponds to a space-cleaning bar 40, respectively. The strip-clamping device 16 corresponds to a tape-clamping device 41 with accessories, wherein the drive range of the band clamp 41 is indicated at 42. These elements are attached to a stator wall 43. Also provided are a guide table 44 and a pivotable tape guide table 45.

In Fig. 2 is the structure for pre-assembly with functional tests outside the rolling line 6, for example. In a workshop, shown. The inlet side modules 12 and the outlet side modules 13 are provided with the associated splash guard walls 7a and 7b. The base frame 8 is provided for later attachment to the roller stands 1a, 1b by means of side protection walls 17a, 17b.
