Problems solved by technology
[0012] The existing methods and corresponding devices for the positioning or adjustment of individual rolling units or roll units of rolling or continuous casting plants can be said to have the following disadvantages: the time required for adjustment is very long, especially after remodeling or after installation After maintenance; the utilization rate of the equipment is low, which leads to high operating costs; in addition, the positioning accuracy of a single unit is partially unqualified, so the product quality is not ideal; The reliability of the process is severely reduced and the failure rate increases
[0013] Although the different solutions of the prior art partly lead to improved results, this is not enough for a high-quality production or a quick and efficient adjustment of the rolling unit or the roll unit

Embodiment Construction
[0036] figure 1A schematic diagram of a casting machine 1 in the form of a continuous casting plant is shown. The molten metal flows out of a crystallizer 21 vertically downwards and gradually turns from vertical to horizontal along a casting segment 14 . The casting segment 14 is composed of several roller units 2 , 3 , 4 which are positioned relative to one another in such a way that they form the casting segment 14 . It should be pointed out here that in reality only the fan-shaped lower frame is shown, but this is not a problem as long as the dimension reference line always refers to the "rear edge of the strand". It is particularly advantageous for the variant described below that the measurement of the device can also be carried out with the upper frame assembled.
[0037] The pouring segment 14 has a center M, that is, the poured metal continuous casting slab turns into a quarter circle around the center M from vertical to horizontal.
[0038] A measuring device 5 in...

The invention relates to a method of precise positioning of a number of cooperating cylinder or roller elements (2, 3, 4) of a roller or casing installation (1) relative to each other. In order to be able to bring off a rapid and precise alignment of the cylinder or roller elements, according to the invention, it is provided that with a measuring apparatus (5), a distance (a6, a7, a8, a9) between at least three reference points (6, 7, 8, 9), which are provided directly or indirectly on each of the cylinder roller elements (2, 3, 4), and the measuring apparatus is measured, and that dependent on measurement results, adjusting elements (10, 11, 12) on each cylinder or roller element (2, 3, 4) are so operated that the distances (a6, a7, a8, a9) between the reference points (6, 7, 8, 9) and the measuring apparatus conform to predetermined values to a best possible extent, wherein the measurement points (6, 7, 8, 9) of each cylinder or roller element (2, 3, 4) are arranged, directly or indirectly on a carrier element (13) of the cylinder or roller element (2, 3, 4). The invention further relates to a roller or casting installation, in particular for carrying out the method.
Description
technical field [0001] The invention relates to a method for the mutual precise positioning of several cooperating rolling units or roll units of a rolling or continuous casting plant. Furthermore, the invention relates to a rolling or continuous casting plant with several cooperating rolling units or roll units. Background technique [0002] Especially in continuous casting installations, several cooperating roller units need to be aligned as precisely as possible relative to each other, wherein in the aligned state the roller units form a casting segment of the metal strand to be cast. [0003] As is well known, in order to carry out this alignment, the positions of the above-mentioned units must be determined with theodolites, levels or tilt plates. During the measurement, a number of reference points are generally taken, which are not fixed in position (thermal expansion, foundation settlement) relative to the ideal equipment size reference line, that is, usually the ma...
